Our Black Zinc Passivate is essential for post-plating protection, increasing corrosion resistance and giving a dark black colour. With the black passivate we include 5 litres worth of Rogard Supreme Seal 500


Rogard is used to seal the passivate after application, it also helps to prevent wear and will nearly double the corrosion protection. It can be used on most types of trivalent and hexavalent passivate.
