Description

Zinc Orthophosphate is an inorganic salt widely recognized for its role as a corrosion-inhibiting pigment and a source of zinc and phosphate ions. This compound is valued for its ability to form protective layers on metal surfaces, significantly extending the lifespan of coated materials. It is a critical raw material for formulators in the paints & coatings, metal treatment, and ceramics industries seeking effective, non-toxic anti-corrosion solutions.

Application

• Corrosion-Inhibiting Paints & Primers: A key component in anti-corrosion coatings for automotive, marine, and industrial steel structures.
• Metal Pretreatment & Conversion Coatings: Used in phosphating processes to prepare metal surfaces for painting or powder coating.
• Dental Cements & Composites: Serves as a reinforcing agent and provides therapeutic ions in certain dental material formulations.
• Ceramic Glazes & Glass Production: Acts as a flux and opacifier, contributing to the durability and finish of ceramic products.
• Fire Retardant Additives: Incorporated into polymers and materials to enhance fire resistance properties.
• Nutrient Supplement in Animal Feed: Provides essential zinc and phosphorus in mineral premixes for livestock nutrition.
• Laboratory Reagent & Analytical Chemistry: Used as a standard or reactant in various chemical synthesis and analytical procedures.
