J-B Weld High-Heat Epoxy Putty - 8297

Restore heat-exposed parts with a moldable repair compound with this universal/spec-match J-B Weld High-Heat Epoxy Putty - 8297. This high-heat epoxy putty is designed for repairs on metal and other compatible surfaces that see elevated service temperatures.

8297 is J-B Weld HighHeat, a universal/spec-match epoxy putty used for patching and rebuilding heat-exposed components where standard epoxy may not be the best choice. It is commonly used on metal repair areas that need a hand-moldable material before sanding, filing, or finishing.

Compatibility: Heat-exposed metal repair applications and compatible shop or appliance-adjacent surfaces where a high-temperature epoxy putty is appropriate.

Please confirm the intended application, surface material, cure time, and temperature exposure before ordering.

Is it time to replace?

• Common Symptoms: Cracks, pinholes, chipped areas, or damaged surfaces on components exposed to higher temperatures.
• Visible/Sensory Cues: Heat-related material loss, visible cracks, leakage through a damaged spot, or a surface that needs rebuilding.

Pro Tip: Shape the repair before the putty firms up, because high-heat putties are much easier to finish when the initial form is close to final.
