3. HAZARDS IDENTIFICATION
Toxicity: Acute inhalation: Inhalation of dicyclohexylmeth-
ane-4,4'-diisocyanate at concentrations above the
TLV can irritate (burning sensation) the mucous
membranes in the respiratory tract (Nose, throat,
lungs) causing runny nose, sore throat, coughing,
chest discomfort, shortness of breath and reduced
lung function (breathing obstruction). Persons
with a preexisting, nonspecific bronchial
hyperreactivity can respond to concentrations
below the TLV with similar symptoms as well as
asthma attack. Exposure well above the TLV may
lead to bronchitis, bronchial spasm and pulmonary
edema (fluid in lungs). These effects are usually

3. HAZARDS IDENTIFICATION (continued)
reversable. Chemical or hypersensitive pneumonitis
with flu-like symptoms (e.g., fever, chills) has
also been reported.
Chronic inhalation: 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.
This increased lung sensitivity can persist for
weeks and in severe cases for several years.
Overexposure to isocyanates has also been reported
to cause lung damage (including decrease in lung
function) which may be permanent. Sensitization
can either be temporary or permanent.
Acute skin contact: Dicyclohexylmethane-4,4'-
diisocyanate is a primary skin irritant. It
reacts with protein and moisture and can cause
irritation. Symptoms of skin irritation include:
redness, swelling, rash, scaling and blistering.
Dicyclohexylmethane-4,4'-diisocyanate is also a
potent sensitizer. Experience indicates that
direct contact is the route of exposure most
likely to cause sensitization. Once sensitized,
an individual may react even to airborne levels
below the TLV with the following symptoms:
itching and tingling or the earlobes and neck,
rash, hives, swelling of the arms and legs or
other symptoms common to allergic dermatitis.
These symptoms may be immediate or delayed.
Chronic skin contact: Prolonged contact can cause
reddening, swelling, rash, scaling, blistering and
in some cases, skin sensitization. Individuals who
have skin sensitization can develop these symptoms
from contact with liquid or vapor. Animal tests
have indicated that respiratory sensitization can
result from skin contact with dicyclohexyl-
methane-4,4'-diisocyanate.

digestive tract. Symptoms can include sore throat,
abdominal pain, nausea, vomiting and diarrhea.
Primary Routes of Entry: Skin contact, inhalation of vapors and mist,
eye contact.
Signs and Symptoms
of Exposure: Eye, skin, and respiratory irritation. Allergic
skin or respiratory reaction.

4. FIRST AID MEASURES
Ingestion: Do not induce vomiting. Give one to two cups of
milk or water to drink. Do not give anything by
mouth to an unconscious person. Consult a
physician.
Inhalation: Move to an area free from risk of further exposure
Administer oxygen or artificial respiration as
needed. Obtain medical attention. Asthmatic-type
symptoms may develop and may be immediate or
delayed up to several hours. Consult a physician.
Skin Contact: Remove contaminated clothing. Wash affected skin
thoroughly with soap and water. Wash contaminated
clothing thoroughly before reuse. For severe
exposures, get under safety shower after removing

clothing, then get medical attention. For lesser
exposures, seek medical attention if irritation
develops or persists after area is washed.
Eye Contact: Flush with copious amount of water, preferably,
lukewarm water for at least 15 minutes, holding
eyelids open all the time. Refer individual to a
physician or ophthalmologist for immediate
follow-up.
5. FIRE FIGHTING MEASURES
Flash Point: More than 200掳F Method: ASTM D3278-89
Recommended
Extinguishing Agents: Carbon dioxide, foam, dry chemical.
Special Firefighting
Procedures: Full emergency equipment with self-contained
breathing apparatus and full protective clothing
should be worn by firefighters. During a fire,
vapors and other irritating, highly toxic gases
may be generated by thermal decomposition or
combustion.
Hazardous Products formed
by Fire or Thermal Decomp Carbon monoxide, oxides of nitrogen, traces of
hydrogen cyanide, MDI vapors or aerosols.
Unusual Fire or
Explosion Hazards: Closed containers may explode when exposed to
extreme heat or burst when contaminated with
water.
Explosive Limits:

(% by volume in air)Upper Not available
6. ACCIDENTAL RELEASE MEASURES
Steps to be taken in case
of spill or leak: Evacuate nonessential personnel. Remove all
sources of ignition and ventilate the area. Dike
or impound spilled material and control further
spillage if necessary. Cover the spill with
sawdust or other absorbent, shovel into suitable
unsealed containers, transport to well-ventilated
area (outside) and treat with neutralizing
solution: mixture of water (80%) with non-ionic
surfactant Tergitol TMN-10 (20%), or water (90%),
concentrated ammonia (3-8%), and detergent (2%).
Add about ten parts of neutralizer per part of
isocyanate, with mixing. Allow to stand uncovered

for 48 hours to let carbon dioxide escape.
Clean-up: Decontaminate floor with decontamination
solution letting stand for at least 15 minutes.
7. HANDLING AND STORAGE
Safe Storage: Store between 77掳F and 122掳F. Store in tightly
closed containers to prevent moisture
contamination. Do not reseal if contamination is
suspected. At maximun storage temperatures noted,
material may slowly polymerize without hazard.
ideal storage range is 86掳F-104掳F. Avoid contact
with eyes and skin.
Special Sensitivity: If container is exposed to
temperatures above 122掳F, such as a fire
situation, it can be pressurized and possibly
rupture violently. Dicyclohexylmethane-4,4'-
diisocyanate reacts slowly with water to form
carbon dioxide gas. Production of this gas can
cause sealed containers to expand and possible
rupture explosively.
(Contact Loctite Customer Service 1-800-243-4874 for shelf life information)
Handling: Avoid contact with skin and eyes. Do not breathe
vapor or mists.
8. EXPOSURE CONTROLS, PERSONAL PROTECTION
Eyes: Safety glasses, splash goggles or face shield.
Contact lenses should not be worn.
Skin: Any area of skin that could potentially come in
contact with this material, must be covered by a
permeation resistant barrier (i.e. rubber gloves,
neoprene apron, chemical suit, etc.) When there is
a potential for splash, a full chemical suit is
required. When the application results in vapor
or mist, a full permeation resistant suit
including head covering, and face shield, gloves,
and overshoes is required.
Ventilation: Local exhaust should be used to maintain levels
below the TLV when material is processed, heated
or spray applied. Standard reference sources
regarding industrial ventilation (i.e., ACGIH
Industrial Ventilation) should be consulted for
guidance about adequate ventilation
Monotoring: Isocyanate exposure levels must be monitored. Monitoring
of airborne isocyanates in the breathing zone of individuals should
become part of the overall employee exposure characterization program.

8. EXPOSURE CONTROLS, PERSONAL PROTECTION (continued)
Monitoring techniques have been developed by NIOSH and OSHA. Upon
request the manufacturer can make available methods which are
modifications of these NIOSH and OSHA methods.
Medical Surveillance: Medical supervision of all employees who handle
or come in contact with isocyanates is recommended. These should
include preemployment and periodic medical examinations with
pulmonary function tests (FEV, FVC as a minimum). Persons with
asthmatic-type conditions, chronic bronchitis, or other chronic
respiratory diseases or recurrent skin eczema or sensitization should
be excluded from working with isocyanates. Once a person is diagnosed
as sensitized to an isocyanate, no further exposure can be permitted.
Respiratory In some situations, a respirator may be necessary
in addition to ventilation. The use of a positive
pressure air-supplied respirator is mandatory
when: airborne concentration of isocyanate are
known to exceed 0.005 ppm; operations are
performed in a confined space or area with
limited ventilation; material is heated or
sprayed. An air-purifying respirator is not
generally recommended based on the poor warning
properties of the isocyanate.
See Section 2 for Exposure Limits.
