MIXING INSTRUCTIONS:
1. Pre-mix both components in their original containers to insure consistency.
2. Pre-heat both components to 50° - 60°C, to lower viscosity for ease of mixing.
3. Measure out equal parts (by weight) of both components.
4. Mix thoroughly, scraping the sides and bottom of container.
5. Evacuate @29 in. Hg for void-free casting.
6. Pour into unit or cavity.
CURE SCHEDULES:
2 hours @120°C or 24 hours @75°C.

HEALTH CAUTION:
Avoid breathing possible fumes, mists and vapors which can cause severe respiratory damage. Use of NIOSH approved breathing apparatus is required for more than minimal exposure. Always work in areas with adequate ventilation to allow dissipation of polyamine and other chemical fumes, and where applicable, solvent fumes. Use of goggles, protective garments, rubber gloves, protective cream is required. If material gets into eyes, flush thoroughly with clear water for twenty (20) minutes; then seek medical treatment. Avoid skin contact. Material can cause contact dermatitis. Always wash exposed areas immediately, using warm water and soap, followed by rinsing with clean water. Observe all safety precautions. It is important when using solvent based materials or solvents to keep away from open flame or ignition source.
