Master Bond Snap-Cure Epoxy Resists Chemicals

Master 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 to 300F (121 to 149C). As a one part system, no mixing is required and the epoxy can be cured in sections up to 1/4in (6.35mm) thick. Moreover, its working life is indefinite as it will not gel until heated above 200F. With a volume resistivity of greater than 1014ohm-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 2100lb/in2. Master Bond's EP17HT-3 adhesive has superior temperature resistance, with a service operating temperature range of -60F to +400F. It is 100 per cent 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 ideal for bonding dissimilar substrates and applications subject to thermal cycling. Each product comes in half pints, pints, quarts, gallons and five-gallon container sizes. Master Bond's EP17HT-3 one-part snap-curing epoxy features high-temperature resistance and has outstanding electrical properties and chemical resistance.
