Tyzor® LA, titanium chelate

Tyzor® LA is a hydrolytically stable titanium chelate identified under CAS number 65104-06-5. While most Tyzor® titanates decompose and undergo hydrolysis, this titanate remains stable in water as long as the pH remains between 7 and 8. Therefore, Tyzor® LA is well suited as a catalyst in direct esterification reactions of carboxylic acid compounds because of its compatibility with water, which may be present in raw materials. Due to its lower titanium content, this titanate offers moderate reaction rates but produces a high yield and provides increased safety through its nontoxicity. When used as a catalyst, Tyzor® should be added as the last ingredient of the reaction components to prevent unwanted chemical prereactions.

Tyzor® LA is used in water-based coatings and inks to cross-link binders and pigments and improve the cohesive strength and toughness of coating formulations. It is also used to promote the adhesion of water-based coatings and inks.

Tyzor® LA is also excellent for crosslinking water-based dispersions of guar to produce high-viscosity oil well fracturing fluid. Surfaces like metal and glass can also be treated with Tyzor® LA to improve the adhesion of coatings, inks, and adhesives.
