rupturing closed containers.
Hazardous Combustion Products
Thermal oxidative decomposition may produce irritating and toxic fumes.
Upon decomposition, this product emits carbon monoxide, carbon dioxide and/or low molecular weight
hydrocarbons. Hydrogen cyanide, nitrogen oxides and isocyanates may be released.
Extinguishing Media
Dry chemical, foam, carbon dioxide, water fog. Avoid direct contact of this product with water since this can cause
a violent exothermic reaction. Use water to cool fire-exposed containers and to protect personnel.
Fire Fighting Equipment/Instructions
Firefighters should wear full protective equipment including self-contained positive pressure breathing apparatus
with full facepiece.

* * * Section 6 - Accidental Release Measures * * *
Containment Procedures
Prevent runoff into sewers, storm drains, surface waters and soil. Isolate the spill and ventilate the area. Confine
and contain small spills using inert materials (e.g. paper towels, spill control pillows, absorbent materials
Clean-Up Procedures
Wear appropriate protective equipment and clothing during clean-up. Absorb spill with inert material such as
vermiculite, sawdust, dirt, clay, cob grit, sand, or Millisorb? Shovel material into approved waste container and
dispose of all material in accordance with applicable regulations on waste disposal. Decontaminate the spill area.
In addition, comply with all applicable regulations on spill reporting.
Evacuation Procedures
Isolate area. Keep unnecessary personnel away.
Special Procedures
Regulations vary. Clean up and dispose of waste in accordance with all federal, state, and local environmental
regulations.

* * * Section 7 - Handling and Storage * * *
Handling Procedures
Do not breath vapors or mists of this product. Do not get this material in your eyes, on your skin, or on your
clothing. Wash thoroughly after handling. Use only with adequate ventilation. If container is exposed to high heat
or contaminated with moisture, it can be pressurized and possibly rupture. The isocyanate found in this product
reacts slowly with water to form CO2 gas, which can cause sealed containers to expand and possibly rupture.
Storage Procedures
Store in a cool, dry, well-ventilated area. Manufacturer recommends storing between 75 - 105 篎 (24 - 41 篊).
Store in tightly closed containers to prevent moisture contamination. Do not reseal if contamination is suspected.

Material Safety Data Sheet
Material Name: PC?88 Adhesive Component II ID: PC-014
Chemical Stability: Conditions to Avoid
Avoid heat, contact with water and other incompatible materials.
Incompatibility
Incompatible with amines, ammonia, strong acids and bases, alcohols, oxidizing agents. Reacts with water to
generate carbon dioxide and heat. Avoid contact with metals such as: zinc, copper, brass, aluminum, and
galvanized metals. Avoid unintended contact with polyols.
Hazardous Decomposition
Hazardous decomposition products may include carbon dioxide, carbon monoxide, oxides of nitrogen, hydrogen
cyanide gas, and isocyanate vapors.
Hazardous Polymerization
Hazardous polymerization may occur; contact with moisture or other materials which react with isocyanates may
cause polymerization. At temperatures >400 篎 (>204 篊) isocyantes can polymerize and decompose potentially
rupturing closed containers. Polymerization may be catalyzed by strong bases and water.
* * * Section 11 - Toxicological Information * * *
Acute and Chronic Toxicity
A: General Product Information
Exposure to isocyanate vapors or mists at concentrations above the TLV can irritate the mucous membranes in
the respiratory tract causing runny nose, sore throat, coughing, chest discomfort, shortness of breath and reduced
lung function. Skin contact may cause an allergic skin sensitization reaction characterized by redness, swelling,
rash, scaling and blistering. Once sensitized, an individual may react even to airborne levels below the exposure
limit with itching and tingling of the earlobes and neck, rash, hives, swelling of the arms and legs or other
symptoms common to allergic dermatitis. Persons with a pre-existing, nonspecific bronchial hyperreactivity can
respond to concentrations below the TLV with similar symptoms as well as asthma attack. Chemical or
hypersensitive pneumonitis with flu-like symptoms has also been reported. These symptoms can be delayed up
to several hours after exposure.
As a result of previous repeated overexposures or a single large dose, certain individuals develop isocyanate
sensitization (chemical asthma) which will cause them to react to a later exposure to isocyanate at levels well
below the TLV. These symptoms, which can include chest tightness, wheezing, cough, shortness of breath or
asthma attack could be immediate or delayed (up to several hours after exposure). Similar to many non-specific
asthmatic responses, there are reports that once sensitized an individual can experience these symptoms upon
exposure to dust, cold air, or other irritants. Overexposure to isocyantes has been reported to cause lung
damage, which may be permanent. The sensitization can either be temporary or permanent.
