Designed to bond and seal against liquids, gasses and common automotive fluids, Permatex 500° High Heat is ideal for a wide variety of applications in engine compartments, engine block and exhaust components, where temperatures can easily exceed 400° F (204° C). The innovative epoxy has a holding strength of 2,500 PSI. It sets in just 10 minutes and has a two-hour cure time.

Permatex R&D Director Antoine Phillips developed the 500° High Heat Epoxy formulation and noted the challenges his team had to overcome in creating an epoxy which exceeded industry standards. “Developing this specialized epoxy required the use of unconventional materials and processes to produce a formulation that was not feasible with traditional stick and putty epoxies. Our solution was the use of a multi-functional chemistry to deliver a dense, high strength, highly crosslinked temperature resistant adhesive that could perform effectively at extremely high temperatures,” added Phillips.

In some cases, it can be used in place of welding or brazing.
