A high-performance, 100% solids, low odor, environmentally safe novolac epoxy coating. Protecto-Coat 105XT uses a moisture-tolerant primer and two coats of graphite flake-filled novolac epoxy resin to protect concrete and metal substrates. The novolac epoxy binder and overlapping flake filler provide the low permeability, high film integrity, and excellent chemical resistance required for prolonged substrate protection.
