Hydroxyethyl Cellulose Ether for Painting, HEC is a highly efficient non-ionic thickener, water-retaining agent and rheological additive, which can be widely used in various water-based latex paints and surface coatings. It has good biological stability and can provide excellent resistance to biological and chemical degradation.
As a non-ionic surfactant, hydroxyethyl cellulose has the following properties in addition to thickening, suspension, bonding, floating, film-forming, dispersing, water-retaining and protective colloid functions:
HEC is soluble in hot or cold water, and does not precipitate at high temperature or boiling, which makes hydroxyethyl cellulose have a wide range of solubility and viscosity characteristics, and non-thermal gelation;
Hydroxyethyl cellulose has a water-retaining capacity twice that of methyl cellulose and has better flow regulation;
HEC has the worst dispersibility compared to the recognized methyl cellulose and hydroxypropyl methyl cellulose, but has the strongest protective colloid ability.
Hydroxyethyl cellulose itself is non-ionic and can coexist with a wide range of other water-soluble polymers, surfactants, and salts. It is an excellent colloidal thickener for solutions containing high-concentration electrolytes.
Hydroxyethyl cellulose (HEC), a white or light yellow, odorless, non-toxic fibrous or powdered solid, is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol), and belongs to the non-ionic soluble cellulose ethers. Due to its good thickening, suspension, dispersion, emulsification, adhesion, film formation, moisture protection and provision of protective colloids, HEC has been widely used in the fields of oil extraction, coatings, construction, medicine and food, textiles, papermaking, and polymer polymerization.
