Section IV – Fire and Explosion

Flash Point:  See Section X.

Flammable Limits:  .8% - 13%

Extinguishing Media:  Water Spray (for containment), Foam, Carbon Dioxide, Dry Chemical.

Special Fire Fighting Procedures:  
Full protective equipment, including self-contained breathing apparatus, is recommended.  Water from fogging, nozzles may be used to cool closed containers to prevent pressure build up preventing rupturing.  Do not use direct water stream on combustible or flammable liquid fires.

Unusual fire and explosion hazards:  
When heated above the defined flash points these solvents emit flammable vapors which, when mixed with air, can burn or be explosive when exposed to any ignition source.  Fine mists or spray may be flammable at temperatures below the flash point.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Section V – Health Hazard Data
General Effects:
Ingestion:  Gastrointestinal distress.  In the unlikely event of ingestion call a physician immediately and have the names and ingredients available.

Inhalation:  May cause nose and throat irritation.  Repeated and prolonged overexposure to solvents may lead to permanent brain and nervous system damage.  Eye watering, headaches, nausea, dizziness and loss of coordination are signs that solvent levels are too high.  Exposure to isocyanates may cause respiratory sensitization.  This effect may be delayed for several hours after exposure.  Repeated overexposure to isocyanates may cause a decrease in lung function which may be permanent.  Individuals with breathing problems or prior reaction to isocyanates must not be exposed to vapors or spray mist of this product.  If affected by inhalation of vapor or spray mist, remove to fresh air.  If breathing difficulty persists, or occurs later, consult a physician.

Skin or Eye Contact:  May cause irritation or burning of the eyes.  Repeated or prolonged liquid contact may cause skin irritation with discomfort and dermatitis.  In case of eye contact, immediately flush with plenty of water for at least 15 minutes;  call a physician.  In case of skin contact, wash with soap and water.  If irritation occurs, contact a physician.

Specific Effects:
Aliphatic Poly Isocyanate Resin, Hexamethylene Diisocyanate, and Isophorone Diisocyanate Resin:  Repeated exposure may cause allergic skin rash, itching, swelling.  May cause eye irritation with discomfort, tearing, or blurred vision.  Repeated overexposure to isocyanates may cause lung injury, including a decrease in lung function, which may be permanent.  Overexposure may cause asthma-like reactions with shortness of breath, wheezing, cough, which may be permanent; or permanent lung sensitization.  This effect may be delayed for several hours after exposure.  Individuals with preexisting lung disease, asthma or breathing difficulties may have increased susceptibility to the toxicity of excessive exposures.  

Butyl Acetate:  May cause abnormal liver function.

Ethylbenzene:  (Contributed from Xylene) – moderate toxicity by irritation to the skin, eyes, mucous membranes and by ingestion and inhalation routes.  The International Agency for Research on Cancer (IARC) has evaluated ethylbenzene and classified it as a possible human carcinogen (Group 2B) based on sufficient evidence for carcinogenicity in experimental aniamals, but inadequate evidence for cancer in exposed humans.

Methyl Isobutyl Ketone:  Recurrent overexposure may result in liver and kidney damage.

Toluene:  Continuous recurrent overexposure may cause liver or kidney damage.  High airborne levels have produced irregular heart beats in animals and occasional palpitations in humans.  Rats exposed to high airborne levels have exhibited high frequency hearing deficits.  Warning:  This chemical is known to the state of California to cause birth defects or other reproductive harm.

Xylene:  High concentrations have caused embryo toxic effects in laboratory animals.  Continuous recurrent over exposure may cause liver or kidney damage.  Can be absorbed through the skin in harmful amounts.

Section VI – Reactivity Data
Stability:  Stable

Incompatibility (Materials to avoid):  None reasonably foreseeable.

Hazardous Decomposition Products:  CO, CO2, Smoke.

Hazardous Polymerization:  Will not occur.
----------------------------------------------------------------------------------------------------------------------------------------------
Section VII – Spill or Leak Procedures

Steps to be taken in case material is released or spilled:  Do not breathe vapors.  Do not get in eyes or in skin.  Wear a positive pressure supplied air vapor/particulate respirator (NIOSH/MSHA TC-19C), eye protection, gloves  and protective material.  Remove sources of ignition.  Absorb with inert material.  Ventilate area.

Waste Disposal Method:  Do not allow material to contaminate ground water systems.  Incinerate absorbed material in accordance with federal, state, and local requirements.  Do not incinerate in closed containers.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Section VIII – Special Protection Information

Respiratory:  Do not breathe vapors or mists.  Wear a positive pressure supplied air respirator (NIOSH/MSHA (TC-19C) while mixing activator with any paint or clear enamel, during application and until all vapors and spray mists are exhausted.  Individuals with a history of lung or breathing problems or prior reaction to isocyanate should not use or be exposed to this product.  Do not permit anyone without protection in the painting area.  Follow the respirator manufacturer’s directions for respirator’s use.

Ventilation:  Provide sufficient ventilation in volume and pattern to keep contaminants below applicable OSHA requirements.

Protective Clothing:  Neoprene gloves and coveralls are recommended.

Eye Protection:  Desirable in all industrial situations.  Include splashguards or side shields.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Section IX – Special Precautions

Precautions to be taken in handling and storing:  Observe label precautions.  Keep away from heat, sparks and flame.  Close container after each use.  Ground containers when pouring. Wash thoroughly after handling and before eating and smoking.  Do not store above 120 F.

Other Precautions:  Do not sand, flame cut, braze or weld dry coating without a NIOSH/MSHA approved respirator or appropriate ventilation.
