TYZOR® TPT 20B

REACTION CATALYST

Tyzor® TPT-20B is an effective Lewis acid catalyst for esterification, transesterification, condensation, and addition reactions. It is also useful as a Ziegler-Natta catalyst for polymerizations. Typical reaction products include (meth)acrylic esters, polyester, plasticizers, various esters, and polyurethanes. Tyzor® TPT-20B can be stored and used at relatively low temperatures. It is low in toxicity, eliminates by-products, and increases yields. It is easy to work with and can be used at low concentrations.

COATINGS

Glass, metals, fillers, and pigments can be treated with Tyzor® TPT-20B to increase surface hardness, promote adhesion, and improve resistance to heat, chemicals, corrosion, and scratches. It can also be used to add coloring effects or enhance light reflection or iridescence.

PAINT ADDITIVES

Tyzor® TPT-20B can serve as a binder and adhesion promoter, and it cross-links functional polymers or other binders in paints.

TiO₂ PIGMENTS AND FILMS

Micro- or nano-scale TiO₂ pigments can be formed with Tyzor® TPT-20B. It can also be used to create polymeric TiO₂ surface films via pyrolytic or hydrolytic processes. In sol-gel applications with other metal alkoxides, total or partial hydrolysis of Tyzor® TPT-20B yields metal oxide systems for binders or coatings.

Tyzor® TPT-20B is usually formulated with other ingredients in catalysis, cross-linking, or paint applications, and it is typically added last to prevent undesired pre-reactions with water or other system components. For adhesion promotion or surface modification, it is often applied as a primer from a dilute solution.
