TECHNOMELT PUR 4520 DR-S 193KG

If not breathing, give artificial respiration. If breathing is difficult, oxygen should be administered by qualified personnel. Move to fresh air. If symptoms persist, seek medical advice.

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

Cool skin rapidly with cold water after contact with molten material. Cover affected areas with clean sheeting or gauze and seek immediate medical attention. No attempt should be made to remove material from skin or to remove contaminated clothing as damaged skin can be easily torn.

Symptoms: Molten adhesive may cause severe burns.

If eye contact occurs with molten material immediately cool with water. Do not remove adhesive. Seek medical attention.

Seek immediate medical attention. Do not induce vomiting. Never give anything by mouth to an unconscious person.

Water spray (fog), foam, dry chemical or carbon dioxide. Use extinguishing measures appropriate to local circumstances and the surrounding environment.

Sealed containers at elevated temperatures or contaminated with water may rupture explosively. During a fire, MDI vapors and other irritating, highly toxic gases may be generated by thermal decomposition or combustion.

Keep unnecessary personnel away. In case of fire, keep containers cool with water spray.

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

Do not allow product to enter sewer or waterways.

Ensure adequate ventilation. If product is spilled in the solid state, pick up and place in an appropriate waste disposal container. If product is spilled in the molten state, allow product to solidify before scraping up and disposing of in an appropriate waste disposal container.

Always be careful around molten material. Avoid skin contact with molten resins. See Section 8 of the SDS for Personal Protective Equipment. Precaution - this product should only be heated to recommended temperatures. Hazards of pyrolysis products emitted are unknown and may be hazardous to health. If recommended temperature is exceeded, there is an increased possibility that MDI may be released. Use caution if using container unloading equipment that inverts product, in order to avoid dislodging product prematurely. Do not place wet or damp solid into melt tank.

Do not let moisture contaminate this material. Product reacts with water to release carbon dioxide, which could build up pressure in closed containers and lead to bursting. Do not reseal if moisture contamination is suspected. Store in original container until ready to use.

Stable under normal conditions of storage and use.

MDI reacts slowly with water to form carbon dioxide gas.

Exothermic. Polymerization may occur at elevated temperature or in the presence of incompatible materials.

Avoid moisture. Container can be pressurised by carbon dioxide due to reaction with humid air and/or water. Extremes of temperature and direct sunlight. Contamination with water.

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

Upon decomposition, this product may yield gaseous nitrogen oxides, carbon monoxide, carbon dioxide and/or low molecular weight hydrocarbons. Hydrogen cyanide. Isocyanate vapors
