PRODUCT DESCRIPTION:
RD 60 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. RD 60 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 RD 60 are particularly suitable for mining and mineral process industries.
TYPICAL PRODUCT USES:
-
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
