REACTIVITY DATA
________________________________________________________________

STABILITY (CONDITIONS TO AVOID):

None; but for maximum product life do not exceed 55oC (131oF)
during storage.

INCOMPATIBILITY (SPECIFIC MATERIALS TO AVOID):

Base or strong acid, amines and oxidizing materials.

HAZARDOUS DECOMPOSITION PRODUCTS:

The by-products expected in incomplete pyrolysis or
combustion of epoxy resins are mainly phenolics, carbon
monoxide, hydrogen chloride, and water. The thermal
decomposition products of epoxy resins therefore should
be treated as potentially hazardous substances, and
appropriate precautions should be taken.

HAZARDOUS POLYMERIZATION:

Will not occur by itself, but masses of more than 1 pound
of product plus an aliphatic amine will cause irreversible
polymerization with considerable heat buildup.

ENVIRONMENTAL AND DISPOSAL INFORMATION
________________________________________________________________

ACTION TO TAKE FOR SPILLS/LEAKS:

Soak up in absorbent material such as sand and collect in suitable
containers. Residual resin may be removed using steam or hot soapy
water. Solvents are not recommended for cleanup unless the recommended
exposure guidelines and safe handling practices for the specific
solvent are followed. Consult appropriate solvent MSDS for handling
information and exposure guidelines. Keep spark producing equipment
away. For large spills, evacuate upwind of spills and contain
with dike.

DISPOSAL METHOD:

DO NOT DUMP INTO ANY SEWERS, ON THE GROUND, OR INTO ANY BODY OF
WATER. For unused or uncontaminated material, the preferred disposal
options are to send to a licensed recycler, reclaimer, or incinerator.
For used or contaminated material, the preferred
disposal options remain the same, although additional evaluation
is required (see, for example, 40 CFR, Part 261, "Identification
and Listing of Hazardous waste.") Any disposal practice must be
in compliance with Federal, State, Provincial, and Local laws and
regulations.

HEALTH HAZARD DATA
________________________________________________________________

EYE: May cause moderate irritation with corneal injury.

SKIN CONTACT:

Short single exposure not likely to cause significant skin irritation.
Prolonged exposure may cause skin irritation. Repeated exposure
may cause skin burns. May cause more severe
response if confined to skin or skin is abraded (scratched or 
cut). May cause allergic skin reaction in susceptible individuals.

SKIN ABSORPTION:

A single prolonged exposure is not likely to result in
the material being absorbed through skin in harmful
amounts. The LD50 for skin absorption in rabbits is >2000mg/kg.

INGESTION:

Single dose oral toxicity is low. The oral LD50 for
rats is >2000 mg/kg. Amounts ingested incidental to
normal handling operations are not likely to cause injury;
swallowing larger amounts may cause injury.

INHALATION:

Elevated temperatures may generate vapor levels 
sufficient to cause irritation and other effects.

MUTAGENICITY (EFFECTS ON GENETIC MATERIAL):

Results of in vitro ("test tube") mutagenicity tests
have been positive.
________________________________________________________________

FIRST AID
________________________________________________________________

EYES: Irrigate immediately with water for at least 15 minutes.

SKIN: Wash off in flowing water or shower.

INGESTION:

Induce vomiting if large amounts are ingested. Consult medical
personnel.

INHALATION:

Remove to fresh air if effects occur. Consult a physician.

NOTE TO PHYSICIAN:

If burn is present, treat as any thermal burn, after
decontamination. No specific antidote. Supportive care.
Treatment based on judgement of the physician in response
to reactions of the patient.

HANDLING PRECAUTIONS
________________________________________________________________

EXPOSURE GUIDELINE(S): None established.

VENTILATION:

Good general ventilation should be sufficient for most
conditions.

RESPIRATORY PROTECTION:

No respiratory protection should be needed. If respiratory
irritation is experienced, use an approved air-purifying
respirator.

SKIN PROTECTION:

For brief contact, no precautions other than clean body-
covering clothing should be needed. When prolonged or
frequently repeated contact could occur, use protective
clothing impervious to this material. Selection of
specific items such as gloves, boots, apron or full-body
suit will depend on operation.

EYE PROTECTION:

Use safety glasses. Where contact with this material is
likely, chemical goggles are recommended because eye contact may
cause pain even though it is unlikely to cause injury.

SPECIAL PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE:

None except normal handling care. Practice good caution
and personal cleanliness to avoid eye and skin contact.
Avoid breathing vapors if generated.
