protect against corrosion with zinc phosphate

10/28/2014

Zinc Phosphate is a principal raw material that gives paints and coatings anti-corrosive properties. Originally, zinc phosphate was used as a non-toxic alternative to zinc chromate and red lead. It is used in anti-corrosive paint primer systems, especially those based on solvent borne Epoxy-Polyamide, Chlorinated rubber, Alkyd and Polyurethane resins and water based systems. Delaphos is the only zinc phosphate producer in the UK. They offer the purest white phosphate with no yellowing and high opacity in the following four grades:

Delaphos® 2

(D2) di-hydrate ZN₃(PO₄)₂. 2H₂O

Delaphos® 2M

(D2M) di-hydrate micronized ZN₃(PO₄)₂2H₂O

The smaller average particle size makes the micronized grade Delaphos® ideal for rapid dispersion in production processes.

Delaphos® 4

(D4) tetrahydrate ZN₃(PO₄)₂. 4H₂O

Produced in the non-hygroscopic form and has a shelf life in excess of 1 year.

Delaphos® 4M

(D4M) tetrahydrate micronized ZN₃(PO₄)₂4H₂O

Delaphos has earned the reputation of providing cost-effective, high purity Zinc Phosphate. Standard packaging for Zinc Phosphate is 55.12 lbs. or 2204 lbs. supersac. Custom packaging is also available.
