Overview
Tyzor® 9000 is a 100% active moisture-sensitive alkoxy titanate used across various industries. It is commonly used to cross-link polymers with hydroxyl or carboxyl functionality. In coating applications, this increases the hardness, heat resistance, and chemical resistance of cured films. Tyzor® 9000 is also used as a binder to form polymeric titanium dioxide films on surfaces. As a catalyst, Tyzor® 9000 acts as a Lewis acid and is well suited for esterification, condensation, and addition reactions. It eliminates byproducts, increases yield, and is much lower in toxicity than other metal catalysts, such as tin. This makes Tyzor® 9000 a good replacement for organostannanes and other hazardous metal catalysts used in industrial phthalic acid and DEG polyol synthesis.
