Methylenebiscyclohexanamine, 4,4 – 1761-71-3 70-100

The exact chemical identity and/or exact percentage (concentration) of each ingredient has been held as confidential business information (CBI).
Refer to Section 15 for additional information regarding this CBI claim.

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 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 CENTER or doctor.

FIRST AID FOR INHALATION…………………………………………………… SYMPTOMS: Can cause respiratory irritation, shortness of breath or cough.
RESPONSE: Remove to fresh air if effects occur and keep comfortable for breathing. Immediately contact physician if symptoms develop and
persist.

FIRST AID FOR INGESTION …………………………………………………….. SYMPTOMS: May cause gastrointestinal irritation or ulceration. May
cause burns of the mouth and throat. Aspiration hazard. Can enter the lungs and cause damage. RESPONSE: Rinse mouth with water. DO
NOT induce vomiting. If vomiting should occur, keep airway clear. Immediately call POISON 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, nitrosamines. 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

PERSONAL PRECAUTIONS AND PROTECTIVE EQUIPMENT: ……. 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, non-combustible 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 or non-flammable, safe solvent 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 storing near 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 skin 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. Do not breathe fumes generated from uncontrolled exothermic reaction.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

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/VENTILATION GUIDELINES: …………………………….. Use with adequate general ventilation and/or local ventilation to keep
exposures below established limits. 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
established exposure limits of specific ingredients in this product, or other available exposure limit information, refer to the table below.
