RD 60 

PRODUCT HIGHLIGHTS:

  • Exceptionally tough, abrasion resistant, high impact material.

  • Contains no TDI, MDI, MDA, OR MOCA.

  • Easy to handle.

  • Room temperature mixing and curing.

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

this is text meant just to take up lots of space at the bottom of the page, so that if there is only a table or something in the content part of this page, the content still takes up the majority of the screen. if there is not any text here, then sometimes there will be just a table here, and the left navigation bar to the left will be kinda wide...
