Applications of Diammonium Bis[Carbonato-O]Dihydroxyzirconate in Industrial Manufacturing

Diammonium bis[carbonato-O]dihydroxyzirconate serves as a zirconium-based precursor with high reactivity, solubility, and stability, supporting specialized use in coatings, advanced ceramics, catalyst manufacturing, and electronic component production. Our factory produces and supplies this chemical with tight process controls, enabling demanding downstream processes for industrial customers worldwide.

1. High-Performance Anti-Corrosion Coating Systems

Major coating formulators use diammonium bis[carbonato-O]dihydroxyzirconate as a key zirconium source in waterborne and solventborne conversion coatings. This ingredient facilitates superior adhesion promotion and long-term corrosion resistance, particularly for steel and galvanized substrates. It integrates into low-VOC pretreatment chemistries replacing toxic chromates, meeting automotive, appliance, and architectural sector needs. Our customers dose this additive with controlled pH and mixing procedures at specific process stages to form uniform zirconia-containing conversion layers before painting or powder coating steps.
