Tyzor® 217 is an aqueous chelate based on zirconium. It is used as a cross-linker and an adhesion promoter in coatings, inks, and adhesives and a cross-linker for fracturing fluids
Tyzor® 217 is a water-based zirconium chelate compound. It is stable at neutral pH and is recommended for use in water-based formulations. Tyzor® 217 provides utility in many different applications because it will react with various chemical groups, including hydroxyl groups, carboxyl groups, and other nucleophiles. Thus, it is an ideal cross-linking agent and adhesion promoter for functionalized polymers used in coating, ink, and adhesive applications. Tyzor® 217 can also be used to treat surfaces like glass and metal to improve adhesion of paints and coatings. In the oil well industry, Tyzor® 217 is used to cross-link materials such as guar gum and other carbohydrates to form high-viscosity gels from fracturing fluids. In addition, Tyzor® 217 is used to treat paper and textile surfaces to increase hardness and improve hydrophobicity.
