USE INSTRUCTIONS:
1. Mix Insulcast 782 thoroughly prior to use.
2. Preheating the INSULCAST 782 to 65°C will reduce the viscosity significantly.
3. Pour de-gassed material slowly to avoid air entrapment.
CURE SCHEDULES:
Dipped Units:
6 - 8 hours @95°C - lowest shrinkage
3 - 5 hours @105°C
2-3 hours @120°C plus Post Cure 1-2 hours @105°C-115°C - Lowest shrinkage
Post cure 2 hours @150°C for optimum high temperature properties.
STORAGE REQUIREMENTS:
One component epoxies are pre-catalyzed and have a limited shelf-life. Storage at elevated temperatures will result in a shortened shelf-life and premature gelation. Store material in a cool place.
IMPORTANT:
The following supersedes any provision in your company's forms, letters and papers. AMERICAN SAFETY TECHNOLOGIES, INC. makes NO WARRANTY, WHETHER EXPRESSED OR IMPLIED, INCLUDING WARRANTIES of MERCHANTABILITY OR of FITNESS FOR A PARTICULAR PURPOSE FOR THIS PRODUCT. No statements or recommendations contained in the product literature are to be construed as inducements to infringe any relevant patent, now or thereafter in existence.

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.
