VENTILATION: Control airborne concentration below the exposure guideline. Use only with

adequate ventilation. Local exhaust ventilation may be necessary for some operations.

RESPIRATORY PROTECTION: Atmospheric levels should be maintained below the exposure

guideline. When respiratory protection is required for certain operations (e.g. spraying ), use an approved

positive pressure air supplied respirator. In confined spaces or areas with poor ventilation this is

mandatory.

SKIN PROTECTION: Use protective clothing impervious to this material. Butyl/Nitrile/neoprene gloves

should be worn. Safety shower should be located in work area. Remove contaminated clothing

immediately, wash skin area with soap and water, and launder clothing before reuse. Contaminated

leather such as shoes, belts and watchbands, should be removed and thoroughly washed before reuse. .

EYE PROTECTION: Use chemical goggles or safety glasses with side shields. If vapor exposure causes

eye irritation, use a full face air fed respirator. Eye wash fountain and emergency showers should be

located in immediate work area.

10. REACTIVITY AND STABILITY

Hazardous polymerization is very unlikely to occur. Materials such as oxidizing agents and isocyanates

and polyurethanes should be avoided as these will cause exothermic polymerization. Avoid extreme heat.

Fire, pyrolysis and thermal decomposition will produce noxious gases such as CO, CO

, NOx, amines,

ammonia and others. The material is designed as an accelerator curing agent for epoxy resins and will

react with them to give a hard glassy polymer with the evolution of heat.
