Calcium phosphate is an inorganic white pigment; it is used in paints and vanishes to improve anti-corrosion properties and adhesion strength. Due to a lamellar structure of pigment particles, a barrierlayer effect of the coating is enhanced on anode area.


• Non-toxic, does not contain heavy metals and compounds

• Effective corrosion resistance

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

• Quick drying and excellent water resistance

• Low requirements to a surface to be covered

• Strong bond between paint and a surface

• Good retention on a 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 color bendability. Good corrosion resistance.

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