Tyzor® BTP, n-Butyl polytitanate

Tyzor® BTP is a highly reactive organic titanate polymer used in a wide variety of applications. This titanate contains a very high amount of titanium dioxide, making it highly reactive and extremely sensitive to moisture. Tyzor® BTP has a high affinity for reacting with chemical groups such as hydroxyl groups and carboxyl groups. As such, this titanate is an effective cross-linking agent for organic polymers and a strong adhesion promoter for substrates containing these functional groups. As an additive for paints and coatings, Tyzor® BTP serves as a polymer cross-linker while improving adhesion, chemical and abrasion resistance of cured films, and drying time. Tyzor® BTP can also act as a binder, depositing a polymer layer of titanium dioxide through a sol–gel process to help protect against corrosion. This is useful in glass coating applications to improve light reflection and iridescence. As a reaction catalyst, Tyzor® BTP functions as a Lewis acid, reducing byproducts and improving the yield of esterification, addition, and condensation reactions. The Tyzor® BTP titanate has low toxicity and can be used at very low levels.
