Chemically resistant epoxy withstands year in acid
For applications demanding chemical resistance—acids, fuels, and oils—Master Bond has
developed EP21AR, a two-component epoxy that can withstand harsh, acidic environments. The
epoxy can withstand prolonged immersion in 96 to 98% sulfuric acid and 36% hydrochloric acid
for over a year.
With a dielectric strength of 400 volts/mil, EP21AR is a durable and stable epoxy that is
also an electrical insulator. Its coefficient of thermal expansion is 45-55 ppm/°C, and it
is serviceable from -60°F to +275°F. It produces high-strength, abrasion-resistant bonds
with a tensile strength over 10,000 psi, a shear strength exceeding 2,700 psi, and a
compressive strength greater than 14,000 psi at 75°F.
EP21AR is easy to use with a 2 to 1 mix ratio by weight, and a mixed viscosity of 10,000-
15,000 cps. The epoxy isn't reactive with solvents or diluents and can be applied smoothly in
any thickness. This epoxy has a working life of 45 to 55 minutes at ambient temperature for a
200 gram batch, and cures at room temperature. It bonds well to a variety of substrates,
including metals, glass, ceramics, cements, vulcanized rubbers, wood, and plastics.
EP21AR is packaged in pint, quart, gallon, and five gallon container kits. It is used in
industries including: oil and chemical processing, maintenance and repair, optics,
metalworking, appliance, and electrical/electronic.
