Plasite 4100 is a high performance lining-grade coating reinforced with inert flake pigments combined with a special curing system to provide outstanding chemical resistance and physical properties. It has exceptional resistance to inorganic and organic acids, oxidizing agents and salts. It can handle dry heat up to 380 °F (193 °C) and will resist condensing acid vapors (sulfuric) typically found in FGD (flue gas desulfurization) systems.
