Applications and Performance
TCA-TE reacts with water by hydrolysis to form a reactive hydroxy titanium chelate. The chelate is stable in water for extended periods. The original or hydrated chelate can form complexes with organic -OH or -COOH groups. When reacted in this way with multifunctional polymers such as carbohydrates (e. G., cellulose, starch and guar gum), strong gels may be formed by cross-linking. TCA-TE also can act as an adhesion promoter to oxidized surfaces by a similar mechanism.
In addition, TCA-TE can act as a Lewis acid catalyst in processes such as esterification, transesterification, condensation and addition. Some commercial applications are as
1. Reaction catalyst: TCA-TE can act as a Lewis acid catalyst for esterification, transesterification, condensation and addition reactions. It is especially well suited to direct esterification processes due to its excellent compatibility with the water by-product. The benefits of using TCA-TE include: Moderate reaction rates; High yield; Easy work-up; Low toxicity; And low catalyst concentration.
2. Oil well fracturing fluids: TCA-TE is an effective cross-linking agent for dispersions of guar and its derivatives to form high-viscosity aqueous gels used in oil well fracturing applications.
3. Thixotropic paints: TCA-TE acts as an effective cross-linking agent of carbohydrate-coated latex particles for highly viscous thixotropic paints.
4. Waterborne paints: TCA-TE is an effective cross-linking agent for the pigments and binders in waterborne paints, such as acrylic paints.
Packing
The regular packing of TiLink TCA-TE is 25 liters plastic pail and 200 liters steel drum.
