About this item

J-B Weld HighHeat is a hand mixable epoxy putty stick specifically formulated to bond and repair materials that will be exposed to high temperatures in automotive and industrial maintenance applications. It cures to a tough, hard bond with little to no shrinkage. This industrial-strength product outperforms conventional epoxy putties at high temperatures and sets in 1 hour at room temperature. After 8 hours, it can be drilled, tapped, machined, ground, filed and painted. HighHeat is rated at a tensile strength of 800 PSI and cures to a machine grey in color. It is able to withstand continuous heat exposure of 400°F and intermittent heat exposure to 550°F. Hand mixable epoxy putty stick specifically formulated to bond and repair materials that will be exposed to high temperatures. Great for exhaust manifolds, tail pipes, mufflers, engine blocks, machinery and other high temperature projects. Sets in 1 hour at room temperature, functionally cures in 8 hours and withstands continuous heat of 400F (550F intermittent) Once cured, it forms a permanent bond and can be drilled, tapped, machined, ground and filed.
