MUTAGENICITY: …………………………………………………………………….. Not classified. Based on available data does not meet criteria for germ cell
mutagenicity.
Diglycidyl ether bisphenol-A in animal mutagenicity studies were negative. In vitro mutagenicity tests were negative in some cases and positive in
others.
CARCINOGENICITY: ……………………………………………………………….. Not classified. Based on available data does not meet criteria for
carcinogenicity.
Many studies have been conducted to assess the potential carcinogenicity of diglycidyl ether of bisphenol-A. Although some weak evidence of
carcinogenicity has been reported in animals, when all of the data are considered, the weight of evidence does not show that Diglycidyl ether
bisphenol-A is carcinogenic. Indeed, the most recent review of the available data by the International Agency for Research on Cancer (IARC) has
concluded that Diglycidyl ether bisphenol-A is not classified as a carcinogen.
Epichlorohydrin, an impurity in this product (<5 ppm) has been reported to produce cancer in laboratory animals and to produce mutagenic
changes in bacteria and cultured human cells. It has been established by the International Agency for Research on Cancer (IARC) as a probable
human carcinogen (Group 2A) based on the following conclusions: human evidence inadequate; animal evidence sufficient. It has been
classified as an anticipated human carcinogen by the National Toxicology Program (NTP). Note: It is unlikely that normal use of this product
would result in measurable exposure concentrations to this substance.

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.

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

Page 3 of 7 Last Revised: 20JAN23
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

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
Entropy Resins
High Bio-based Fast Laminating Hardener
Page 3 of 7 Last Revised: 20JAN23
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.

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
Entropy Resins
High Bio-based Fast Laminating Hardener
Page 3 of 7 Last Revised: 20JAN23
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.
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. 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.

STABILITY: ......................................................................................... Product is stable at normal temperatures and pressures.
REACTIVITY/HAZARDOUS REACTIONS : ......................................... Product will not react by itself under normal operating temperatures. A
mass of more than one pound of product plus an epoxy resin will cause irreversible polymerization with significant heat buildup and pressure.
INCOMPATIBILITIES: ......................................................................... Avoid acids, oxidizing materials, halogenated organic compounds (e.g.,
methylene chloride). External heating or self-heating could result in rapid temperature increase and pressure build up. If such a condition were to
occur in a drum, the drum could expand and rupture violently.
CONDITIONS TO AVOID: ................................................................... Avoid excessive heat and direct sunlight.
DECOMPOSITION PRODUCTS: ......................................................... Very toxic fumes and gases when burned or otherwise heated to thermal
decomposition. Decomposition products may include, but not limited to: oxides of nitrogen, volatile amines, ammonia, nitric acid.
