PRIMARY ROUTE(S) OF ENTRY:............................ Skin contact, eye contact, inhalation.
POTENTIAL HEALTH EFFECTS:
ACUTE INHALATION: .............................................. Exposure to high concentrations of vapor causes
irritation to the respiratory tract.

EYE CONTACT: ........................................................ Moderate to severe irritation. Causes severe irritation,
pain and possible permanent injury.
INGESTION: .............................................................. Severely irritating to gastrointestinal system. May be an
aspiration hazard.
SYMPTOMS OF OVEREXPOSURE: ........................ Development of allergic reaction or sensitization. Skin
irritation and redness.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Chronic respiratory disease (e.g., bronchitis, asthma). Skin conditions and allergies.
4. FIRST AID MEASURES:
FIRST AID FOR EYES: ............................................. Immediately flush with water for at least 15 minutes. Get
prompt medical attention.
FIRST AID FOR SKIN: .............................................. Remove contaminated clothing. Immediately wash skin
with soap and water. Do not apply greases or ointments. Get medical attention if wide spread exposure.
FIRST AID FOR INHALATION: ................................ If symptoms occur as noted in Section 3, remove to
fresh air. Get medical attention if symptoms persist or worsen.
FIRST AID FOR INGESTION:................................... Give conscious person at least 2 glasses of water. Do
not induce vomiting. If vomiting should occur spontaneously, keep airway clear. Get medical attention.
5. FIRE FIGHTING MEASURES:
FLASH POINT: .......................................................... > 200癋 (PMCC)
EXTINGUISHING MEDIA: ......................................... Water spray, dry chemical, alcohol foam and carbon
dioxide (CO2).
FIRE AND EXPLOSION HAZARDS: ........................ Burning will generate toxic fumes. When mixed with
sawdust, wood chips, or other cellulosic material, spontaneous combustion can occur under certain
conditions. If hardener is spilled into or mixed with sawdust, 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. If spill has ignited, use water spray to disperse vapors and protect personnel attempting
to stop leak. Use water to cool fire-exposed containers.
6. ACCIDENTAL RELEASE MEASURES:
SPILL OR LEAK PROCEDURES: Stop leak without causing additional risk. Wear proper personal
protective equipment. Contain spill and ventilate area. Large or small spill - scoop bulk into appropriate
container for recovery. Use inert, non-combustible absorbent material (e.g., sand) and shovel remainder into
suitable container for disposal. Do not use sawdust, wood chips or other cellulosic materials to absorb the
spill, as the possibility for spontaneous combustion exists. Wash spill residue with warm, soapy water if
necessary.
7. HANDLING AND STORAGE:
STORAGE TEMPERATURE (min./max.): ............... 40癋 (4癈) / 90癋 (32癈)

SHELF LIFE: ............................................................. Reference product label.
STORAGE: ................................................................ Minimum feasible handling temperatures should be
maintained. If stored above 100癋, nitrogen atmosphere is recommended. Keep containers tightly closed.
HANDLING PRECAUTIONS:.................................... Use with adequate ventilation. Do not breathe vapors or
mists from heated material. Avoid contact with skin and eyes. 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.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION:
EYE PROTECTION GUIDELINES: ........................... A minimum of safety glasses with side shields.
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:
General mechanical or local exhaust ventilation. In the absence of adequate ventilation, use a NIOSH
approved air purifying respirator with an organic vapor cartridge.
ADDITIONAL PROTECTIVE MEASURES: .............. Use where there is immediate access to safety shower
and emergency eye wash. Provide proper wash/cleanup facilities for proper hygiene. Contact lens should not
be worn when working with this material.
OCCUPATIONAL EXPOSURE LIMITS: ................... Not established for product as whole. Refer to OSHA's
Permissible Exposure Level (PEL) or the ACGIH Guidelines for information on specific ingredients.

VAPOR DENSITY...................................................... Heavier than air.
% VOLATILE BY WEIGHT........................................ EPA Method 24, as described in 40 CFR Part 60, was
used to determine the Volatile Matter Content of mixed epoxy resin and hardener. This method states that
two-component coating systems should be tested by determining weight loss after mixing the individual
components together at the proper ratio, dissolving them in an appropriate solvent, and subjecting them to a
temperature of 230癋. 650 Resin and 650 Hardener, mixed together at 1.2:1 by weight, has a density of 1050
g/L (8.76 lbs/gal). The combined VOC content for 650 Resin/650 Hardener is 7.7 g/L (0.06 lbs/gal).
