Technical Details & Test Data

Processing Parameters

Blend T component into R component. Mix for about two minutes. Pour at decrease of viscosity and perception of exothermic heat. When foaming action has ceased, postcure immediately. Average cure is about two hours at 200°F. Cool part to 110-130°F before stripping from mold.

Storage & Handling

Storage

Avoid moisture contamination during storage, handling, and processing. Store the polyol and isocyanate components from 65°F to 85°F. Do not expose isocyanate component to lower temperatures as freezing may occur

Shelf Life

The shelf life is 12 months if stored in original unopened containers
