BJB Polyurethane TC-8745 A/B

About
TC-8745 A/B is a two-component urethane casting compound that is specifically formulated for high abrasion and impact resistance. It is recommended for the casting of highly wear-resistant production parts and linings. This product is a safe, easy-to-handle, room temperature mixing and curing system that does not contain mercury, MDI, MDA, or MOCA. TC-8745 A/B is relatively insensitive to typical environmental moisture and will make good void-free parts without the problems that some conventional urethane systems exhibit. Because of this product’s exceptional toughness and abrasion resistance, castings made with TC-8745 A/B are particularly suitable for mining and mineral process industries. Product Highlights: Exceptional abrasion and impact resistant Contains no mercury, MDI, MDA or MOCA Easy to handle Room temperature mixing and curing&&
