Tyzor® TnBT, tetra-n-butyl titanate

Tyzor® TnBT is a highly reactive alkoxy titanate that is commonly used as a Lewis acid catalyst in esterification, condensation, and addition reactions.
Product Overview
Tyzor® TnBT is a 100% active, tetra-n-butyl titanate liquid. It is extremely sensitive to moisture and will decompose rapidly in water. It's most common use is as a metal catalyst in the production of polyester polyols, polybutylene terephthalate, and polytrimethylene terephthalate where it helps improve yield and eliminates unwanted by-products. Tyzor® TnBT is also used in olefin polymerization as a Ziegler-Natta catalyst. As metal catalyst, Tyzor® TnBT serves as a non-toxic replacement for organostannanes, tin, and other toxic metals used in organic synthesis. Tyzor® TnBT can be used to treat glass and metal surfaces to promote adhesion, improve scratch resistance, and improve light reflection. Thin polymeric films of titanium dioxide can be formed on surfaces to increase iridescence and add coloring effects. Tyzor® TnBT can also be added to paints and coatings to cross link polymers that have carboxyl and hydroxyl functionality.
