Chesterton ARC 982 100% Novolac acid resistant coating (discontinued **)
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Description: An advanced polymer composite formulated to protect equipment from extreme chemical attack and corrosion. A low viscosity composite that is applied by brush, squeegee, or a plural component sprayer system. ARC 982 may be applied at a minimum thickness of 250 microns (10 mils) per coat. A two-coat application of ARC 982 provides protection from concentrated acids, alkailes, and solvents. The cured composite provides outstanding chemical resistance with a high gloss finish. Benefits: Excellent resistance to a wide variety of concentrated acids such as sulfuric acid up to 98% and fluctuating chemical environments. ARC 982 outlasts rubber and other traditional lining materials as it is resistant to aging and embrittlement Tough resin structure resists thermal-mechanical shock Outstanding adhesion results in reliable performance with no under film corrosion Holiday testable per NACE RP0188 Suggested Uses: Chemical Storage Tanks Exhaust Gas Ductwork Impellers Pump Casings Structural Steel Valves Chimneys and Stacks Fans and Housings Heat Exchangers Tanks and Piping Reaction Vessels Information provided by Chesterton
