HEC For Interior Water Based Coatings

1. For water emulsion paint As a protective colloid, HEC can be used in the emulsion polymerization of vinyl acetate to improve the stability of the polymerization system in a wide pH range. Additives such as pigments and fillers are used in the manufacture of finished products to evenly disperse, stabilize and provide thickening effect. It can also be used as dispersant for benzene, acrylate, acrylonitrile and other floating polymers.

2. Oil drilling HEC is used as a thickener among all kinds of mud required for drilling, well setting, cementing and fracturing operations to ensure good fluidity and stability of the mud. The mud carrying capacity is improved during drilling, and a large amount of water is prevented from entering the reservoir from the mud, thus stabilizing the production capacity of the reservoir.

3. For building materials construction and building materials Because of its strong water retaining capacity, HEC is an effective thickener and binder for cement slurry and mortar. Adding HEC into mortar can improve fluidity and construction performance, prolong water evaporation time.
