Poly(titanium butoxide)

Details:

DESCRIPTION: PBT is a polymeric butyl titanate with 100 % active content. PBT is a clear yellowish organic liquid which is very sensitive to moisture. PBT has a very high TiO2 content and releases a lower amount of VOC’s compared with many other titanate products.

FUNCTIONALITY:

• PBT acts as a Lewis Acid catalyst in processes such as esterification, transesterification, condensation, addition, etc.
• PBT can effect adhesion promotion and crosslinking of polymers, or form polymeric titanium dioxide layers used as binders or coatings.

APPLICATIONS:

• Reaction Catalyst: Reaction Catalyst Coatings Paint Additive Binder TiO2 Pigment and Films PBT is an effective catalyst for esterification, transesterification, condensation, and addition reactions. Benefits are moderate reaction rates, high yield, easy work-up, low toxicity, and low catalyst concentration.
• Coating: Glass, metals, fillers, pigments, and plastic can be treated with PBT to give increased surface hardness, adhesion promotion, coloring effects, heat and light reflection, iridescence, and corrosion resistance, and scratch resistance.
• Paint Additive: PBT can be used as an additive in paints to crosslink –OH and -COOH functional polymers or binders, promote adhesion, or act as a binder itself.
• Binder: PBT can act as inorganic binder alone or in combination with other metal oxide for mineral filled systems providing high temperature resistance.

TiO₂ Pigment and Films: Micro- or nano-scale TiO₂ pigments can be formed from PBT. It can also be used to create a polymeric TiO2 film on surfaces via pyrolytic or hydrolytic (e.g. sol-gel) processes
