| TC-9445 A/B is a two-component urethane casting compound that is specifically formulated for high abrasion and impact resistance. It is recommended for use in the casting of highly wear-resistant parts and linings. This product is a safe, easy-to-handle, room temperature mixing and curing system that does not contain TDI, MDI, MDA, or MOCA. TC-9445 A/B is relatively insensitive to typical environmental moisture and will make good void-free parts. Because of this product’s exceptional toughness and abrasion resistance, castings made with TC-9445 A/B are particularly suitable for mining and mineral process industries. Product Highlights: High impact resistance Low viscosity Exceptionally tough, abrasion resistant Easy to handle Room temperature mixing and curing RoHS Compliant&& |
