Master Bond Polymer System EP21ARHT is a two component epoxy resin compound for durable, high performance, high strength coatings, liners and adhesive/sealants with outstanding acid and overall chemical resistance. The EP21ARHT compound is formulated to cure at room temperature or more rapidly at elevated temperatures, with a convenient two-to-one non-critical mix ratio by weight and offers a degree of acid resistance unmatched by any other currently available room temperature or heat curing resin composition. It can successfully withstand, for example, prolonged immersion in even 96-98% sulfuric acid and 20% hydrochloric acid for more than a year. A primary application for its use would be a coating and/or liner for chemical storage tanks, fuel storage tanks, chemical piping, scrubbers, chemical processing equipment, etc. Master Bond Polymer System EP21ARHT also features excellent resistance to fuels, oils, ethanol and many active organic solvents. In addition, it has superb bonding strength and is an excellent adhesive especially in acid environments.
