SRD 50


  • Exceptionally tough, abrasion resistant, high impact material
  • Safe-contains no TDI, MDI, MDA, OR MOCA
  • Easy to handle
  • Room temperature mixing and curing


SRD 50 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. SRD 50 is relatively insenstive to typical environmental moisture
and will make good void-free parts. Because of this product’s exceptional toughness and abrasion resistance, casting made with TC-8750
A/B are particularly suitable for mining and mineral process industries.
