Calcium phosphate is an inorganic white pigment; it is used in paintwork products to enhances anti-corrosion properties and adhesion strength. Thanks to the lamellar structure of the pigment particles, the barrier-layer effect of the coating is enhanced on the anodic area.


- Non-toxic, environmentally friendly product

- Effective corrosion resistance

- No emission of toxic gases when covered with steel plates for welding

- Quick drying and excellent water resistance

- Low requirements to the surface to be covered

- Strong bond between the paint and the surface

- Good retention on the base in form of coating


It is suitable for paints, resins, epoxy resins, polyurethanes, amino acids, acrylates, rubber. Due to low refractive power it can be used for finishing paints and primers. Easy colour bendability. Good corrosion resistance.

We can always offer you the required amount of zinc phosphate KRONPHOS CP, large volumes of the product are supplied at a discounts.
