PENNCOAT 340 Lining is a 45 – 50 mil WFT (Wet Film Thickness) lining system based on premium grade novolac vinyl ester resin polymer chemistry. It utilizes a peroxide based curative for maximum chemical resistance, as well as flake fillers for reduced permeation. It is specifically formulated to be applied by spray in two coats of 22 – 25 mils WFT per coat for a total lining thickness of 36 – 40 mils DFT (Dry Film Thickness).
