Product Description

Zinc Phosphate is an inorganic zinc salt commonly supplied as a white, odourless powder. It is also known as Zinc Orthophosphate, Trizinc Diphosphate and Pigment White 32. The compound has the CAS number 7779-90-0, molecular formula Zn₃(PO₄)₂ and molecular weight 386.11 g/mol.

Zinc Phosphate is widely associated with corrosion-resistant coatings, metal-surface treatment, primer pigments and laboratory research. It may be used in coating formulations and industrial processes where a zinc-based phosphate compound is required. PubChem identifies corrosion inhibition, pigments, fillers, surface modification and plating-related applications among its reported uses.

This 500 g product may be supplied under Loba, Research Lab or Merck branding, depending on stock and customer requirements. Loba Chemie officially lists Zinc Phosphate Extra Pure in a 500 g pack under article number 6552A.

Product Overview

Zinc Phosphate is a zinc salt of phosphoric acid. Its structure contains three zinc atoms and two phosphate groups. It is generally encountered as an inorganic solid and may be supplied as powder, powder-and-chunk material or other manufacturer-specific forms.

One of the best-known uses of Zinc Phosphate is as a corrosion-inhibiting pigment in primers and protective coatings. It can be incorporated into coating systems designed to protect metal surfaces from corrosion. Zinc Phosphate is also associated with phosphate conversion coatings and metal-surface preparation processes.

For laboratory use, the correct grade should be selected according to the intended procedure. Purity, zinc content, particle characteristics, loss on ignition and trace-metal content can differ significantly between general laboratory, Extra Pure and high-purity products.

Main Applications

Corrosion-Resistant Coatings

Zinc Phosphate is commonly used as a corrosion-inhibiting pigment in primers, paints and protective coating systems for metal surfaces.

Metal-Surface Treatment

It may be used in phosphate-conversion and metal-surface preparation processes designed to improve corrosion resistance or support subsequent coating application.

Paint and Primer Formulation

Zinc Phosphate can be incorporated into selected industrial primer and coating formulations as a pigment, filler or corrosion-inhibiting component.

Laboratory Research

The product may be used in inorganic chemistry, material science, surface chemistry and chemical-characterisation studies.

Quality-Control Testing

Industrial laboratories may use Zinc Phosphate as a reference material, formulation ingredient or test sample where the documented method requires it.

Materials Development
