Wear Resistant Compound (WRC)

Wear Resistant Compound (WRC) is a carbide filled, fast setting, no VOC, high hardness epoxy composite coating designed for localized repair of components operating in highly abrasive environments.

WRC is available in two formulations differing only in working/cure time, enabling applications across a range of temperatures. For example, higher application temperatures require a longer inherent working time. The two formulations are designated as WRC15 and WRC30. Working/cure times of the two formulations are compared within the Physical Properties section.

How It Works

The WRC compound is a field-mixed, ceramic-filled, two-part epoxy supplied in pre-measured quantities. The cured compound exhibits superior mechanical properties with exceptional stability in abrasive environments. The epoxy composite can be used to rebuild, patch, reinforce and return to service damaged chutes, hoppers, conveyors, mixing devices, housings, tanks, and pipes. The filled compound resists abrasion from both large and small particles for a wide range of loads and speeds.

Materials

Supplied in 6 lb (2.72 kg) kits; parts A and B pre-measured and packaged separately. Available in kits including spatula and gloves.
