Hydroxyethyl Cellulose (HEC)
Hydroxyethyl cellulose (HEC) polymer is a hydroxyethyl ether of cellulose, obtained by treating cellulose with sodium hydroxide and reacting with ethylene oxide. They are available as white free-flowing granular powders that easily dissolve in cold and hot water to give transparent solutions with varying viscosities depending on polymer concentration, type, and temperature.
Aqueous solutions of HEC have excellent characteristics for applications as thickeners，water-retention agents, suspending and dispersing agents, and as protective colloids. HEC polymers are largely used as water-binder and thickening agents in many industrial applications, that is, personal care products, pharmaceutical formulations, building materials, adhesives, etc., and as stabilizers for liquid soaps.
Nature-derived from sustainably sourced cellulose, HEC offers narrow viscosity ranges, consistent viscosity reproducibility, and excellent solution clarities. Hydroxyethyl Cellulose (HEC) hasbeen specifically modified to be applied in a wide range of applications from waterborne architectural coatings, emulsion protective colloids for polymerization.
FEATURES
1.Excellent Thickening Efficiency
HEC is an excellent thickener in water-based paint and coatings. The thickening efficiency is excellent with a wide range of viscosity grades to choose from.Newsanda HEC helps to improve paint abrasion ability and excellent coating ability without flocculation.
2. Water Retention
Adding Newsanda HEC can provide high water retention for water-based coatings. Even if it is applied on a dry substrate or super absorbent substrate, or under the conditions of high temperature and high windspeed, the water-based coating can form a uniform film without cracks and powder falling.
3. Enzyme Resistance
HEC against fungi and resistance to bacterial attack allows its excellent viscosity and stability. and long-term storage.
4. Good Compatibility
HEC is an insoluble cellulose ether with wide compatibility, which can be matched with various additives of polymer lotion and water-borne coatings. They do not undergo chemical reactions, which is beneficial for the stability of water-based coatings during storage.
