High Temperature Project

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 400ºF and intermittent heat exposure to 550ºF
