Product Description

SEM 40793 CopperWeld™ is a copper-based weld-through primer that provides corrosion protection on bare metal surfaces that will be resistance spot welded during collision repair. Applied to mating surfaces before welding, CopperWeld conducts electricity for consistent weld quality while protecting the joint from corrosion.

Key Features:

  • Copper-Based Formula: Conductive coating allows resistance spot welding through the primer.
  • Corrosion Protection: Protects weld joints and mating surfaces from rust.
  • Pre-Weld Application: Apply to bare metal before spot welding for protected joints.
  • 16 oz Aerosol: Quick, even coverage on mating flanges and panels.
  • OEM Requirement: Weld-through primer is specified by most vehicle manufacturers for structural repairs.
