High-Temperature Anti-Seize & Assembly Spray | NZ

The Würth Copper Spray CU 800 is a high-performance anti-seize spray designed to protect metal components exposed to extreme heat, pressure, and corrosive environments. It forms a copper-based protective layer that prevents seizing, galling, and corrosion — making future disassembly easier.

Used across automotive and fabrication workshops in New Zealand, CU 800 is ideal for exhaust systems, brake components, bolts, studs, flanges, and threaded fasteners. It withstands very high temperatures and harsh conditions without burning off or washing away.

If it gets hot, lives outside, or needs to come apart again, this is what you use.
