Epoxy system resists aggressive chemicals

Developed for coating and lining storage tanks, piping, scrubbers, and processing equipment in the chemical industry, Master Bond EP21ARHT features good chemical, fuel, and acid resistance.

Also widely used in electronic, electrical, and metalworking industries, it can even successfully withstand immersion to 96-98% sulphuric acid and 20% hydrochloric acid for more than a year.

This two component epoxy cures at room temperature with minimal shrinkage, or more rapidly at elevated temperatures. Once fully cured, it produces a bond strength greater than 2,200 psi. The material can be thermally cycled over wide temperature range and features superior electrical insulation capabilities and a low coefficient of thermal expansion. EP21ARHT bonds well to metals, ceramics, glass and many plastics.

This epoxy offers a convenient non-critical 2 to 1 mix ratio by weight. It is colour coded, with part A being clear and part B amber. Master Bond Polymer System EP21ARHT is available for purchase in pint, quart, gallon, and 5 gallon container kits.
