Tyzor® AA-75 is a solvent-based titanium acetylacetonate complex. It is used as a cross-linker, a curing agent, an adhesion promoter, and a titanium source for inks and coatings.
In terms of chemical composition, Tyzor® AA-75 is a titanium acetylacetonate complex belonging to the organic chelate family of Tyzor® titanates. It is similar to the Tyzor® AA titanate but offered at 75% solids. Tyzor® AA-75 is utilized in solvent-based ink and coating formulations for its excellent adhesion-promoting, cross-linking, and curative properties. It will cross-link hydroxyl and carboxyl groups to improve drying speed, solvent resistance, heat stability, and hardness. Similarly, it will form chemical bonds with substrates containing hydroxyl functional groups to improve adhesion. The Tyzor® AA-75 titanate can also be used to form TiO2 films or as a catalyst to improve esterification, condensation, and addition reactions by reducing byproducts and increasing yield.
