Material Notes:

BC8990 is a two-component urethane elastomer compound specifically designed for general purpose molding and casting of various shapes. This product is a safe, easy-to-handle, room temperature mixing and curing system that contains no TDI, MDA or MOCA. BC8990 may be used to provide abrasion resistant liners, pads and bumpers. The low shrinkage, low viscosity, superior toughness, and excellent detail reproduction of makes this system ideal for general purpose castings and quality tooling operations. It may also be used in potting and encapsulating applications.Information provided by BCC Products, Inc.
