product introduction

Our Modified Phosphate is a non-toxic, harmless, white, rust-preventive pigment. It is primarily used in water-based industrial anti-corrosion coatings, steel structure corrosion protection, automotive component primers, and general industrial maintenance coatings.

Anticorrosive Zinc Phosphate pigment

Zinc Aluminum Phosphate (SZPA): Since it does not contain alkaline components,ensuring enhanced stability. Its primary applications include industrial anti-corrosion coatings, steel structure protection, and general industrial maintenance.

Organically Modified Phosphate (SZPO): This variant delivers superior rust prevention through superior compatibility and adhesion with resin systems, resulting in a more integral and resistant coating film.

Molybdenum-Modified Zinc Phosphate (SZMP): It utilizes a synergistic effect between molybdate and phosphate ions for top-tier rust inhibition，Achieve superior rust prevention in resin systems.

Advantage&Application:

The coatings prepared with Modified Phosphate have excellent antirust performance and water resistance, and are used in various paint-based coatings, for preparing various water-resistant, acid-resistant and corrosion-resistant coatings, such as phenolic paint, epoxy paint, acrylic acid paint, alkyd paint and water-soluble resin paint, antirust paints for ships, automobiles, industrial machinery, light metals, household appliances and metal containers for food.
