The products of this series have good peoperties of thickening, anti-settling, thixotropy and emulsion stability and gel dispersability. The productsare bery easy to be dispersed in solutions of low, midddle and high polarities to form thixotropic gel. The products are widely applicable in paint, ink, high-temperature lubicants fine coatings, sealing grease, glass fibers, resin, oil well drilling liquid and cosmetic products.
