Description

Zinc Phosphate, Monobasic is an inorganic salt with the chemical formula Zn(H₂PO₄)₂. This compound serves as a critical source of zinc and phosphate ions, valued for its role in corrosion inhibition and as a nutrient precursor. It is primarily utilized by manufacturers in the coatings, agriculture, and specialty chemical industries for formulating corrosion-resistant primers, micronutrient fertilizers, and flame-retardant additives.

Application

• Corrosion-Inhibiting Pigments: A key component in zinc phosphate primers and anti-corrosive coatings for metals, including steel and aluminum, in automotive, marine, and industrial maintenance applications.
• Micronutrient Fertilizers: Acts as a controlled-release source of both zinc and phosphorus in agricultural formulations to correct soil deficiencies and promote plant growth.
• Dental Cements: Used in the formulation of zinc phosphate dental cements for permanent luting of crowns, inlays, and orthodontic appliances.
• Flame Retardant Synergist: Employed as an additive in polymers and plastics to enhance flame retardancy, often in combination with other compounds.
• Laboratory Reagent: Serves as a chemical reagent in analytical chemistry and research for phosphate buffer preparation and specific synthesis processes.
• Metal Surface Treatment: Used in conversion coatings and phosphating processes to prepare metal surfaces for painting or enhance paint adhesion.
