SECTION 1 - MATERIAL IDENTIFICATION AND INFORMATION
INGREDIENT/CAS # EXPOSURE LIMITS
Chemical Name: Polymeric MDI and Plasticizer ACGIH TLV 0.005 ppm TWA
Hazardous Ingredients/OSHA: Methylene bis(phenylisocyanate) (MDI), CAS# 101-68-8, OSHA PEL 0.02 ppm (Ceiling)
and other isomers.
Other ingredients are a trade secret mixture of substances for which no applicable exposure limits have been established by OSHA or
ACGIH.
SECTION 2 - PHYSICAL / CHEMICAL CHARACTERISTICS
Appearance and odor: Brown clear liquid, mild odor.
Specific Gravity, at 25鈥? C, g/cc: Approximately 1.1.
Solubility in Water: Insoluble, forms CO2
Boiling Point (鈥? F): No data.
Vapor Pressure: Negligible.
SECTION 3 - FIRE AND EXPLOSION HAZARD DATA
Flash Point: 400鈥? F, (estimated).
Extinguishing Media: Carbon dioxide, dry chemical, foams, or water fog or fine spray.
Hazardous Combustion Products : May include MDI vapor, nitrogen oxides, isocyanates, carbon monoxide, carbon dioxide, and
unidentified toxic and irritating compounds..
Other Information: Firefighters wear SCBA and full-body protective suit. Solid stream of water into hot product may
cause violent steam generation or eruption. Dense smoke is formed when product burns. Use water
to cool hot containers.
SECTION 4 - REACTIVITY HAZARD DATA
Conditions to Avoid: Moisture and temperatures <75 掳F and >95掳F to ensure product integrity.
Incompatibility with other materials: Avoid contact with water, acids, bases, alcohols, strong oxidizers, and some metals (e.g.,
aluminum, brass, copper). Reaction with water generates carbon dioxide, and results in
heat and pressure buildup in closed systems.
Hazardous Decomposition Products: Possibly isocyanate vapor, carbon monoxide, nitrogen oxides, and traces of hydrogen
cyanide.
SECTION 5 - HEALTH HAZARD DATA
Primary Route(s) of Entry:Inhalation, skin or eye absorption.
Eye: May cause moderate eye irritation.
Skin: Exposure may cause skin irritation, staining, or sensitization.
Ingestion: Single oral dose toxicity is low. May cause nausea, vomiting, and diarrhea.
Inhalation: At room temp., vapors are minimal. Vapors or aerosols (e.g., generated during heating or spraying)
may cause respiratory irritation. May cause respiratory sensitization in susceptible individuals. For
individuals sensitized to MDI, exposure may result in allergic respiratory reactions (e.g., coughing,
difficulty breathing).
Chronic Effects: Repeated overexposure to MDI may cause respiratory and dermal sensitization. Long-term
overexposure to MDI may result in impaired lung function.
Carcinogenicity: Rats exposed to MDI aerosol for their lifetime developed lung tumors.
Emergency and First Aid Procedures: Eye Contact: Flush with water immediately for 15 minutes. Seek medical attention.
Skin Contact: Wash with soap and plenty of water (preferably warm water).
Inhalation: Remove to fresh air. Treat symptomatically. Seek medical attention.
Ingestion: Seek medical attention. Do not induce vomiting unless so directed by a
physician.
SECTION 6 - PRECAUTIONS FOR SAFE HANDLING AND USE
Handling: Avoid breathing vapor. Use in well ventilated area. Avoid contact with eyes, skin and clothing. Do not eat, drink or
smoke in work area. Wash hands after handling. See Section 8.
Storage: Store indoors at temperatures >75掳F and <105掳F. Store in original, unopened container. Protect from atmospheric
moisture and water, since MDI reacts with water to form CO2 leading to potentially dangerous pressure build up in
sealed containers.
SECTION 7 - SPILL AND DISPOSAL MEASURES
Clear non-emergency personnel from the area. Extinguish sources of ignition. Put on protective equipment (see Section 8). Contain spill
to minimize environmental contamination. Absorb spilled material with an inert absorbent. Collect and containerize material. Do not seal
containers of spill residue since carbon dioxide is generated upon contact with moisture and dangerous pressure buildup can occur.
Neutralize contaminated floor area with a mixture of water (90%), ammonia (3-8%) and detergent (2%). Clean floor before material reacts
with moisture in the air and forms a difficult to remove rubber.
SECTION 8 - PROTECTION AND CONTROL MEASURES
LIQUACASTA-2
Engineering Controls: Provide general and/or local exhaust to maintain airborne concentrations below exposure limits (see
Section 1 for exposure limits).
Personal Protective Equipment: Chemical splash goggles, protective clothing, and impervious rubber gloves are recommended.
Respiratory Protection: In the absence of good ventilation, use a supplied-air respirator, or, if unavailable, a respirator
equipped with organic vapor cartridges. In emergencies, use SCBA.
SECTION 9 - REGULATORY AND OTHER INFORMATION
Sara Section 313: This product contains the following Section 313 ingredient:
