📌 Product Description

Copper Phosphate is an inorganic copper salt known for its chemical stability, corrosion-inhibiting properties, and controlled copper ion release. It is mainly used in industrial coatings, metal surface treatment systems, and specialty chemical applications. By forming a protective phosphate layer on metal substrates, Copper Phosphate helps reduce corrosion and improve coating durability. Its characteristic blue-green color also makes it suitable for use in functional and specialty pigment formulations.

🏭 Applications

🛡️ Anti-Corrosion Pigment for Industrial Coatings
Copper Phosphate is used as a functional anti-corrosion pigment in industrial primers and protective coatings. It contributes to corrosion inhibition by forming a stable phosphate barrier on metal surfaces, reducing the effects of moisture, oxygen, and aggressive environments. It is suitable for steel structures, machinery, and industrial equipment.

🎨 Specialty Coatings and Functional Pigments
Due to its distinctive blue-green color and chemical stability, Copper Phosphate is applied in specialty coating formulations where both functional performance and aesthetic appearance are required. It can be used in decorative industrial coatings and technical pigment systems.

🧪 Metal Surface Treatment and Pretreatment Systems
Copper Phosphate is applied in metal surface treatment formulations to enhance coating adhesion and corrosion resistance. It is used in phosphate-based pretreatment systems prior to painting or coating, especially for iron and steel substrates.

⚙️ Industrial and Chemical Processing Applications
In chemical manufacturing and laboratory applications, Copper Phosphate serves as a copper source in controlled-release systems, catalysts, and specialty chemical formulations where stability and low solubility are important.

🌿 Antifouling and Biocidal-Related Industrial Uses
Because of the presence of copper ions, Copper Phosphate is sometimes used in industrial formulations requiring antimicrobial or antifouling performance, such as marine-related coatings and technical materials, subject to local regulatory approval.
