HW-803 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. HW-803 also can act as an adhesion

promoter to oxidized surfaces by a similar mechanism. In addition, HW-

803 can act as a Lewis acid catalyst in processes such as

esterification, transesterification, condensation and addition. Some

commercial applications are as

1. Reaction catalyst: HW-803 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 HW-803 include: Moderate reaction rates; High yield; Easy work-up; Low toxicity; And low catalyst concentration.

2. Oil well fracturing fluids: HW-803 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:HW-803 acts as an effective cross-linking agent of carbohydrate-coated latex particles for highly viscous thixotropic paints.

4. Waterborne paints:HW-803 is an effective cross-linking agent for the pigments and binders in waterborne paints, such as acrylic paints.
