PRODUCT HIGHLIGHTS:
- Exceptionally tough, abrasion resistant, high impact material
- Safe-contains no TDI, MDI, MDA, OR MOCA
- Easy to handle
- Room temperature mixing and curing
PRODUCT DESCRIPTION:
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.
PRODUCT HIGHLIGHTS:
- Abrasion-resistant parts and lining
- Foundary patterns and core box liners
- Roller facings and casters
- Potting and encapsulation
- Cutting table tops
- Metal forming die facings
- Troughs, chutes and other equipment contacting any abrasive materials
- Machinery base pads and gears
