normal conditions of use. Seek medical attention if a significant amount is ingested.

5. FIRE FIGHTING MEASURES:

FLASH POINT: ............................................................................... >200癋 (Tag Closed Cup)

EXTINGUISHING MEDIA: .............................................................. Foam, carbon dioxide (CO2), dry chemical.

SPECIAL FIRE FIGHTING PROCEDURES:
Wear a self-contained breathing apparatus and complete full-body personal protective equipment. Closed containers may rupture (due to
buildup of pressure) when exposed to extreme heat.

FIRE AND EXPLOSION HAZARDS:.............................................. HAZARDOUS DECOMPOSITION PRODUCTS: 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: phenolics, carbon monoxide, carbon.

6. ACCIDENTAL RELEASE MEASURES:

SPILL OR LEAK PROCEDURES .................................................. Soak up in absorbent material or scrape up. Residual can be removed
with non-flammable solvent, but solvent should be used sparingly and with appropriate precautions.

7. HANDLING AND STORAGE:

STORAGE TEMPERATURE (MIN./MAX): ..................................... 40癋 (4癈) / 120癋 (49癈)

SHELF LIFE: .................................................................................. Reference product label.

STORAGE: ..................................................................................... Store in cool, dry place. Store in tightly sealed containers to prevent
moisture absorption and loss of volatiles. Excessive heat over long periods of time will degrade the resin.

HANDLING PRECAUTIONS: ......................................................... Avoid prolonged or repeated skin contact. Wash thoroughly after
handling. Launder contaminated clothing before reuse. Avoid inhalation of vapors from heated product. Precautionary steps should be
taken when curing product in large quantities. When mixed with epoxy curing agents this product causes an exothermic, 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: ................................................ Safety glasses with side shields or chemical splash goggles.

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:
Good room ventilation is usually adequate for most operations. Wear a NIOSH/MSHA approved respirator with an organic vapor
cartridge whenever exposure to vapor in concentrations above applicable limits is likely.

Note: Pro-Set, Inc.. has conducted an air sampling study using this product or similarly formulated products. The results indicate that the
components sampled for (epichlorohydrin, ethylene glycol monobutyl ether) were either so low that they were not detected at all or they
were well below OSHA's permissible exposure levels.

ADDITIONAL PROTECTIVE MEASURES:.................................... Practice good caution and personal cleanliness to avoid skin and eye
contact. Avoid skin contact when removing gloves and other protective equipment. Wash thoroughly after handling. 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: ........................................ Not established for product as whole. Refer to OSHA's Permissible
Exposure Level (PEL) or the ACGIH Guidelines for information on specific ingredients.

11. TOXICOLOGICAL INFORMATION:

No specific oral, inhalation or dermal toxicology data is known for this product. Specific toxicology information for a bisphenol-A
based epoxy resin present in this product is indicated below:

Oral: ................................................................ LD50 > 5000 mg/kg (rats)
Inhalation: ....................................................... No Data.
Dermal: ........................................................... LD50 = 20,000 mg/kg (skin absorption in rabbits)

TERATOLOGY:............................................................................... Ethylene glycol monobutyl ether (present at < 0.5 %) causes harm to
the fetus in laboratory animal studies. Harm to the fetus occurs at exposure levels that harm the pregnant animal. The relevance of
these findings to humans is uncertain.

MUTAGENICITY: ............................................................................ Neopentyl glycol diglycidyl ether has been reported to be mutagenic in
some laboratory tests.

CARCINOGENICITY:
NTP......................................................................................... Product not listed.
IARC ....................................................................................... Product not listed.
OSHA...................................................................................... Product not listed.

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
DGEBPA is carcinogenic. Indeed, the most recent review of the available data by the International Agency for Research on Cancer
(IARC) has concluded that DGEBPA is not classified as a carcinogen.

Epichlorohydrin, an impurity in this product (<25 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.


Neopentyl glycol diglycidyl ether has been reported to be carcinogenic in some laboratory tests.
