Hydroxyethyl cellulose (HEC) is a white or light yellow, tasteless, non-toxic, fibrous or powdered solid prepared by etherification of alkaline cellulose and ethylene oxide (or chloroethanol). It is a nonionic soluble cellulose ether. Due to its good properties of thickening, suspension, dispersion, emulsification, adhesion, film formation, water protection and colloidal protection, HEC has been widely used in the fields of petroleum exploitation, coatings, construction, pharmaceutical food, textile, papermaking and polymer polymerization
Hydroxyethyl cellulose HEC is a natural polymer cellulose as raw material, is a non-ionic cellulose ether produced through a series of chemical processing. It is an odorless, tasteless and non-toxic white powder. It can be dissolved in water and has the characteristics of thickening, adhesion, dispersion, film formation and so on. It has strong water retention performance. It can be thickened and bonded in cement mortar. It can also improve fluidity and workability when added in mortar, prolong the evaporation time of water, and avoid cracks in the initial stage of concrete.
Hydroxyethyl cellulose HEC is widely used in other building materials.
