Inhalation:
Respiratory system; Skin; Eyes;
At room temperature, MDI vapors are minimal due to low vapor pressure. May cause respiratory
sensitization with asthma-like symptoms in susceptable individuals. Impaired lung function has
been associated with overesposure to isocyanates. MDI concentrations below the exposure

Skin Contact:
Eye Contact:
spraying, foaming or otherwise mechanically dispersing operations way generate vapor or aerosol
concentrations sufficient to cause irritation or other adverse effects.
Prolonged or repeated exposure can cause skin irritation, reddening, dermatitis and in some cases
sensitization. Skin contact may result in allergic reactions or respiratory sensitization, but it is not
expected to result in absorption of amounts sufficient to cause other adverse effects. May stain
skin.
As a liquid or dust, may cause irritation, inflammation, and/or damage to sensitive eye tissue.
Symptoms include watering or discomfort of the eyes. Corneal injury is unlikely. As a liquid or dust,
may cause irritation, inflammation, and/or damage to sensitive eye tissue. Symptoms include
watering or discomfort of the eyes. Corneal injury is unlikely.
Ingestion: Single dose oral exposure is low. Can result in irritation and corrosive action in the mouth, throat
and digestive tract.

4 FIRST AID MEASURES
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 immediately. Get
immediate medical attention.
Skin Contact:Wash off in flowing warm water or shower with soap. Remove and wash contaminated clothing. Properly
dispose of any articles that cannot be decontaminated, like leather belts. If redness, burning or itching
develops or persists after the area has been washed, consult a physician.
Eye Contact: Flush with large amounts of water for 15 minutes. Materials containing MDI may react with the moisture in
the eye forming a thick material that is difficult to remove. Get immediate medical attention.
Ingestion: Do not induce vomiting or give liquids unless directed to do so by medical personnel. Never give anything
by mouth to an unconscious person. Seek medical attention.
5 FIRE FIGHTING MEASURES
Flammability: OSHA – none; DOT – none
Flash Point: >250 F
Burning Rate: N/A
Flash Point Method: COC
Autoignition Temp: N/A
LEL: N/A
UEL: N/A
Use dry chemical, foam, carbon dioxide, or halogenated agents. If water is used, use very large quantities. The reaction
between water and hot isocyanate may be vigorous. If possible, contain fire run-off water.
Protective Equipment: Wear positive-pressure self-contained breathing apparatus with full face mask and full protective
clothing.
Unusual Hazards: At temperatures greater than 400 F, polymeric MDI can polymerize and decompose which will cause
pressure build-up in closed containers. Explosive rupture is possible. Water contamination will produce carbon dioxide. Do not
reseal contaminated containers as pressure buildup may rupture the containers. Downwind personnel must be evacuated.
Fire Degradation Products: Isocyanate vapor and mist, carbon dioxide, carbon monoxide, nitrogen oxides and traces of
hydrogen cyanide.
Revision Date: 2/27/2019SDS Number: ED77.9-A-30000-S75 CA Page:2 / 8
6 ACCIDENTAL RELEASE MEASURES
Spill: Evacuate spill area. With adequate ventilation and appropriate personal protective equipment, cover the area with an
inert absorbent material such as clay or vermiculite and transfer to metal waste containers. Move container to a well ventilated
area (outside), but do not seal the container with the isocyanate mixture. Larger quantities of liquid may be transferred directly
to drums for disposal. Decontaminate or discard all clean-up equipment.
NOTE: ISOCYANATES WILL REACT WITH WATER AND GENERATE CARBON DIOXIDE. THIS COULD RESULT IN THE
RUPTURE OF ANY CLOSED CONTAINERS.
Clean up: The area should then be flushed with a decontamination solution. The decontamination solution is a 5-10% mixture
of sodium carbonate and 0.5% liquid detergent in water solution or a 3-8% concentrated ammonium hydroxide and 0.5%
liquid detergent in water. Use 10 parts decontamination solution to 1 part spilled material.
If the ammonium hydroxide solution is used, ammonia will be evolved as a vapor. Use caution to avoid exposure to high
concentrations of ammonia. Allow spill clean up to vent for 48 hours letting evolved carbon dioxide to escape.
7 HANDLING AND STORAGE
Handling Precautions: Handling: Use personal protective equipment when transferring material to or from drums,
totes or other containers. The reaction of polyols and isocyanates generates heat. Contact of
the reacting materials with skin or eyes can cause irritiation and may be difficult to remove
from the affected areas. Immediately wash affected areas with plenty of water and seek
medical attention. In addition, such contact increases the risk of exposure to isocyanate
vapors. Do not smoke or use naked lights, open flames, space heaters, or other ignition
sources near pouring, frothing or spraying operations.
Special Emphasis for Spray Applications: Inspect the application area from the potential to
expose other persons or for overspray to drift onto buildings, vehicles or other property. When
spraying building exteriors, persons entering or exiting the building as well as those inside
could be exposed to polyisocyanates due to wind conditions, open windows or air intakes. Do
not begin application work until these potential problems have been corrected.
Storage Requirements: When stored between 60 -85 F in sealed containers, typical shelf life is 6 months or more
from the date of manufacture. Consult technical data sheet for shelf life requirements affecting
performance quality. Should freezing occur, the material must be thawed completely and
mixed until uniform. Opened containers must be handled properly to prevent moisture pickup.
8 EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls: MDI has a low vapor pressure at room temperature. General/local ventilation typically control
vapor levels very adequately. Uses requiring heating and/or spraying may require more
agressive engineering controls or PPE. Monitoring is required to determine engineering
controls.
Personal Protective
Equipment:
HMIS PP, X | Consult your supervisor for special instructions
Respiratory protection: Where risk assessment shows air-purifying respirators are appropriate
use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as
a backup to engineering controls. If the respirator is the sole means of protection, use a full-
face supplied air respirator. Use respirators and components tested and approved under
appropriate government standards such as NIOSH (US) or CEN (EU).
Hand protection: Handle with gloves. Gloves must be inspected prior to use. Use proper glove
removal technique (without touching gloves outer surface) to avoid skin contact with this
product. Dispose of contaminated gloves after use in accordance with applicable laws and
good laboratory practices. Wash and dry hands.
Eye protection: Face shield and safety glasses Use equipment for eye protection tested and
approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin and body protection: Complete suit protecting against chemicals, The type of protective
equipment must be selected according to the concentration and amount of the dangerous
substance at the specific workplace.
Hygiene measures: Avoid contact with skin, eyes and clothing. Wash hands before breaks and
immediately after handling the product.
