J-B Weld 8297 HighHeat Epoxy Putty - 57g

J-B Weld 8297 HighHeat Epoxy Putty - 57g • High-Temp • Water & Oil-Resistant • Epoxy Putty

J-B Weld 8297 HighHeat Epoxy Putty is a high-temperature, hand-mixable epoxy stick designed specifically for demanding automotive and industrial maintenance tasks. This 57 g (2 oz) epoxy putty delivers a tough, hard bond with virtually no shrinkage, setting in just 1 hour at room temperature and fully curing in 8 hours. Once cured, it becomes machinable—drillable, tappable, sandable, grindable, and paintable—offering exceptional versatility for permanent repairs.

It withstands continuous temperatures up to 232 °C (450 °F) and intermittent peaks up to 260 °C (500 °F), and maintains a strong bond even under harsh exposure to water, chemicals, and oil. With a shear strength of 800 PSI at ambient and 600 PSI at elevated heat, this epoxy outperforms conventional putties in extreme environments. Machine-grey when dry and manufactured in the USA, J-B Weld HighHeat is the go-to solution for fixing exhaust systems, engine components, mufflers, and industrial equipment subjected to extreme heat.:contentReference[oaicite:0]{index=0}
