High heat 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. High heat 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 400F and intermittent heat exposure to 500F. Great for use on exhaust manifolds, tail pipes, mufflers, engine blocks, duct work, machinery, and high temperature project.
