Product Introduction: HH-608 Nano Phosphate-Free Ceramic Coating Agent

HH-608 nano phosphate-free ceramizing agent is a phosphate-free, reactive pretreatment chemical that is environmentally friendly, free of phosphates and heavy metals, and compliant with the EU RoHS environmental protection requirements. It is designed for surface film-forming treatment of steel parts, aluminum materials, electrolytic plates, galvanized sheets, aluminum alloys, and other substrates, enhancing coating adhesion and corrosion resistance. The product is non-volatile and does not precipitate, making it suitable for spray or dip treatments at room temperature. After treatment, a highly stable coating layer is formed, which strengthens the bond between the coating film and the substrate and improves the corrosion resistance of the coated surface.
