4. FIRST AID MEASURES

FIRST AID FOR EYES ………………………………………………………………. SYMPTOMS: Causes eye burns and eye damage. RESPONSE: Flush
immediately with water for at least 15 minutes. Remove contact lenses if present and easy to do. Immediately call a POISON CONTROL CENTER
or doctor.

FIRST AID FOR SKIN ……………………………………………………………….. SYMPTOMS: Causes skin burns, redness and irritation. May cause allergic
skin reaction and sensitization. RESPONSE: Immediately wash skin with soap and water. Immediately call a POISON CONTROL CENTER or
doctor.

FIRST AID FOR INHALATION …………………………………………………… SYMPTOMS: May cause allergy or asthma symptoms or breathing
difficulties. Can cause respiratory irritation, shortness of breath or cough. Exposure to concentrated vapors, fumes or mist can cause damage to
lung tissue. RESPONSE: Remove to fresh air if effects occur and keep comfortable for breathing. Immediately call POISON CONTROL CENTER
or doctor if symptoms develop and persist.

FIRST AID FOR INGESTION ……………………………………………………… SYMPTOMS: May cause gastrointestinal irritation or ulceration. May
cause burns of the mouth and throat. RESPONSE: Rinse mouth with water. DO NOT induce vomiting. If vomiting should occur, keep airway
clear. Immediately call POISON CONTROL CENTER or doctor.

5. FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA: …………………………………………………………. SUITABLE: Foam, carbon dioxide (CO2), dry chemical. NON-SUITABLE:
Direct water stream.

FIRE AND EXPLOSION HAZARDS: …………………………………………… During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to: oxides
of nitrogen, carbon monoxide, carbon dioxide, volatile amines, ammonia, nitric acid, aldehydes. When mixed with sawdust, wood chips, or other
cellulosic material, spontaneous combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. If the heat is not
dissipated quickly enough, it can ignite the sawdust.

SPECIAL FIRE FIGHTING PROCEDURES: …………………………………. Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses.

6. ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDURES : ………………………………………………….. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.

MITIGATION AND CLEAN UP PROCEDURES: …………………………… Stop leak without additional risk. Isolate area. Dike and absorb with inert
material (e.g., sand) and collect in a suitable, closed container. Do not use sawdust, wood chips or other cellulosic materials to absorb the spill, as
the possibility for spontaneous combustion exists. Warm, soapy water may be used to clean residual.

ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Prevent from entering into soil, ditches, sewers, waterways and
groundwater. See Section 12 for environmental impact information.

7. HANDLING AND STORAGE

STORAGE TEMPERATURE (min./max.): ……………………………………. 40 F (4 C) / 90 F (32 C).

STORAGE: ……………………………………………………………………………… Store in cool, dry place away from high temperatures and moisture. Keep
container tightly closed. Avoid direct sunlight. Store in a secure location with restricted access or store locked up.

HANDLING PRECAUTIONS: …………………………………………………….. Use with adequate ventilation. Do not breathe vapors or mists from heated
material. Avoid exposure to concentrated vapors. Avoid skin and eye contact. Wash thoroughly after handling. When mixed with epoxy resin
this product causes an exothermic reaction, which in large masses, can produce enough heat to undergo thermal decomposition damage or ignite
surrounding materials. Fumes and vapors released as a result of thermal decomposition can vary widely in composition and toxicity.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

ENGINEERING CONTROLS: …………………………………………………….. Use with adequate general ventilation and/or local ventilation to keep
exposures below established limits.

EYE PROTECTION GUIDELINES: ……………………………………………… Chemical splash-proof goggles or face shield.

SKIN PROTECTION GUIDELINES:…………………………………………….. Wear liquid-proof, chemical resistant gloves (nitrile-butyl rubber, neoprene,
butyl rubber or natural rubber) and full body-covering clothing.

RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with an organic vapor cartridge, organic vapor cartridge + P100, or a multi-contaminant
cartridge, depending on specific workplace conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator
and cartridge based on ingredients listed in Section 3 and specific workplace conditions. Use and select a respirator according the guidelines
established in OSHA 1910.134 or other applicable respiratory protection standard.

ADDITIONAL PROTECTIVE MEASURES: ………………………………….. Use where there is immediate access to safety shower and emergency eye
wash. Wash thoroughly after use. Contact lens should not be worn when working with this material. Generally speaking, working cleanly and
following basic precautionary measures will greatly minimize the potential for harmful exposure to this product under normal use conditions.

of nitrogen, carbon monoxide, carbon dioxide, volatile amines, ammonia, nitric acid, aldehydes. When mixed with sawdust, wood chips, or other
cellulosic material, spontaneous combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. If the heat is not
dissipated quickly enough, it can ignite the sawdust.

SPECIAL FIRE FIGHTING PROCEDURES: …………………………………. Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses.

EMERGENCY PROCEDURES : ………………………………………………….. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.

MITIGATION AND CLEAN UP PROCEDURES: …………………………… Stop leak without additional risk. Isolate area. Dike and absorb with inert
material (e.g., sand) and collect in a suitable, closed container. Do not use sawdust, wood chips or other cellulosic materials to absorb the spill, as
the possibility for spontaneous combustion exists. Warm, soapy water may be used to clean residual.

ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Prevent from entering into soil, ditches, sewers, waterways and
groundwater. See Section 12 for environmental impact information.

7. HANDLING AND STORAGE

STORAGE TEMPERATURE (min./max.): ……………………………………. 40 F (4 C) / 90 F (32 C).

STORAGE: ……………………………………………………………………………… Store in cool, dry place away from high temperatures and moisture. Keep

SKIN PROTECTION GUIDELINES:…………………………………………….. Wear liquid-proof, chemical resistant gloves (nitrile-butyl rubber, neoprene,
butyl rubber or natural rubber) and full body-covering clothing.

RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with an organic vapor cartridge, organic vapor cartridge + P100, or a multi-contaminant
cartridge, depending on specific workplace conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator
and cartridge based on ingredients listed in Section 3 and specific workplace conditions. Use and select a respirator according the guidelines
established in OSHA 1910.134 or other applicable respiratory protection standard.

ADDITIONAL PROTECTIVE MEASURES: ………………………………….. Use where there is immediate access to safety shower and emergency eye

4. FIRST AID MEASURES

FIRST AID FOR EYES ………………………………………………………………. SYMPTOMS: Causes eye burns and eye damage. RESPONSE: Flush
immediately with water for at least 15 minutes. Remove contact lenses if present and easy to do. Immediately call a POISON CONTROL CENTER
or doctor.

FIRST AID FOR SKIN ……………………………………………………………….. SYMPTOMS: Causes skin burns, redness and irritation. May cause allergic
skin reaction and sensitization. RESPONSE: Immediately wash skin with soap and water. Immediately call a POISON CONTROL CENTER or
doctor.

FIRST AID FOR INHALATION …………………………………………………… SYMPTOMS: Exposure to high vapor concentrations can cause respiratory
irritation. RESPONSE: Remove to fresh air if effects occur and keep comfortable for breathing. Immediately call POISON CONTROL CENTER or
doctor.
Notes to physician: Exposure to material may cause delayed lung injury resulting in pulmonary edema and pneumonitis. Exposed individuals
should be monitored for 72 hours after exposure for the onset of delayed respiratory symptoms (severity of effects is dependent upon extent of
exposure).

FIRST AID FOR INGESTION ……………………………………………………… SYMPTOMS: May cause gastrointestinal irritation or ulceration. May
cause burns of the mouth and throat. RESPONSE: Rinse mouth with water. DO NOT induce vomiting. If vomiting should occur, keep airway
clear. Immediately call POISON CONTROL CENTER or doctor.
Notes to physician: Use of gastric lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should be investigated. Do
not give chemical antidotes. Asphyxia from glottal edema may occur. Marked decrease in blood pressure may occur with moist rales, frothy
sputum, and high pulse pressure. Treat symptomatically.

5. FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA: …………………………………………………………. SUITABLE: Foam, carbon dioxide (CO2), dry chemical. NON-SUITABLE:
Direct water stream.

FIRE AND EXPLOSION HAZARDS: …………………………………………… During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to: oxides
of nitrogen, carbon monoxide, carbon dioxide, volatile amines, ammonia, nitric acid, aldehydes, phenolics. When mixed with sawdust, wood chips,
or other cellulosic material, spontaneous combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. If the
heat is not dissipated quickly enough, it can ignite the sawdust.

SPECIAL FIRE FIGHTING PROCEDURES: …………………………………. Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses.

6. ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDURES: ………………………………………………….. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.

MITIGATION AND CLEAN UP PROCEDURES: …………………………… Stop leak without additional risk. Isolate area. Dike and absorb with inert
material (e.g., sand) and collect in a suitable, closed container. Do not use sawdust, wood chips or other cellulosic materials to absorb the spill, as
the possibility for spontaneous combustion exists. Warm, soapy water may be used to clean residual.

ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Prevent from entering into soil, ditches, sewers, waterways and
groundwater. See Section 12 for environmental impact information.

7. HANDLING AND STORAGE

Entropy Resins

Clear Fast Hardener
Page 3 of 6 Last Revised: 19JAN23
STORAGE TEMPERATURE (min./max.): ……………………………………. 40 F (4 C) / 90 F (32 C).

STORAGE: ……………………………………………………………………………… Store in cool, dry place away from high temperatures and moisture. Keep
container tightly closed. Store in a secure location with restricted access or store locked up. Store away from incompatible materials identified in
Section 10.

HANDLING PRECAUTIONS: …………………………………………………….. Use with adequate ventilation. Do not breathe concentrated vapors or
mist/aerosols. Avoid skin contact and eye contact. Wash hands thoroughly after handling. When mixed with epoxy resin this product causes an
exothermic reaction, which in large masses, can produce enough heat to damage or ignite surrounding materials and emit fumes and vapors that
vary widely in composition and toxicity.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

ENGINEERING CONTROLS: …………………………………………………….. Use with adequate general ventilation and/or local ventilation to keep
exposures below established limits.

EYE PROTECTION GUIDELINES: ……………………………………………… Chemical splash-proof goggles or face shield.

SKIN PROTECTION GUIDELINES: …………………………………………….. Wear liquid-proof, chemical resistant gloves (nitrile-butyl rubber, neoprene,
butyl rubber or natural rubber) and full body-covering clothing.

RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with organic vapor, organic vapor + P100, or multi-contaminant cartridge, depending on
specific workplace conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator and cartridge based on
ingredients listed in Section 3 and specific workplace conditions. Use and select a respirator according the guidelines established in OSHA
1910.134 or other applicable respiratory protection standard.

ADDITIONAL PROTECTIVE MEASURES: ………………………………….. Use where there is immediate access to safety shower and emergency eye
wash. Wash thoroughly after use. Contact lens should not be worn when working with this material. Generally speaking, working cleanly and
following basic precautionary measures will greatly minimize the potential for harmful exposure to this product under normal use conditions.

OCCUPATIONAL EXPOSURE LIMITS: ………………………………………. Exposure limits may not be established for this product as a whole. For

5. FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA: …………………………………………………………. SUITABLE: Foam, carbon dioxide (CO2), dry chemical. NON-SUITABLE:
Direct water stream.

FIRE AND EXPLOSION HAZARDS: …………………………………………… During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to: oxides
of nitrogen, carbon monoxide, carbon dioxide, volatile amines, ammonia, nitric acid, aldehydes, phenolics. When mixed with sawdust, wood chips,
or other cellulosic material, spontaneous combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. If the
heat is not dissipated quickly enough, it can ignite the sawdust.

SPECIAL FIRE FIGHTING PROCEDURES: …………………………………. Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses.

6. ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDURES: ………………………………………………….. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.

MITIGATION AND CLEAN UP PROCEDURES: …………………………… Stop leak without additional risk. Isolate area. Dike and absorb with inert
material (e.g., sand) and collect in a suitable, closed container. Do not use sawdust, wood chips or other cellulosic materials to absorb the spill, as
the possibility for spontaneous combustion exists. Warm, soapy water may be used to clean residual.

ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Prevent from entering into soil, ditches, sewers, waterways and
groundwater. See Section 12 for environmental impact information.

7. HANDLING AND STORAGE

exposures below established limits.

EYE PROTECTION GUIDELINES: ……………………………………………… Chemical splash-proof goggles or face shield.

SKIN PROTECTION GUIDELINES: …………………………………………….. Wear liquid-proof, chemical resistant gloves (nitrile-butyl rubber, neoprene,
butyl rubber or natural rubber) and full body-covering clothing.

RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with organic vapor, organic vapor + P100, or multi-contaminant cartridge, depending on
specific workplace conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator and cartridge based on
ingredients listed in Section 3 and specific workplace conditions. Use and select a respirator according the guidelines established in OSHA
1910.134 or other applicable respiratory protection standard.

ADDITIONAL PROTECTIVE MEASURES: ………………………………….. Use where there is immediate access to safety shower and emergency eye
wash. Wash thoroughly after use. Contact lens should not be worn when working with this material. Generally speaking, working cleanly and

4. FIRST AID MEASURES

FIRST AID FOR EYES ………………………………………………………………. SYMPTOMS: Causes eye burns and eye damage. RESPONSE: Flush
immediately with water for at least 15 minutes. Remove contact lenses if present and easy to do. Immediately call a POISON CONTROL CENTER
or doctor.

FIRST AID FOR SKIN ……………………………………………………………….. SYMPTOMS: Causes skin burns, redness and irritation. May cause allergic
skin reaction and sensitization. RESPONSE: Immediately wash skin with soap and water. Immediately call a POISON CONTROL CENTER or
doctor.

FIRST AID FOR INHALATION …………………………………………………… SYMPTOMS: Exposure to high vapor concentrations can cause respiratory
irritation. RESPONSE: Remove to fresh air if effects occur and keep comfortable for breathing. Immediately call POISON CONTROL CENTER or
doctor.
Notes to physician: Exposure to material may cause delayed lung injury resulting in pulmonary edema and pneumonitis. Exposed individuals
should be monitored for 72 hours after exposure for the onset of delayed respiratory symptoms (severity of effects is dependent upon extent of
exposure).

FIRST AID FOR INGESTION ……………………………………………………… SYMPTOMS: May cause gastrointestinal irritation or ulceration. May
cause burns of the mouth and throat. RESPONSE: Rinse mouth with water. DO NOT induce vomiting. If vomiting should occur, keep airway
clear. Immediately call POISON CONTROL CENTER or doctor.
Notes to physician: Use of gastric lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should be investigated. Do
not give chemical antidotes. Asphyxia from glottal edema may occur. Marked decrease in blood pressure may occur with moist rales, frothy
sputum, and high pulse pressure. Treat symptomatically.

5. FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA: …………………………………………………………. SUITABLE: Foam, carbon dioxide (CO2), dry chemical. NON-SUITABLE:
Direct water stream.

FIRE AND EXPLOSION HAZARDS: …………………………………………… During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to: oxides
of nitrogen, carbon monoxide, carbon dioxide, volatile amines, ammonia, nitric acid, aldehydes, phenolics. When mixed with sawdust, wood chips,
or other cellulosic material, spontaneous combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. If the
heat is not dissipated quickly enough, it can ignite the sawdust.

SPECIAL FIRE FIGHTING PROCEDURES: …………………………………. Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses.

6. ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDURES: ………………………………………………….. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.

MITIGATION AND CLEAN UP PROCEDURES: …………………………… Stop leak without additional risk. Isolate area. Dike and absorb with inert
material (e.g., sand) and collect in a suitable, closed container. Do not use sawdust, wood chips or other cellulosic materials to absorb the spill, as
the possibility for spontaneous combustion exists. Warm, soapy water may be used to clean residual.

ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Prevent from entering into soil, ditches, sewers, waterways and
groundwater. See Section 12 for environmental impact information.

7. HANDLING AND STORAGE

Entropy Resins

Clear Fast Hardener
Page 3 of 6 Last Revised: 19JAN23
STORAGE TEMPERATURE (min./max.): ……………………………………. 40 F (4 C) / 90 F (32 C).

STORAGE: ……………………………………………………………………………… Store in cool, dry place away from high temperatures and moisture. Keep
container tightly closed. Store in a secure location with restricted access or store locked up. Store away from incompatible materials identified in
Section 10.

HANDLING PRECAUTIONS: …………………………………………………….. Use with adequate ventilation. Do not breathe concentrated vapors or
mist/aerosols. Avoid skin contact and eye contact. Wash hands thoroughly after handling. When mixed with epoxy resin this product causes an
exothermic reaction, which in large masses, can produce enough heat to damage or ignite surrounding materials and emit fumes and vapors that
vary widely in composition and toxicity.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

ENGINEERING CONTROLS: …………………………………………………….. Use with adequate general ventilation and/or local ventilation to keep
exposures below established limits.

EYE PROTECTION GUIDELINES: ……………………………………………… Chemical splash-proof goggles or face shield.

SKIN PROTECTION GUIDELINES: …………………………………………….. Wear liquid-proof, chemical resistant gloves (nitrile-butyl rubber, neoprene,
butyl rubber or natural rubber) and full body-covering clothing.

RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with organic vapor, organic vapor + P100, or multi-contaminant cartridge, depending on
specific workplace conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator and cartridge based on
ingredients listed in Section 3 and specific workplace conditions. Use and select a respirator according the guidelines established in OSHA
1910.134 or other applicable respiratory protection standard.

ADDITIONAL PROTECTIVE MEASURES: ………………………………….. Use where there is immediate access to safety shower and emergency eye
wash. Wash thoroughly after use. Contact lens should not be worn when working with this material. Generally speaking, working cleanly and
following basic precautionary measures will greatly minimize the potential for harmful exposure to this product under normal use conditions.

(CBI). Any ingredient not disclosed in this section may have been determined not to be hazardous to health or the environment, or it may
be present at a level below its disclosure threshold.

4. FIRST AID MEASURES

FIRST AID FOR EYES ………………………………………………………………. SYMPTOMS: Causes eye burns and eye damage. RESPONSE: Flush
immediately with water for at least 15 minutes. Remove contact lenses if present and easy to do. Immediately call a POISON CONTROL CENTER
or doctor.

FIRST AID FOR SKIN ……………………………………………………………….. SYMPTOMS: Causes skin burns, redness and irritation. May cause allergic
skin reaction and sensitization. RESPONSE: Immediately wash skin with soap and water. Immediately call a POISON CONTROL CENTER or
doctor.

FIRST AID FOR INHALATION …………………………………………………… SYMPTOMS: Exposure to high vapor concentrations can cause respiratory
irritation. RESPONSE: Remove to fresh air if effects occur and keep comfortable for breathing. Immediately call POISON CONTROL CENTER or
doctor.
Notes to physician: Exposure to material may cause delayed lung injury resulting in pulmonary edema and pneumonitis. Exposed individuals
should be monitored for 72 hours after exposure for the onset of delayed respiratory symptoms (severity of effects is dependent upon extent of
exposure).

FIRST AID FOR INGESTION ……………………………………………………… SYMPTOMS: May cause gastrointestinal irritation or ulceration. May
cause burns of the mouth and throat. RESPONSE: Rinse mouth with water. DO NOT induce vomiting. If vomiting should occur, keep airway
clear. Immediately call POISON CONTROL CENTER or doctor.
Notes to physician: Use of gastric lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should be investigated. Do
not give chemical antidotes. Asphyxia from glottal edema may occur. Marked decrease in blood pressure may occur with moist rales, frothy
sputum, and high pulse pressure. Treat symptomatically.

5. FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA: …………………………………………………………. SUITABLE: Foam, carbon dioxide (CO2), dry chemical. NON-SUITABLE:
Direct water stream.

FIRE AND EXPLOSION HAZARDS: …………………………………………… During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to: oxides
of nitrogen, carbon monoxide, carbon dioxide, volatile amines, ammonia, nitric acid, aldehydes, phenolics. When mixed with sawdust, wood chips,
or other cellulosic material, spontaneous combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. If the
heat is not dissipated quickly enough, it can ignite the sawdust.

SPECIAL FIRE FIGHTING PROCEDURES: …………………………………. Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses.

6. ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDURES: ………………………………………………….. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.

MITIGATION AND CLEAN UP PROCEDURES: …………………………… Stop leak without additional risk. Isolate area. Dike and absorb with inert
material (e.g., sand) and collect in a suitable, closed container. Do not use sawdust, wood chips or other cellulosic materials to absorb the spill, as
the possibility for spontaneous combustion exists. Warm, soapy water may be used to clean residual.

ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Prevent from entering into soil, ditches, sewers, waterways and
groundwater. See Section 12 for environmental impact information.

7. HANDLING AND STORAGE

Entropy Resins

Clear Fast Hardener
Page 3 of 6 Last Revised: 19JAN23
STORAGE TEMPERATURE (min./max.): ……………………………………. 40 F (4 C) / 90 F (32 C).

STORAGE: ……………………………………………………………………………… Store in cool, dry place away from high temperatures and moisture. Keep
container tightly closed. Store in a secure location with restricted access or store locked up. Store away from incompatible materials identified in
Section 10.

HANDLING PRECAUTIONS: …………………………………………………….. Use with adequate ventilation. Do not breathe concentrated vapors or
mist/aerosols. Avoid skin contact and eye contact. Wash hands thoroughly after handling. When mixed with epoxy resin this product causes an
exothermic reaction, which in large masses, can produce enough heat to damage or ignite surrounding materials and emit fumes and vapors that
vary widely in composition and toxicity.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

ENGINEERING CONTROLS: …………………………………………………….. Use with adequate general ventilation and/or local ventilation to keep
exposures below established limits.

EYE PROTECTION GUIDELINES: ……………………………………………… Chemical splash-proof goggles or face shield.

SKIN PROTECTION GUIDELINES: …………………………………………….. Wear liquid-proof, chemical resistant gloves (nitrile-butyl rubber, neoprene,
butyl rubber or natural rubber) and full body-covering clothing.

RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with organic vapor, organic vapor + P100, or multi-contaminant cartridge, depending on
specific workplace conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator and cartridge based on
ingredients listed in Section 3 and specific workplace conditions. Use and select a respirator according the guidelines established in OSHA
1910.134 or other applicable respiratory protection standard.

ADDITIONAL PROTECTIVE MEASURES: ………………………………….. Use where there is immediate access to safety shower and emergency eye
wash. Wash thoroughly after use. Contact lens should not be worn when working with this material. Generally speaking, working cleanly and
following basic precautionary measures will greatly minimize the potential for harmful exposure to this product under normal use conditions.

OCCUPATIONAL EXPOSURE LIMITS: ………………………………………. Exposure limits may not be established for this product as a whole. For

cause burns of the mouth and throat. RESPONSE: Rinse mouth with water. DO NOT induce vomiting. If vomiting should occur, keep airway
clear. Immediately call POISON CONTROL CENTER or doctor.

5. FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA: …………………………………………………………. SUITABLE: Foam, carbon dioxide (CO2), dry chemical. NON-SUITABLE:
Direct water stream.

FIRE AND EXPLOSION HAZARDS: …………………………………………… During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to: oxides
of nitrogen, carbon monoxide, carbon dioxide, volatile amines. When mixed with sawdust, wood chips, or other cellulosic material, spontaneous
combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. If the heat is not dissipated quickly enough, it
can ignite the sawdust.

SPECIAL FIRE FIGHTING PROCEDURES: …………………………………. Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses.

6. ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDUR ES: ………………………………………………….. Keep unnecessary and unprotected personnel from entering area. Use
appropriate safety and personal protective equipment as indicated in Section 8.

MITIGATION AND CLEAN UP PROCEDURES: …………………………… Stop leak without additional risk. Isolate area. Dike and absorb with inert
material (e.g., sand, diatomaceous earth) and collect in a suitable, closed container. Do not use sawdust, wood chips or other cellulosic materials
to absorb the spill, as the possibility for spontaneous combustion exists. Warm, soapy water may be used to clean residual.

ENVIRONMENTAL PRECAUTIONS: ………………………………………….. Prevent from entering into soil, ditches, sewers, waterways and
groundwater. See Section 12 for environmental impact information.

7. HANDLING AND STORAGE

STORAGE TEMPERATURE (min./max.): ……………………………………. 40 F (4 C) / 90 F (32 C).

STORAGE: ……………………………………………………………………………… Store in cool, dry place away from high temperatures and moisture. Keep
container tightly closed. Store away from incompatible materials listed in Section 10. Store in a secure location with restricted access or store
locked up.

HANDLING PRECAUTIONS: …………………………………………………….. Use with adequate ventilation. Do not breathe vapors or mists from heated
material. Avoid exposure to concentrated vapors. Avoid all skin and eye contact. Wash hands thoroughly after handling. When mixed with
epoxy resin this product causes an exothermic reaction, which in large masses, can produce enough heat to damage or ignite surrounding
materials and emit fumes and vapors that vary widely in composition and toxicity.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

butyl rubber or natural rubber). Body protective clothing should be used as needed based on the task being performed and the potential for
exposure.

RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with an organic vapor cartridge, organic vapor cartridge + P100, or a multi-contaminant
cartridge, depending on specific workplace conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator
and cartridge based on ingredients listed in Section 3 and specific workplace conditions. Use and select a respirator according the guidelines
established in OSHA 1910.134 or other applicable respiratory protection standard.
