Applications and Performance
TCA-LA is a water based titanium chelate that is stable in water at pH 7 even in the presence of possible reactants. TCA-LA is an excellent choice for use in aqueous systems. It is stable so long as the pH is maintained around 7~8. TCA-LA can act as catalyst in applications such as esterification, transesterification, condensation.
TCA-LA can effect crosslinking of -OH functional polymers, adhesion promotion, and formation of polymeric titanium dioxide as binder or coating. Some regular commercial applications are as below for your information:
1. Catalyst:
TCA-LA is an effective 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 byproduct. Effects are moderate reaction rates, high yield, easy work-up, low toxicity, and low catalyst concentration.
2. Oil well fracturing fluids:
TCA-LA is an effective crosslinker for dispersions of guar and its derivatives to form high viscosity aqueous gels used in oil well fracturing applications.
3. Paints and coatings:
TCA-LA can crosslink binders in -OH functional water borne paints. Heating can be used to form a polymeric titanium dioxide layer used as binder or coating on various substrates to effect e. G. Adhesion, increased surface hardness, heat and light reflection, corrosion resistance, and scratch resistance.
Packing
The regular packing of this product is 25 liters plastic pail and 200 liters steel drum.
