Wear Resistance Products
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.
