🧾 Product Description

Copper Hydrogen Phosphate is an inorganic copper phosphate compound designed for industrial corrosion control, surface treatment, and functional coating systems. It provides controlled copper ion release combined with phosphate passivation, helping to improve corrosion resistance and surface stability of metal substrates. Compared with copper orthophosphate, it exhibits higher chemical activity and better compatibility in phosphate-based formulations, making it suitable for advanced industrial applications.

🏭 Applications

🛡️ Anti-Corrosion Industrial Coatings
Used as a functional anti-corrosion additive or pigment in industrial primers and protective coatings. Copper Hydrogen Phosphate forms a phosphate passivation layer on metal surfaces while releasing copper ions in a controlled manner, effectively reducing corrosion caused by moisture, oxygen, and aggressive industrial environments.

🧪 Metal Surface Treatment & Phosphating Systems
Applied in phosphate-based metal pretreatment formulations prior to painting or powder coating. It enhances surface activation, improves coating adhesion, and increases long-term corrosion resistance, especially for steel and iron substrates.

🎨 Specialty & Functional Coatings
Suitable for specialty coating systems requiring both functional performance and visual differentiation. Its stable structure and blue-green color make it useful in technical coatings for machinery, equipment housings, and industrial components.

⚓ Antimicrobial & Antifouling-Related Industrial Uses
Due to the presence of copper ions, Copper Hydrogen Phosphate is applied in industrial formulations where antimicrobial or antifouling performance is required, such as marine-related coatings and technical materials, subject to local regulatory approval.

⚙️ Industrial Chemical & Technical Applications
Acts as a controlled copper source in chemical processing, catalysts, and specialty formulations where low solubility, gradual copper release, and high stability are required.
