HEC in Paint & Coatings
As a non-ionic surfactant, hydroxyethyl cellulose - HEC has the following properties in addition to thickening, suspending, bonding, emulsifying, film-forming, dispersing, water-retaining and providing protection:
1. HEC is soluble in hot or cold water, and does not precipitate under high temperature or boiling, so that it has a wide range of solubility and viscosity characteristics, that is, non-thermal gelation;
2. It is non-ionic and can coexist with a wide range of other water-soluble polymers, surfactants, and salts. It is an excellent colloidal thickener containing high-concentration electrolyte solutions;
3. Water retention capacity is twice higher than that of methyl cellulose, and it has better flow regulation;
4. The product has stable viscosity, anti-mildew, and makes the coating have a better can-opening effect, and has a better leveling performance during construction;
Application : water emulsion paint:
As a protective colloid, HEC can be used for vinyl acetate emulsion polymerization to improve the stability of the polymerization system in a wide pH range. In the manufacture of finished products, additives such as pigments and fillers are used to uniformly disperse, stabilize and provide thickening. It can also be used as a dispersant for styrene, acrylic, propylene and other suspension polymers. Used in latex paint, it can significantly improve the thickening and leveling performance.
