Description

Specialist Headlight Repair Primer

Würth PC Adhesion Agent is a colourless 1C primer formulated for use in the restoration of damaged headlight diffusers. By improving adhesion between the sanded polycarbonate lens and the finishing clear coat, it ensures a long-lasting, durable repair that restores optical clarity and surface protection.

Consistent Application

The spray system delivers a wide beam pattern with constant atomisation pressure, allowing for smooth, streak-free coating and efficient coverage. This guarantees a high-quality finish that meets professional repair standards.

Repair System Integration

The PC Adhesion Agent is an essential step in the headlight refurbishment process, acting as the bonding layer before clear varnish application. For full protection against UV damage and weathering, headlights should be finished with Würth Rapid 2C Clear Varnish (art. no. 5867 000 124).

Fast and Reliable Process

Applied in just 1.5 spray passes, the primer dries with a flash-off time of 40 minutes at 20°C, making it efficient for workshop use. The result is a stable, receptive surface that ensures lasting adhesion of the protective topcoat.
