MC-145 A/B is a two-component urethane casting compound that can be used with meter-mix-dispense equipment. This product is a safe, easy-to-handle, room temperature mixing and curing system that does not contain TDI, MDI, MDA, or MOCA. MC-145 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 MC-145 A/B are particularly suitable for the mineral process and metal forming industries. Product Uses:
