TECHNOMELT PUR 34-712 A764 known as PUR-FECT LOK (TM) 170-7734B 34

Move to fresh air in case of accidental inhalation of dust or fumes from overheating or combustion. Get medical attention. If not breathing, give artificial respiration.

Cool melted product on skin with plenty of water. Do not remove solidified product. 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.

If material is ingested, immediately contact a physician or poison control center.

Use extinguishing measures appropriate to local circumstances and the surrounding environment. Dry chemical. Carbon dioxide.

Sealed containers at elevated temperatures or contaminated with water may rupture explosively.

In case of fire, keep containers cool with water spray.

Isolate the hazard area and deny entry to unnecessary and unprotected personnel.

Do not allow material to contaminate ground water system. Prevent further leakage or spillage if safe to do so.

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.

Wear suitable protective clothing, safety glasses and gloves. Always be careful around molten material. Avoid skin contact with molten resins. 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. Follow suggested application temperature. 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.

Empty drums should be completely drained, properly bunged and promptly returned to a drum reconditioner, or promptly disposed of. Keep containers closed when not in use. 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.

Stable

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.

Humid air and/or water will produce carbon dioxide which will pressurize the container. Reaction with water, formation of CO2 Alcohols. Amines. Ammonia.

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