TCA-TE Titanium diisopropoxide bis (triethanolamine) Tyzor TE (CAS No. 36673-16-2) CAS NO.36673-16-2

TiLink^TM titanate TCA-TE is a triethanolamine titanium complex with 80% active ingredient in alcohol solvent. It is a clear, light yellow organic liquid and suitable in aqueous coatings and adhesives.

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.

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.

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.

Thixotropic paints

TCA-TE acts as an effective cross-linking agent of carbohydrate-coated latex particles for highly viscous thixotropic paints.

Waterborne paints

TCA-TE is an effective cross-linking agent for the pigments and binders in waterborne paints, such as acrylic paints.

Applications Performance

TCA-TE reacts with water by hydrolysis to form a reactive hydroxy titanium chelate. The chelate is stable in water fextended periods. Theiginal hydrated chelate can form complexes withganic -OH -COOH groups. When reacted in this way with multifunctional polymers such as carbohydrates (e. G., cellulose, starch 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 addition. Some commercial applications are as

1. Reaction catalyst: TCA-TE can act as a Lewis acid catalyst festerification, transesterification, condensation addition reactions.
