BC 8690E is a two-component urethane elastomer compound specifically designed for casting applications. This product is safe, easy-to-handle, room temperature mixing and curing system that contains no TDI, MDA or MOCA. BC 8690E is insensitive to moisture during storage and normal handling; hence, this system will make dependably good void-free parts without the foaming problems that some conventional urethane systems exhibit. The low shrinkage, low viscosity, superior toughness, and excellent detail reproduction of BC 8690E makes this system ideal for general purpose castings and quality tooling operations.
