Norton NRV.91000 Zinc Weld-Thru Primer

The Norton NRV.91000 Zinc Weld-Thru Primer is a specialized coating designed to protect metal surfaces from corrosion while maintaining electrical conductivity during welding operations. This professional-grade primer is formulated with a high concentration of zinc to provide superior rust and corrosion protection on bare metal surfaces that will be welded.

Key Features:

• High zinc concentration for maximum corrosion protection on welded joints
• Excellent electrical conductivity for resistance spot welding, MIG welding, and TIG welding
• Allows welding through the coating without compromising weld quality
• Protects bare metal from flash rust and corrosion during fabrication
• Ideal for automotive body repair, metal fabrication, and collision repair applications

This weld-through primer creates a protective barrier that prevents oxidation between the time of metal preparation and final coating, while still allowing electrodes and welding arcs to pass through effectively. Perfect for professional body shops and fabricators who need corrosion protection without sacrificing weldability.
