CAS Number
7757-93-9
EC Number
231-826-1
Chemical Name
Calcium Hydrogen Phosphate

Kronphos CP 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.
