Powder coating primer
Product Description
MT-Active is a powder coating primer, totally free from Zinc. It is designed to give enhanced corrosion protection of mild steel and is an epoxy-polyester primer including active anticorrosive pigments. The addition of these pigments provides a steel passivation effect to protect the substrate enhancing the performance when compared to other non-active systems.
