product description:

1, zinc phosphate is anti-rust anti-corrosion effect of a new generation of non-toxic, pollution-free anti-rust paint.

2, it can effectively replace the heavy metal lead, chromium, the traditional anti-rust paint, paint industry is to replace or reduce lead, chromium toxic pigments ideal antirust paint.

3, zinc phosphate in the trivalent iron ions have a strong ability to condensation, the zinc phosphate and iron ions and the reaction of iron, can form a strong iron phosphate as the main protective film, this dense passivation film is not soluble in water , high hardness, strong adhesion, with a lot of metal ions to produce chromium compounds, with good anti-rust effect. the coating made with zinc phosphate has excellent anti-rust performance.

specifications :

applications:

zinc phosphate can be used in a variety of paint-based paint for the preparation of a variety of water, acid, anti-corrosion coatings such as: phenolic paint, epoxy paint, acrylic acid paint, alkyd paint and water-soluble resin paint, ships, automobiles, trains, industrial machinery, light metals, household appliances and food with metal containers and other aspects of anti-rust paint, but also for the production of chlorinated rubber and synthetic polymer flame retardant.

1, zinc phosphate does not contain lead, chromium and other metals, non-toxic, non-polluting. the skin does not stimulate the role of good thermal stability, anti-rust ability, in the paint with less, low cost.

2, the pigment is white, so according to the need for color matching, which can simplify the painting process, painting process.
