Tyzor® GBA is a freeze-resistant titanium acetylacetonate. It is commonly used in inks and coatings to improve drying, durability, and adhesion.
Tyzor® GBA titanate is a titanium acetylacetonate compound that functions as an organic chelate. Unlike other Tyzor® titanates, Tyzor® GBA contains a mixture of alcohols to resist freezing in low-temperature storage conditions.
Tyzor® GBA promotes cross-linking and adhesion with various compounds containing hydroxyl and carboxyl groups. This makes it useful as a curative in a variety of ink and coating applications. When used as a cross-linker, this titanate is preferred to add to the polymer or binder. Compared to other Tyzor® organic titanates, Tyzor® GBA is moderately reactive with water and will undergo hydrolysis to form hydrous titanium dioxide. Therefore, when used as an adhesion-promoting additive, it should be added as the last ingredient to prevent hydrolysis or unwanted reactions. Tyzor® GBA can also form polymeric titanium dioxide films on metal or glass surfaces to provide protective properties.
It also functions as a nontoxic Lewis acid catalyst in esterification, transesterification, condensation, and addition reactions, making it useful in manufacturing polymers such as polyesters and polyurethanes. Here, Tyzor® GBA organic titanate helps eliminate reaction byproducts, increases yield, and provides easy workup.
