Tyzor® 223

Zirconium chelate with approximately 31% active ingredient in mixed alcohol solution. Is an organometallic catalyst. It is not affected by freezing and thawing. It is compatible with water, offers low color generation and works well over a wide pH range. It reacts with water by hydrolysis to form a reactive hydroxy zirconium chelate that is stable in water for extended periods. The original or hydrated chelate bonds with organic -OH or -COOH groups to form strong gels by cross-linking many polymeric materials and carbohydrates such as cellulose, starch and guar. It reacts similarly as an adhesion promoter on -OH functionalized surfaces. Improves film strength, adhesion promotion, rheology control and corrosion resistance. It cross-links polymers and binders in solvent-borne and water-borne coatings and printing inks. It can also be used for surface modifications of pigments.
