Copper Anti-Seize for High-Temperature Assembly

Loctite 234207 is a copper-based paste designed to prevent seizure, galling and corrosion on threaded fasteners and press-fit parts. It suits automotive, industrial and maintenance crews who need a lubricant that stays effective from -20 °F up to 800 °F.

Consistent protection through thermal cycling

The paste maintains its lubricating film during repeated heating and cooling rather than breaking down in a single high-heat event. Its non-flammable formulation resists evaporation and carbonisation, so bolts torqued today can still be removed after extended service at the upper temperature limit.

Bulk can for workshop-scale use

The 8 lb container provides enough volume for daily application on exhaust studs, manifold bolts and brake hardware without frequent reordering. Wide-mouth packaging allows brush or spatula access, and the copper colour gives immediate visual confirmation of coverage on dark metal surfaces.

Questions about this item

Does the copper paste stay stable when engine parts reach 800 °F during long runs?

The paste is rated from -20 °F to 800 °F, so it will not break down or carbonise at sustained high temperatures.

What thread size or tool do I need to open and reseal the 8 lb can?

The can uses a standard friction-fit lid; no special tool or thread adapter is required to open or close it.

Will the paste protect steel bolts that have been in service for decades without causing galvanic corrosion?

Copper-based anti-seize is compatible with ferrous fasteners and prevents seizure on aged steel hardware.
