Tyzor® TPT is an alkoxy titanate with a high level of reactivity. It is most commonly used as a Lewis acid and a Ziegler–Natta catalyst.
Tyzor® TPT is a 100% active tetra-isopropyl titanate in liquid form. This Tyzor® titanate is typically used as a metal catalyst in producing polyolefins and polycarbonate. It improves the yield of olefin polymerization, esterification, condensation, and addition reactions while eliminating unwanted byproducts. Compared to other Tyzor® titanates, Tyzor® TPT is highly moisture sensitive and will decompose when exposed to water.
Tyzor® TPT is useful as a replacement for tin, organostannanes, and sulfuric acid in esterification reactions when toxicity reduction is desired. Tyzor® TPT is even more efficient than sulfuric acid in esterification reactions. When added to solvent-based paints, Tyzor® TPT will cross-link hydroxyl and carboxyl functional polymers to increase chemical and heat resistance. Like many other Tyzor® grades, it can also be used to coat metal and glass surfaces with a thin polymeric film of titanium dioxide. This can promote adhesion, improve surface hardness, increase light reflection, and add coloring effects.
