3) HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
CAUTION! Contents under pressure.
Vapors reduce oxygen available for breathing and are heavier than air.
May cause moderate eye irritation.
Sprayed or heated material harmful if inhaled. May cause allergic skin reaction. May
cause allergic respiratory reaction and lung injury. Avoid temperatures above 105F
(41C). Toxic flammable gases and heat are released under decomposition conditions.
Toxic fumes may be released in fire situations. Reacts slowly with water, releasing
carbon dioxide, which can cause pressure buildup and rupture of closed containers.
Elevated temperatures accelerate this process.
EYE
May cause moderate eye irritation. May cause very slight transient (temporary) corneal
injury.
SKIN
Prolonged or repeated exposure may cause slight skin irritation. May cause allergic
skin reaction in susceptible individuals. Animal studies have shown that skin contact
with isocyanates may play a role in respiratory sensitization. May stain skin. A
single prolonged exposure is not likely to result in the material being absorbed in
harmful amounts.
INGESTION
Single dose oral toxicity is considered to be low. No hazards anticipated from
swallowing small amounts incidental to normal handling operations.
INHALATION
At room temperature, vapors are minimal due to low vapor pressure. However, certain
operations may generate vapor or aerosol concentrations sufficient to cause irritation
or other adverse effects. Such operations include those in which the material is
heated, sprayed or otherwise mechanically dispersed such as drumming, venting or

MATERIAL SAFETY DATA SHEET
pumping. Excessive exposure may cause irritation to upper respiratory tract and lungs,
and pulmonary edema (fluid in the lungs). May cause respiratory sensitization in
susceptible individuals. MDI concentrations below the exposure guidelines may cause
allergic respiratory reactions in individuals already sensitized. Symptoms may include
coughing, difficult breathing and a feeling of tightness in the chest. Effects may be
delayed. Decreased lung function has been associated with overexposure to isocyanates.
SYSTEMIC EFFECTS
Tissue injury in the upper respiratory tract and lungs has been observed in laboratory
animals after repeated excessive exposures to MDI/polymeric MDI aerosols.
TERATOLOGY
In laboratory animals, MDI/polymeric MDI did not cause birth defects; other fetal
effects occurred only at high doses which were toxic to the mother.
CANCER INFORMATION
Lung tumors have been observed in laboratory animals exposed to aerosol droplets of
MDI/Polymeric MDI (6 mg/m3) for their lifetime. Tumors occurred concurrently with
respiratory irritation and lung injury. Current exposure guidelines are expected to
protect against these effects reported for MDI.

4) FIRST-AID MEASURES
EYE
Irrigate with flowing water immediately and continuously for 15 minutes. Remove
contacts after first five minutes and continue washing. Consult medical personnel.
SKIN
Remove material from skin immediately by washing with soap and plenty of water. Remove
contaminated clothing and shoes while washing. Seek medical attention if irritation
persists. An MDI skin decontamination study demonstrated that a polyglycol-based skin
cleanser or corn oil may be more effective than soap and water.
INGESTION
If swallowed, seek medical attention. Do not induce vomiting unless directed to do so
by medical personnel.
INHALATION
Remove to fresh air. If not breathing, give artificial respiration. If breathing is
difficult, oxygen should be administered by qualified personnel. Call a physician or
transport to a medical facility.
NOTE TO PHYSICIAN
No specific antidote. Provide supportive care. Treatment based on judgment of the
physician in response to reactions of the patient. May cause respiratory sensitization
or asthma-like symptoms. Bronchodilators, expectorants, and antitussives may be of
help. Respiratory symptoms, including pulmonary edema, may be delayed. Persons
receiving significant exposure should be observed for 24-48 hours for signs of
respiratory distress.

INSTA STIK* Quik Set Commercial Roof Adhesvie
GMID 279404

MATERIAL SAFETY DATA SHEET
During a fire, smoke may contain the original material in addition to unidentified
toxic and/or irritating compounds. Hazardous combustion products may include but are
not limited to: nitrogen oxides, isocyanates, hydrogen cyanide, carbon monoxide, and
carbon dioxide.
Additional combustion products may include ammonia, hydrocholoric acid, hydrofluoric
acid, chlorine, fluorine, phosgene and phosphorous oxides.
OTHER FLAMMABILITY INFORMATION
Product reacts with water. Reaction may produce heat and/or gases. Container may
rupture from gas generation in a fire situation. Violent steam generation or eruption
may occur upon application of direct water stream to hot liquids. Dense smoke is
produced when product burns. Spills of these organic liquids on hot fibrous insulations
may lead to lowering of the atoignition temperatures possibly resulting in spontaneous
combustion.
EXTINGUISHING MEDIA
Use carbon dioxide, dry chemical, foam, water fog or fine spray. Alcohol resistant
foams (ATC type) are preferred if available. General purpose synthetic foams
(including AFFF) or protein foams may function, but much less effective. Do not use
direct water stream which can spread fire.
FIRE FIGHTING INSTRUCTIONS
Keep people away. Isolate fire area and deny unnecessary entry. Stay upwind. Keep out
of low areas where gases (fumes) can accumulate. Water is not recommended but may be
applied in very large quantities as a fine spray when other extinguishing agents are
not available. Contain fire water run-off if possible. Do not use direct water stream.
May spread fire. Fight fire from protected location or safe distance. Consider use of
unmanned hose holder or monitor nozzles. Use water spray to cool fire exposed
containers and fire affected zone until fire is out. Immediately withdraw all
personnel from area in case of rising sound from venting safety devices or
discoloration of the containers. Move containers from fire area if this is possible
without hazard.
PROTECTIVE EQUIPMENT - FIRE FIGHTERS
Wear positive-pressure self-contained breathing apparatus (SCBA) and protective fire
fighting clothing (includes fire fighting helmet, coat, pants, boots, and gloves).
Avoid contact with this material during fire fighting operations. If contact is likely,
change to full chemical resistant clothing with SCBA. If his will not provide
sufficient fire protection; consider fighting fire from a remote location.

6) ACCIDENTAL RELEASE MEASURES
PROTECT PEOPLE
Avoid any contact. Barricade area. Clear non-emergency personnel from area. Keep upwind
of spill. Ventilate area of leak or spill. The area must be evacuated and reentered by
persons equipped for decontamination. Use appropriate safety equipment. If available,
use foam to suppress vapors.
PROTECT THE ENVIRONMENT
Contain liquid to prevent contamination of soil, surface water or ground water. Keep
out of ditches, sewers, and water supplies. Should the product enter sewers or drains,
it should be pumped into a covered, vented container; the cover should be placed
loosely on the container but not made pressure tight. Move to a well-ventilated area.
Emergency services may need to be called to assist in the cleanup operation.
CLEAN-UP
Supplies of suitable decontaminant should always be kept available. Absorb with
material such as: sawdust, vermiculite, dirt, sand, clay, cob grit, Milsorb. Avoid
materials such as cement powder. Collect material in suitable and properly labeled OPEN
containers. Do not place in sealed container. Prolonged contact with water results in a
chemical reaction which may result in rupture of the container. Place in: polylined

MATERIAL SAFETY DATA SHEET
fiber pacs, plastic drums, or properly labeled metal containers. Remove to a well
ventilated area. Clean up floor areas. Attempt to neutralize by suitable decontaminant
solution: Formulation 1: sodium carbonate 5-10%; liquid detergent 0.2-2%; water to make
up to 100%. OR Formulation 2: Concentrated ammonia solution 3-8%; liquid detergent
0.2-2%; water to make up to 100%. If ammonia is used, use good ventilation to prevent
vapor exposure. If you have any questions on how to neutralize call The Dow Chemical
Company.

7) HANDLING AND STORAGE
HANDLING
Avoid contact of this product with water at all times during handling and storage. Use
only with adequate ventilation. Keep equipment clean. Use disposable containers and
tools where possible. Do not eat, drink, or smoke in working area.
STORAGE
Store in a dry place. The recommended storage temperature is between 32 - 90F (0-32C).
Keep containers tightly closed when not in use. Protect containers from physical
abuse. Avoid direct sunlight. DO NOT incinerate aerosol can.

8) EXPOSURE CONTROL/PERSONAL PROTECTION
ENGINEERING CONTROLS
Use only with adequate ventilation. Provide general and/or local exhaust ventilation
to control airborne levels below the exposure guidelines. Exhaust systems should be
designed to move the air away from the source of vapor/aerosol generation and the
people working at this point. Odor is inadequate warning of excessive exposure.
EYE/FACE PROTECTION
Use chemical goggles.
SKIN PROTECTION
Use protective clothing impervious to this material. Selection of specific items such
as faceshield, gloves, boots, apron, or full-body suit will depend on operation.
Consideration of all chemicals involved, time and the dexterity needed to safely
complete the job must be considered. Solvents can significantly change the permeation
of a chemical through a barrier. Work with your safety equipment supplier to obtain
the best Personal Protective Equipment for the job. Nitrile gloves are often found to
be appropriate for work with MDI. Butyl rubber, PVC and neoprene are also often
chosen.


Remove contaminated clothing immediately, wash skin area with soap and water (warm
water if available) and launder clothing before reuse. Items which cannot be
decontaminated, such as shoes, belts and watchbands, should be removed and destroyed.
RESPIRATORY PROTECTION
Atmospheric levels should be maintained below the exposure guideline. When atmospheric
levels may exceed the exposure guideline, use an approved air-purifying respirator
equipped with an organic vapor sorbent and a particle filter. For situations where the
atmospheric levels may exceed the level for which an air-purifying respirator is
effective, use a positive-pressure air-supplying respirator (airline or self-contained
breathing apparatus). For emergency response or for situations where the atmospheric
level is unknown, use an approved positive-pressure self-contained breathing apparatus.
EXPOSURE GUIDELINES(S)
Chlorofluoromethane (HCFC-22): ACGIH Threshold Limit Value (TLV) is 1000 ppm TWA-8
hours.
Methylene bisphenyl isocyanate (MDI): ACGIH TLV is 0.005 ppm TWA and OSHA PEL is 0.02
ppm Ceiling. PELs are in accord with those recommended by OSHA, as in the 1989
revision of PELs.

10) STABILITY AND REACTIVITY
CHEMICAL STABILITY
Stable under recommended storage conditions.
INCOMPATIBILITY WITH OTHER MATERIALS
Avoid contact with acids, water, alcohols, amines, ammonia, bases, moist air, and
strong oxidizers. Avoid contact with metals such as aluminum, brass, copper, galvanized
metals, tin, zinc. Avoid contact with moist organic absorbents. Reaction with water
will generate carbon dioxide and heat. Generation of gas can cause pressure buildup in
closed systems. Avoid unintended contact with polyols. The reaction of polyols and
isocyanates generate heat. Diisocyanates react with many materials and the rate of
reaction increases with temperature as well as increased contact; these reactions can
become violent. Contact is increased by stirring or if the other material mixes with
the diisocyanate. Diisocyanates are not soluble in water and are denser than water
and sink to the bottom, but react slowly at the interface. The reaction forms carbon
dioxide gas and a layer of solid polyurea.
HAZARDOUS DECOMPOSITION PRODUCTS
Hazardous decomposition products depend upon temperature, air supply and the presence
of other materials. Gases are released during decomposition.
HAZARDOUS POLYMERIZATION
Can occur. Polymerization can be catalyzed by: strong bases and water. Can react with
itself at temperatures above 320F (160C).

11) TOXICOLOGICAL INFORMATION

in-vitro (test tube) studies;
other in-vitro studies were negative. A mutagenicity study in animals was negative.

12) ECOLOGICAL INFORMATION
MOVEMENT & PARTITIONING
Based on information for MDI and polymeric MDI. In the aquatic or terrestrial
environment, movement is expected to be limited by its reactivity with water forming
predominantly insoluble polyureas.
Volatilization from water to air is expected for HCFC-22, chlorodifluoromethane.
DEGRADATION & PERSISTENCE
Based on information for MDI and polymeric MDI. In the aquatic and terrestrial
environment, material reacts with water forming predominantly insoluble polyureas which
appear to be stable. In the atmospheric environment, material is expected to have a
short tropospheric half-life, based on calculations and by analogy with related
diisocyanates.
ECOTOXICITY
Based on information for MDI and polymerc MDI. The measured ecotoxicity is that of the
hydrolzed product, generally under conditions maximizing production of soluble species.
Material is practically non-toxic to aquatic organisms on an acute basis (LC50/EC50 >
100 mg/L in most sensitive species). The LC50 in earthworm Eisenia foetida is > 1000
mg/kg.
