NINGBO INNO PHARMCHEM CO., LTD. is proud to supply Ammonium Zirconium Carbonate (AZC), a chemical that offers significant advantages due to its unique chemical properties and reaction mechanisms. Understanding how AZC works is key to appreciating its broad utility in applications such as paper coatings, inks, and adhesives. As a leading manufacturer in China, we are committed to providing products backed by scientific understanding.

AZC is an aqueous alkaline solution containing anionic hydroxylated zirconium polymers. Its efficacy as a crosslinker stems from its ability to generate reactive zirconium cations during drying processes. When incorporated into formulations containing binders with functional groups like carboxyl (-COOH) and hydroxyl (-OH), AZC facilitates crosslinking. The process begins with the coordination of zirconium to these functional groups. As water evaporates and the pH shifts slightly during drying, AZC undergoes a decomposition process. This decomposition releases carbon dioxide and ammonia, and importantly, it generates positively charged zirconium species.

These zirconium cations then form strong, covalent bonds with the functional groups on the binder molecules. This irreversible chemical reaction creates a stable, crosslinked network. The strength and durability imparted by this crosslinking are significant advantages, particularly in applications requiring high water resistance and improved adhesion. For instance, in paper coatings, this crosslinking prevents the binder from dissolving when exposed to moisture, thereby improving printability and the overall integrity of the coating. The speed of this reaction, occurring during the standard drying stages of most industrial processes, makes AZC a highly efficient additive.

The formaldehyde-free nature of AZC is a critical aspect of its chemical design, offering a safer and more environmentally friendly alternative to traditional crosslinking agents.
