Thin-layer primer with very good adhesion to steel, iron and galvanized substrates. Mipa Weld-Primer is suitable for many welding processes such as MIG, TIG or spot welding. Due to the very fast drying time, welding work can begin shortly after application. The very high proportion of active pigments ensures very high corrosion protection and covers even thin layers. With the zinc variant, the corrosion protection properties on iron and steel are higher, while the Mipa Weld-Primer copper has a higher conductivity.
