Loctite PC 7117 is a 2-part, ceramic-filled, brushable epoxy-based surface coating designed to protect parts from fine particle abrasion or erosion on metals (with or without chemical attack). It is designed for parts such as impellers, butterfly valves, pump housings, cyclones and lining tanks. It offers long working life with surfaces dry in 3.5 hours to leave a high gloss, low friction coating.
