SUNOX® EXTREME Copper Weld Aerosol 500ml
SUNOX® EXTREME Copper Weld Aerosol 500ml
Professional Copper-Rich Weld Through Primer – Superior Conductivity & Corrosion Protection
SUNOX® EXTREME Copper Weld is a premium copper-rich weld-through primer designed to provide outstanding corrosion protection and electrical conductivity during welding operations. Developed for automotive bodyshops, vehicle restoration, fabrication and industrial applications, it allows welded joints to be protected before assembly whilst maintaining excellent weldability.
The advanced copper-rich formulation creates a highly conductive coating that can be welded directly through, making it ideal for protecting seams, flanges, lap joints and concealed metal surfaces that become inaccessible after assembly.
Widely used in professional automotive repair environments, SUNOX EXTREME Copper Weld helps improve the longevity of repairs by protecting vulnerable metal surfaces from corrosion before welding takes place.

Why Use Copper Weld Primer?
When panels are assembled and welded together, many metal surfaces become inaccessible for future corrosion protection. SUNOX EXTREME Copper Weld helps:
• Protect concealed metal surfaces
• Improve corrosion resistance in welded joints
• Maintain excellent weld conductivity
• Reduce future rust formation
• Increase repair longevity
• Improve protection of lap joints and seams
Typical Automotive Uses
• Quarter panel replacement
• Sill repairs
• Floor pan installation
• Door skin replacement
• Chassis repairs
• Inner panel repairs
• Restoration and fabrication work
Important Information
• Apply to clean, bare metal surfaces prior to assembly and welding.
• Allow the coating to dry before commencing welding operations.
• Use appropriate welding techniques and PPE at all times.
• Following welding, exposed areas should be protected using suitable primers, seam sealers and paint systems where required.
