Standart Zinc Flake

Standart zinc flakes provide very good surface protection and good cathodic corrosion protection even at low levels of pigmentation. Standart® Zinc Flake AT and Standart® Zinc Flake GTT are platelet pigments consisting of metallic zinc, providing excellent corrosion protection properties for powder coating primers. Apart from offering cathodic corrosion protection, their lamellar structure provides an additional barrier effect in the powder coating film, resulting in a significantly reduced permeability to corrosive agents. For the production of zinc-based powder coating primers, Zinc Flake AT or Zinc Flake GTT (10%–15%) are added with the other anti-corrosive pigments (40%– 60%) at the premix stage, followed by extruding, grinding and sieving.
