Features & Benefits

CASE Ingredients Features
Features
  • Non-toxic, environmentally friendly product
  • Being free of unwanted color, the product can be used in primers and ground coats of any color
  • 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

Applications & Uses

Compatible Substrates & Surfaces
Application and Uses
  • 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 KRONPHOS PZA, large volumes of the product are supplied at a discount
  • Type of use: anticorrosive pigment (solid corrosive inhibitor)
