TECHNOMELT PUR 3317 BR 12KG

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.

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

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.

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.

Local exhaust ventilation is recommended when general ventilation is not sufficient to control airborne contamination. Local exhaust should be used to maintain levels below the TLV whenever MDI 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. Air monitoring: Monitoring of airborne isocyanates in the breathing zone of individuals should become part of the overall employee exposure characterization program. Medical Surveillance: Medical supervision of all employees who handle or come in contact with isocyanates is recommended. Persons with asthmatic-type conditions, chronic bronchitis, 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.

Safety goggles or safety glasses with side shields. Full face protection should be used if the potential for splashing or spraying of product exists. Do not wear contact lenses.

Concentrations greater than the TLV can occur when MDI is sprayed, heated or used in a poorly ventilated area. Use NIOSH approved respirator if there is potential to exceed exposure limit(s). A positive pressure, supplied-air respirator or a self-contained breathing apparatus is recommended when: airborne concentrations 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. Do not inhale vapors and fumes. Observe OSHA regulations for respirator use (29 CFR 1910.134).

Insulated gloves and long sleeved clothing are strongly recommended when working with molten adhesive.

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
