KRONPHOS PZC zinc phosphate contains an optimal ratio of zinc, phosphorus and calcium. Presence of an additional element in the formula is proven to provide long-term protection against corrosion..


- 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-based coating demonstrates a lasting anti-corrosion effect


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 PZC, large volumes of the product are supplied at a discounts.
