3. Hazards identification
Part I, Appearance and overview of significant concerns: Brown to black semi-tacky thin solid sheet, fabric
or yarn with faint epoxy odor. This material is made up of a resin component and an inert fiber component.
This product is electrically conductive. It may cause minor chemical or mechanical irritation of the eyes or
skin. This material is combustible. Store in a freezer (protected from moisture) for material integrity.
Part II, Adverse health effects and symptoms:
Carcinogenicity: None of the ingredients is listed as a carcinogen on IARC, NTP, or OSHA databases.
Primary Route(s) of entry: Dermal
Eyes: May cause eye irritation. The fiber component may cause mild, temporary mechanical eye irritation.
Skin: May cause skin irritation and dermatitis. The fiber component may cause mild, temporary mechanical
skin irritation.
4. First Aid Measures
Ingestion: If swallowed, immediately give at least 3-4 glasses of water, but do not induce vomiting. Do not
give anything by mouth to an unconscious or convulsing person, Get immediate medical attention. Have
physician determine whether vomiting or stomach evacuation is necessary.
Skin: For skin contact, wash affected areas with plenty of water, and soap, if available, for several minutes.
Remove and clean contaminated clothing and shoes before re-use. Get medical attention if irritation occurs.
Inhalation: If inhaled, remove from area to fresh air. Get medical attention if respiratory irritation develops
or if breathing becomes difficult.
Eyes: For eye contact, immediately flush eyes for at least 15 minutes with running water. Hold eyelids
apart to ensure rinsing of the entire eye surface and lids with water. Remove contact lenses to ensure
thorough flushing. Get immediate medical attention.

5. Fire Fighting
Warning ! This product is electrically conductive.
Flash Point: > 200篎
Flash Point Method Used: PMCC
Fire Fighting Extinguishing Media: Use carbon dioxide or dry chemical for small fires; aqueous foam or
water for large fires.
Fire Fighting Equipment: Use self-contained breathing apparatus and full protective clothing.
Fire and Explosion Hazards: Closed containers may rupture (due to buildup of pressure) when exposed to
extreme heat.
6. Accidental Release Measures
This material is normally supplied in small qualities and is semi-solid sheet, fabric or yarn material at room
temperatures. If spilled when resin is warmed to a liquid state, absorb onto sand or other absorbent
material. Shovel into closable container for disposal. Scrape, flush and scrub residue well with detergent.
Do not flush residue into sewers discharging directly into domestic water systems or natural waterways.
7. Handling and storage
Handling: Avoid contact with eyes, skin and clothing. Avoid breathing vapor, mist or spray. Use only
with good ventilation. Individuals should wash thoroughly after handling. For industrial use only.
Storage: Store in a freezer at 40篎 or colder for prolonged periods (protect from moisture). May be stored at
room temperature for a few weeks with only minor degradation. DO NOT STORE under warm or hot
conditions. NEVER let storage temperatures exceed 160篎.
8. Exposure controls and personal protection
Mechanical ventilation and local exhaust is recommended if resin is heated above 160篎.
Wear gloves and goggles to prevent skin and eye contact.
9. Physical and chemical properties
Color Brownish-black
Physical state Resin coated sheet,
fabric goods, or yarn
Solubility in water Not determined
Vapor pressure Not applicable
Specific gravity 1.2 (H2O = 1)
Boiling point Not establised
Percent Volatile < 2%
10. Stability and reactivity
Stability: Stable at 40篎 and colder. Degrades slowly at room temperature.
Conditions to avoid: Storage temperatures above 160篎.
Incompatibility: Strong alkali, acids.
Hazardous decomposition products: CO/CO2, phenol, unknown hydrocarbons, nitrogen oxides.
Hazardous polymerization: This material is pre-catalyzed. The rate of reaction is temperature dependent.

11. Toxicological information
Not determined.
12. Ecological information
No ecological information is available.
13. Disposal considerations
Un-polymerized resin should be disposed of as hazardous waste. Package in small quantities to avoid
un-controlled exothermic reaction. Follow federal, state and local regulations. Fully polymerized resin may
be disposed of as ordinary solid waste.
