Master Bond's EP17HT-3 one-part snap curing epoxy features high temperature resistance
Master Bond EP17HT-3 is a one-part epoxy that sets up in 20 to 30 seconds and snap cures in two to three minutes at 250°F-300ºF. As a one-part system, no mixing is required, and the epoxy can be cured in sections up to 1/4 inch thick. Moreover, its working life is indefinite. as it will not gel until heated above 200ºF.
With a volume resistivity of greater than 1014 ohm-cm, EP17HT-3 has electrical insulation and chemical resistance characteristics. It is resistant to a range of chemicals, including water, oil and most organic solvents. Other typical features include a Shore D hardness that exceeds 85 and a tensile lap shear of 2100 psi.
Master Bond's EP17HT-3 adhesive has improved temperature resistance with a service operating temperature range of -60ºF to +400ºF. It is 100% reactive and contains no solvents or diluents. It is also available in a paste version called EP17HT-3ND and a slightly toughened variant called Supreme 17HT-3, which is well suited for bonding dissimilar substrates and applications subject to thermal cycling. Each product comes in half pints, pints, quarts, gallons and five-gallon container sizes.
