This two-component primary zinc epoxy-based wash primer can be applied to properly prepared ferrous and non-ferrous metals. It’s formulated to offer maximum corrosion resistance, providing localized cathodic protection specifically over ferrous steel. Additionally, it enhances adhesion on stainless steel and aluminum surfaces when grit-blasting is not possible. Always top coated with NP-9500 primer, it ensures optimal performance, with effectiveness depending on the level of surface purity and mechanical preparation.
