The exact chemical identity and/or exact percentage (concentration) of each ingredient may be held as confidential business information
(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: Toxic in contact with skin. Causes severe 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: Fatal if inhaled. Can cause respiratory irritation, shortness of
breath or cough. Effects can be immediate or delayed. In the case of inhalation of thermal decomposition products, the exposed person may need
to be kept under medical surveillance for 48 hours. RESPONSE: Remove to fresh air if effects occur and keep comfortable for breathing.
Immediately call a POISON CONTROL CENTER or doctor.
FIRST AID FOR INGESTION …………………………………………………….. SYMPTOMS: May cause gastrointestinal irritation or ulceration. May
cause burns of the mouth and throat. If vomiting occurs, the head should be kept low to prevent vomitus from entering lungs. 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. 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, untrained, 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, limestone powder) 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. Store in
a well-ventilated area, away from incompatible materials listed in Section 10. Keep container tightly closed. Store in a secure location with
restricted access or store locked up.
HANDLING PRECAUTIONS: ……………………………………………………. Use only with adequate ventilation or respiratory protection. Use PPE as
described in Section 8. Do not breathe vapors, aerosols or mists from material. Prevent all 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 damage or ignite
surrounding materials and emit fumes and vapors that vary widely in composition and toxicity. Do not breathe vapors or fumes from uncontrolled
exotherming masses.
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, butyl
rubber or ethyl vinyl alcohol laminate EVAL) and full body protective clothing. Consider the parameters specified by the glove manufacturer and
check during use to ensure that gloves are still retaining their protective properties.
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
established exposure limits of specific ingredients in this product, or other available exposure limit information, refer to the table below.

oxidizing materials, halogenated organic compounds (e.g., methylene chloride), nitrosating agents, sodium hyprochlorite, acid chlorides and acid
anhydrides. 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. Can have corrosive effects on some metals.
CONDITIONS TO AVOID: .................................................................. Avoid excessive heat.
