Two Component, Low Viscosity Epoxy Features Outstanding Chemical Resistance

Press release date: May 15, 2017

Master Bond EP62-1BF is a two part epoxy featuring the ability to withstand exposure to aggressive chemicals including acids, bases and solvents, even at high temperatures. “We tested the chemical resistance properties of EP62-1BF by taking cured samples of the system and immersing them in a variety of chemicals, like sulfuric acid, toluene, ammonium hydroxide, etc.,” said Venkat Nandivada, manager of technical support. “Even after six months, the samples weren’t affected by chemicals.”

EP62-1BF is easy to handle with a long open time of 12-24 hours at 75°F for a 100 gram batch. It has a non-critical mix ratio of 100 to 5 by weight and offers a variety of cure schedules at moderately elevated temperatures from 140-257°F [60-125°C]. With a mixed viscosity of 2,000-5,000 cps, EP62-1BF can be used for potting small components. Additionally, it has low shrinkage upon curing.

After curing, this compound delivers an impressive strength profile with a tensile lap shear strength of 2,000-2,200 psi, a tensile strength of 8,000-9,000 psi and a tensile modulus of 500,000-550,000 psi. EP62-1BF is thermally stable and has a glass transition temperature (Tg) of 125-135°C and is serviceable over the wide temperature range of -60°F to +400°F [-51°C to +204°C]. This formulation is also a competent electrical insulator with a volume resistivity exceeding 10^14 ohm-cm.

Its combination of chemical resistance, thermal stability and physical strength properties enable this product to be used for many applications in the aerospace, electronic and specialty OEM industries. EP62-1BF is available for use in ½ pint, pint, quart, gallon and 5 gallon container kits, as well as premixed and frozen syringes.
