Fluorozirconic acid

Fluorozirconic acid (CAS 12021-95-3 ), also known as hexafluorozirconic acid, is an inorganic acid used industrially as a surface treatment and metal finishing agent. It deposits zirconium-based conversion coatings on metal substrates. This chemical provides corrosion resistance and adhesion promotion without chromium-based chemistry. In metal pretreatment, it forms thin zirconium oxide conversion coatings on aluminum, steel, and galvanized surfaces prior to painting. It serves as a direct chromate-free alternative increasingly required by automotive and appliance OEMs. Electronics manufacturers use it for etching and surface conditioning of metal components where controlled oxide layer formation is critical. The acid is essential to downstream bonding processes in high-tech manufacturing. In water treatment, it functions as a pH-regulating and complexing agent in specific process streams to maintain chemical balance. Textile and leather processors apply it as a fixing and surface modification agent to improve fiber bonding and finish durability. This versatility makes it a staple in modern industrial chemical inventories. Fluorozirconic acid is supplied as an aqueous solution, with 45% concentration being the most commonly traded commercial form. Technical grade is the standard market offering for most industrial applications. Concentration and purity specifications vary by application requirement to meet specific client needs. Bulk liquid supply in IBC containers or drums is the typical packaging format for industrial buyers globally. Contact us for supply of Fluorozirconic acid Request Quote
