Specific Gravity 1.36Pot Life @ 25oC, days >14Shelf Life @ -15°C (from date of manufacture), days 365 Flash Point - See SDSTYPICAL CURING PERFORMANCE Cure Schedule5 to 10 minutes @ 80°CWith all curing systems, the time required for cure depends on the rate of heating.
Cure rate depends on the mass of material to be heated and intimate contact with the heat source.
Use suggested cure conditions as general guidelines. Other cure conditions may yield satisfactory results.
The above cure profiles are guideline recommendations. Cure conditions (time and temperature) may vary based on customers’ experience and their application requirements, as well as customer curing equipment, oven loading and actual oven temperatures.
