Hydroxy Ethyl Cellulose

Hydroxy Ethyl Cellulose (HEC)


Hydroxyethy Cellulose(HEC) is a non-ionic cellulose ether . It is easily dispersed and dissolved in water to produce solution of high viscosity. HEC is used as a viscosity and rheology modifier, protective colloid, water retention agent, stabilizer and suspending agent, particularly in those applications where a non-ionic material is desired. The product has higher and more uniform degree of substitution, improved the enzyme resistance.

Hydroxyethy Cellulose(HEC) is recommended as thickening agent in water-based paint. It provides excellent thickening efficiency, color development, open time, and superior resistance to biodegradation. It also play a role in the emulsion, dispersion, stability and water retention. The coating has good rheological properties at different shear rates, and has good workability and leveling, not easy to drop, good splash and sag resistance.
