CAS# 61788-32-7/26140-60-3.
...Inhalation of MDI vapor can irritate the linings of the upper respira-
tory tract causing runny nose, sore throat, coughing and respiratory
sensitization. For further information, see MSDS Section 3.
...Skin contact may cause irritation resulting in reddening, swelling,
rash scaling or blistering. Contact may cause skin sensitization in
some persons resulting in dermatitis (inflammation).
...Absorption through skin, which is accelerated by cleaning skin with
solvents, can lead to symptoms similar to those caused by inhalation.
...Prolonged or repeated skin contact with the unprocessed naphthenic
oils contained in this product may, without washing, cause an increased
risk of skin cancer, liver damage, blood effects and effects on the
unborn based on tests with laboratory animals. Skin cleansing studies
with aromatic oils show that the toxic effects are not likely to occur
in humans if good personal hygiene practices are used.
...Liquid and vapor are irritating to the eyes and can cause tearing,
reddening and swelling.
May be harmful if swallowed.
...Mixing Part A and B components results in a chemical reaction which
can result in an explosive release of pressure in unvented containers.

Potential Health Effects
Routes of Exposure:
Inhalation:
Inhalation of MDI vapors or mists above the recommended exposure
limits (See Section 2) can irritate the linings of the upper respir-
tory tract causing runny nose, sore throat, coughing, chest dis-
comfort, breathlessness and reduced lung function. Exposure to higher
levels may result in bronchitis, pulmonary edema (excessive fluid in
the lung) which may be delayed 4 to 8 hours, and a permanent reduction
of lung function. As a result of previous repeated overexposure or
single large dose, certain individuals develop isocyanate sensitiza-
tion which will cause reaction to future exposures (even at very low
levels) or upon exposure to dust, cold air or other irritants re-
sulting in severe allergic or asthma-like reactions of the lungs.
Employees with a medical history of respiratory conditions should be
informed that exposure to MDI may create an increased health risk.
Employees should be advised of possible delayed effects, such as
coughing or breathing difficulty during the night.

SECTION 3 - HAZARDS IDENTIFICATION (Cont'd)
Skin and Eye:
May react with SKIN protein and moisture causing irritation with the
following symptoms: reddening, swelling, rash, scaling or blistering.
Cured material is difficult to remove. Contact may cause skin sensi-
tization in some persons resulting in dermatitis (inflammation). Per-
sons who develop skin sensitization can exhibit these symptoms upon
contact with very small amounts of liquid or as a result of exposure
to vapor.
Isocyanates absorbed through the skin can also lead to symptoms simi-
lar to those caused by inhalation. Cleaning the skin with solvents
significantly increases this potential. Therefore, skin contact
should be prevented and solvents should never be used to clean product
from skin.
Prolonged or repeated contact with the unprocessed naphthenic oils in
this product may produce serious toxic effects including skin cancer.
Animal tests indicate that prolonged and repeated skin contact to the
oils in this product may produce local skin tumors.
Liquid and vapor are irritating to the EYES and can cause tearing,
reddening and swelling. If left untreated, corneal damage can occur.
The damage is reversible and does not result in permanent injury.
Ingestion:
Oral toxicity is low and, therefore, not expected to be harmful if
swallowed in small amounts. If swallowed, may cause irritation to
the linings of the mouth and gastrointestinal tract. Symptoms may
include sore throat, abdominal pain, nausea, vomiting and diarrhea.
Wash hands completely before eating.
Carcinogenicity Information :
At this time MDI is not listed as a carcinogen. However, the Inter-
national Isocyanate Institute completed and released preliminary re-
sults of a two year inhalation study on rats using aerosols of MDI.
These preliminary results showed that at the highest concentration
(6.0 mg/m 3) there was a significant increase in benign tumors of
the lung in male rats.
This product contains 15-35% of an unprocessed naphthenic oil which
has been shown to cause skin cancer in laboratory animals. It is
classified by IARC as a positive human carcinogen.

SECTION 4 - FIRST AID MEASURES
EYE: In case of eye contact, immediately flush eyes with
large amounts of clean, lukewarm water while holding
eyelids apart. See a physician.
SKIN: In case of skin contact, immediately remove any contam-
inated clothing. Promptly cleanse the area with water-
less hand cleaner, thoroughly clean fingernails and
follow by washing with soap and water. NEVER USE
SOLVENTS TO CLEAN SKIN! If irritation develops or
persists, consult a physician.
INHALATION: If irritation due to inhalation develops, get fresh air.
Immediate or delayed symptoms requiring oxygen or arti-
ficial respiration may develop. If this occurs, get
immediate medical attention.
INGESTION: If swallowed, contact a physician or Poison Control
Center immediately. Do not induce vomiting unless
directed to do so by medical personnel. Never give
anything by mouth to an unconscious person.
SECTION 5 - FIRE FIGHTING MEASURES
Flash Point: 200癈/392癋 (Estimated) Flammable Limits:
Method Used: Cleveland Open Cup LEL N/A UEL N/A
N.F.P.A. Rating: H-2 F-1 R-1
Extinguishing Media
Dry chemical, Carbon dioxide or chemical foam.
Special Fire Fighting Procedures
Firefighters should be equipped with self-contained breathing appara-
tus (SCBA) and full emergency equipment. Irritating, highly toxic
gases may be generated by thermal decomposition or combustion.
People who are fighting isocyanate fires must be protected against
nitrogen oxide fumes and isocyanate vapors by wearing positive
pressure self-contained breathing apparatus and full protective
clothing.
Unusual Fire and Explosion Hazards
At temperatures above 320癋, MDI can polymerize and decompose which
can cause pressure build-up in closed containers. Explosive rupture
is possible. Therefore, use cold water to cool fire exposed
containers.

SECTION 6 - ACCIDENTAL RELEASE MEASURES
U.S. RELEASES
Waste of this product is not defined as hazardous according to U.S.
EPA (40 CFR 261.3). If spilled, observe all safety precautions
noted above. Remove all personnel who are not properly protected from
the area. Absorb spill with an inert, noncombustible material and
remove for disposal. Containers used to remove waste MUST NOT be
sealed for 24 hours. See MSDS Section 10 - Reactivity Data.
CANADIAN RELEASES
Observe precautions noted above. Remove material for disposal.
SECTION 7 - HANDLING AND STORAGE INFORMATION
Precautionary Measures :
... Do not get on skin. Wear impervious gloves and work clothes with
long sleeves whenever skin contact is possible. Wash thoroughly
after handling.
... Never use solvents to clean skin. If skin contact does occur,
promptly cleanse according to first aid instructions.
... Avoid contact with eyes. Wear eye protection whenever contact is
possible.
... Avoid inhalation of vapor. Use with adequate ventilation. If you
can smell MDI (pungent, irritating odor) or if your nose or eyes
are irritated, the allowable exposure limits have been exceeded
and a hazardous condition exists. Respirators must be worn if
airborne exposures can not be maintained below exposure limits -
consult MSDS Sections 2 and 8.
... Keep individual component containers closed when not in use. Do
not seal containers once components are mixed and reaction has begun.
... Keep away from food.
... Do not reuse empty containers.
... FOR PROFESSIONAL USE ONLY. KEEP OUT OF CHILDREN'S REACH.
SECTION 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION/CANADIAN EXPOSURE LIMITS
Ventilation:
Portable ventilation should be used to prevent vapor build-up during
application in enclosed or depressed areas where natural ventilation
may not be adequate. Portable equipment such as a Coppus Vano] por-
table blower/exhauster should be used in accordance with the manufac-
turer's instructions.
Respiratory Protection :
MDI has a very low vapor pressure and is not likely to exceed the
permissible exposure limit (PEL) in unconfined spaces. Therefore,
respiratory protection is not normally required in well ventilated
areas except for individuals who are hypersensitive to isocyanates.
It should also be noted that although chemical cartridge respirators
may provide protection against isocyanate exposure, they are not
approved for such use by NIOSH. This is because MDI has poor warning
properties. (The level at which it can be detected by odor is signi-
ficantly above the PEL.) In confined areas, indoors or where there is
inadequate ventilation, supplied air or self-contained breathing
apparatus may be required.
M-85651 MATERIAL SAFETY DATA SHEET Page 7 of 13
SECTION 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION/CANADIAN EXPOSURE LIMITS (Cont'd)
Skin Protection:
Impervious gloves resistant to Methylene Bisphenyl Isocyanate (MDI)
and naphthenic oils should be worn anytime direct contact is possible.
Eye Protection:
Safety glasses, splash goggles or a full face shield are recommended
to prevent contact due to splashing and exposure to high vapor con-
centrations.
Other Protective Clothing or Equipment :
Work clothes with long sleeves and work boots.
Work/Hygienic Practices :
Use work practices to prevent inhalation of vapor and direct skin
contact. Always use good personal hygiene practices after handling.
This product contains aromatic oils. Aromatic oils contain high
concentrations of polycyclic aromatic compounds, some of which
have been shown to cause skin cancer in humans under conditions
of poor personal hygiene and prolonged, repeated contact. Certain
components of these compounds have also produced harmful effects in
laboratory animals after absorption through the skin. Although
these effects have been principally to the liver and bloodforming
organs, the unborn young of these animals may also be affected.
The animal experiments also showed that these effects can be pre-
vented by thorough removal of the oil from the skin. Skin cleansing
studies with aromatic oils show that the toxic effects are not
likely to occur in humans if good personal hygiene practices are
used.
Handling and Storage Precautions:
Store indoors at 50-95癋 in original, unopened containers. Protect
from atmospheric moisture. Do not use at temperatures above 95癋
as this may create an increased risk of vapor inhalation. Consult
MSDS Section 7 and 8.
