Product Description HydroxyEthy Cellulose (HEC for short) is a non-ionic soluble cellulose ether, both soluble in cold and hot water, with thickening, suspension, adhesion, emulsification, film-formation, water retention, protective colloids and other properties, widely used in coatings, cosmetics, detergent, toothpaste,oil drilling and other industries. Dissolve Hydroxyethy Cellulose in water Retarded Hydroxyethy Cellulose can be directly added into paint formulation, will form homogeneous, glazed solution. Period from powder wetted till dissolution completed call hydration time. During this process, solution build up thickening ability. Temperature and PH has effect on hydration time. Increase PH to 8.0-10.0, will shorten the time 40-60%; temperature increase will shorten this time as well. Normally, we suggest to add Hydroxyethy Cellulose at room temperature and neutural situation, hydration time is around 25 minutes. HEC is an non-ionic water-soluble polymer, it is white to slight yellow, odorless and tasteless powdered solid. It is mainly used as viscosifier and fluid loss agent in oildrilling.
