Wayncor™ 222 – Corrosion Inhibitive Pigment
Zinc Phosphate
Wayncor™ 222 is a white, non-refractive, anti-corrosive pigment used in protective coatings. It is widely considered by the coatings industry to be a standard corrosion inhibitor. It exhibits a high degree of versatility and is compatible with almost all commercially available aqueous and solvent based coatings. The use level will vary depending upon resin system, pigment volume concentration and desired performance parameters, however typical use levels are between 3 – 10% total formula weight.
