Zincweld provides excellent corrosion protection in areas where metal panels will be welded together. Its zinc-based formula helps protect bare metal surfaces in locations that may become difficult to access after welding.

The formula also offers enhanced adhesion to bare metal. In addition, SEM designed the coating to resist flaking and peeling. These characteristics make it useful for professional collision repair, panel replacement, and automotive restoration.

Designed for Bare Metal

SEM specifies bare metal as the suitable substrate for Zincweld. Clean and prepare the bare metal thoroughly before application.

According to SEM‘s technical data sheet, the recommended preparation includes cleaning the surface, sanding with P80 grit, removing dust, and cleaning the surface again. The surface must be bare metal before applying the product.

Excellent Corrosion Protection

One of the main advantages of Zincweld is its zinc-rich protective formula. It helps provide corrosion protection between welded substrates while maintaining efficient welding performance.

Furthermore, the coating helps minimize the heat-affected zone during welding. Its low-spatter formulation also helps create a cleaner welding process
