LOCTITE UR S119

Move to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

Symptoms: Asthmatic-type symptoms may develop and may be immediate or delayed up to several hours.

Immediately flush skin with plenty of water (using soap, if available). Remove contaminated clothing and footwear. For severe exposures, get under safety shower after removing clothing. Wash clothing before reuse.

Symptoms: This compound is a known skin sensitizer.

Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.

Symptoms: Workplace vapors have produced reversible corneal epithelial edema impairing vision.

Do not induce vomiting. Never give anything by mouth to an unconscious person.

Foam, dry chemical or carbon dioxide.

Not available.

During a fire, MDI vapors and other irritating, highly toxic gases may be generated by thermal decomposition or combustion. At temperatures above 204.4°C (400°F), polymeric MDI can polymerize and decompose which can cause pressure build-up in closed containers. Explosive rupture is possible. Sealed containers at elevated temperatures or contaminated with water may rupture explosively.

Wear self-contained breathing apparatus and full protective clothing, such as turn-out gear.

Use personal protection recommended in Section 8, isolate the hazard area and deny entry to unnecessary and unprotected personnel.

For minor spills, absorb isocyanates with sawdust or other absorbent, shovel into suitable unsealed containers, transport to well ventilated area (outside) and treat with neutralizing solution: mixture of 80% water and 20% non-ionic surfactant Tergitol TMN-10; or 90% water, 3-8% concentrated ammonia and 2% detergent. Add about ten parts of neutralizer per part of isocyanate, with mixing. Allow to stand uncovered for 48 hours to let carbon dioxide escape.

Large quantities may be pumped into closed, but not sealed containers for disposal.

Do not allow product to enter sewer or waterways.

Remove all sources of ignition. Evacuate and ventilate spill area; dike spill to prevent entry into water system; wear full protective equipment during clean-up.

Materials: sawdust or other absorbent

Prevent contact with eyes, skin and clothing. Do not breathe vapor and mist. Wash thoroughly after handling. Exposure to vapors of heated MDI can be extremely dangerous. Use only with adequate ventilation. Protect from moisture. Keep container closed. Employee education and training in the safe use and handling of this compound are required under the OSHA Hazard Communication Standard.

Keep container tightly closed and in a cool, well-ventilated place away from incompatible materials. Store away from heat, sparks, flames, or other sources of ignition. Do not let moisture contaminate this material. Protect from direct sunlight.

Wash thoroughly after handling.

Store away from heat, sparks, flames, or other sources of ignition.

Stable under normal conditions of storage and use.

Not available.

Contact with moisture, other materials that react with isocyanates, or temperatures above 350° F (177° C), may cause polymerization. Uncontrolled polymerization may cause rapid evolution of heat and increase in pressure that could result in violent rupture of sealed storage vessels or containers.

Keep away from heat, ignition sources and incompatible materials. Contamination with water. Avoid moisture. Extremes of temperature and direct sunlight. Prolonged heating at temperatures above 150 °C. Container can be pressurised by carbon dioxide due to reaction with humid air and/or water.

Water. Alcohols. Amines. Ammonia. Strong acids and strong bases.

Irritating organic vapours. Oxides of carbon. Oxides of nitrogen. Hydrogen cyanide. MDI vapors and aerosols. Isocyanates.
