Section 3. Hazards Identification
WARNING! This product contains isocyanates that readily react with body moisture causing eye and skin irritation. May cause
allergic respiratory reaction. May cause skin sensitization and dermatitis. Avoid inhaling fumes.
Potential Health Effects Primary Routes of Exposure:
X Skin contact X Skin Absorption X Eye Contact X Inhalation X Ingestion
Routes of Exposure Symptoms
Inhalation of vapors can cause burning sensation in the respiratory tract with running nose, sore
Inhalation
throat, coughing chest discomfort and reduced lung function.
Can cause skin irritation such as blistering, swelling, redness and rashes.
Skin
Exposure to vapors and mist can cause irritation, pain, conjunctivitis and corneal edema.
Eyes
Harmful if swallowed. Can cause abdominal pain, nausea, vomiting and diarrhea.
Ingestion
Prolonged contact with skin can result in respiratory sensitization. Repeated inhalation exposure
Chronic
may cause lung damage and asthma.

MATERIAL SAFETY DATA SHEET
Carbon dioxide, dry chemical, foam.
Extinguishing Media
Isolate fire area and deny unnecessary entry.
Fire fighters should wear positive-pressure self-contained breathing apparatus
(SCBA) and protective clothing.
Unusual Fire and Explosions Hazards
Cool closed containers with WATER SPRAY to avoid explosion.
Heat from fire can generate vapor and decomposition products that may cause a
health hazard.
Section 6. Accidental Release Measures
ISOLATE AREA OF THE SPILL! Eliminate all ignition sources. Soak up small spills with inert solids such as vermiculite or
other absorbent materials. Shovel into suitable disposal container. Persons not wearing protective equipment should be excluded
from the area of spill until cleanup has been completed.
Section 7. Handling & Storage
Store material in a clean, cool, ventilated area away from all sources of ignition. Clean up spills at once. Keep container tightly
closed when not in use. This product reacts readily with moisture generating heat and gas. Avoid mixing with water. Always
wear protective equipment. Wash hands and other exposed areas thoroughly after handling.
Provide appropriate ventilation/respiratory protection against nuisance dust during sanding/grinding of cured product.
Section 8. Exposure Controls/Personal Exposure
Avoid splashing. Wear chemical-resistant safety goggles or face shield. Contact
Eye Protection
lenses must not be worn.
Chemical resistant synthetic rubber (neoprene, nitrile) gloves and other
protective clothing are recommended to prevent repeated or prolonged skin

contact.
If personal exposure cannot be controlled below applicable limits by area
ventilation, wear a properly fitted organic vapor/particulate respirator approved
Respiratory Protection
by NIOSH/MSHA for protection against materials in section 2.
General area ventilation is acceptable if the exposure is maintained below
applicable exposure limits. (See Section 2) Local exhaust is recommended for
