n-propyl titante
Description
TNPT, tetra-n-propyl titanate, is a highly reactive organic alkoxy titanate with 100% active content. It is a clear, colorless-to-yellowish liquid that is very sensitive to moisture. NPT acts as a Lewis acid catalyst in processes such as esterification, transesterification, condensation and addition. It also can be used to promote adhesion and cross-linking of polymers, or to form polymeric titanium dioxide layers used as binders or coatings.
Applications
▲ REACTION CATALYSTS: NPT is used in Ziegler-Natta catalysts for olefin polymerization. It may also be used as a catalyst for esterification, transesterification, condensation and addition reactions. Typical reaction products include polyolefins, (meth)acrylic esters, polyester, plasticizer, various esters and polyurethanes. Benefits include elimination of by-products, increased yield, easy work-up, low catalyst concentration and low toxicity.
▲ COATINGS: Glass, metals, fillers and pigments can be treated with NPT to increase surface hardness, promote adhesion, improve resistance to heat, chemicals, corrosion and scratches, add iridescence or enhance light reflection.
▲ PAINT ADDITIVES: NPT is useful as a binder and also can be used as an additive or cross-linker for –OH or –COOH functional polymers and other binders in paints.
▲ TiO2 pigments and films: Micro- or nano-scale TiO2 pigments can be formed from NPT. It can also be used to create a polymeric TiO2 film on surfaces via pyrolytic or hydrolytic processes.
