| About |
|---|
| BC8160 is a low viscosity two-component urethane casting compound that is specifically formulated for its flexural and impact strength. It is recommended for use for the production casting of highly wear-resistant parts and prototypes. BC8160 can be used to develop thermoplastics type prototypes. This product is a safe, easy-to-handle, room temperature mixing and curing system that does not contain TDI, MDI, or MOCA. BC8160 is relatively insensitive to typical environmental moisture and will make good void-free parts without the problems that some conventional urethane systems exhibit.&& |
