HALOX® Zinc Phosphate

HALOX® Zinc Phosphate is a white, non-refractive, corrosion-inhibiting pigment that is widely used in protective coating systems. It is also known as zinc phosphate-dihydrate and is characterized by a narrow particle size distribution, with an upper particle size limit of 10 microns and a mean particle size of 5 microns. This pigment is highly versatile and serves as a standard corrosion inhibitor for most high-performance resin systems, including vinyl, chlorinated rubbers, and epoxies. It is especially recommended for high acid-value resins, catalyzed baking systems, and vinylidene chloride latexes. In addition, HALOX® Zinc Phosphate is an ideal choice for thin film applications (less than 1 mil or 25 microns). It meets the ASTM D 6280-98 specification for zinc phosphate pigment type I and is widely used in the industry.
