Epoxy Has Outstanding Electrical Properties and Chemical ResistanceMaster Bond EP17HT-3 is a one-part epoxy that sets up in 20 to 30 seconds and snap cures in only 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 ¼ in. 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 excellent electrical insulation and chemical resistance characteristics. It is resistant to a wide 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 2,100 psi.

Master Bond's EP17HT-3 adhesive has superior 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 that is ideal for bonding dissimilar substrates and applications subject to thermal cycling. Each product comes in half pints, pints, quarts, gallons, and 5 gallon container sizes.
