REACH certified


Zinc phosphate of PZ class has established itself as a reliable anticorrosive product. High zinc content allows adding less pigment to obtain excellent anticorrosive properties of paint and coatings. The color brightness of 99% proves purity of the product and enables to use the anti-rust pigment of PZ class in more complex compounds. Unlike organic corrosion inhibitors, the film coating exhibits a longlasting anticorrosive effect.


- Non-toxic, environmentally friendly product

- Being free of unwanted colour, the product can be used in primers and ground coats of any colour

- When introduced into a painting system, the product does not cause side effects

- When the coating composition with zinc phosphate is applied on the metal surface, a protective layer is created on the surface of the substrate, which interacting with oxygen creates phosphate complexes, protecting the metal from rusting

- Unlike organic corrosion inhibitors, the film coating exhibits a lasting anti-corrosion effect


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

We can always offer you the required amount of KRONPHOS PZ; large volumes of the product are supplied at discounts.
