Cellosize™ EP-300 Hydroxyethylcellulose (HEC) is a water soluble polymer with emulsion polimerization that can thicken, suspend, bind, emulsify, form films, stabilize, disperse and retain water. It has a viscosity range of 250-400, a 2% solution concentration with a spindle number 2 and 60 RPM
Cellosize™ EP-300 Hydroxyethylcellulose (HEC) is a nonionic, water-soluble polymer that can thicken, suspend, bind, emulsify, form films, stabilize, disperse, retain water, and provide protective colloid action. It is a free-flowing powder that readily dissolves in hot or cold water without excessive mixing or heating.

Settling of latex emulsions during storage
Paint thickening – low-foaming and efficient stabilizer for water-based paints.
Oil production – build viscosity in drilling, work-over, and completion fluids for oil recovery operations.
Latex polymerization – create monomer emulsions, stabilize growing polymer particles during polymerization, and impart freeze/thaw and shear stability to the latex product.
Agriculture – suspend solid pesticides in water-based sprays, help bind the pesticide to foliage, and help thicken spray emulsions to reduce spray drift. HEC can also be used as a seed coating.
Construction – gypsum, cement, lime, and organic plasters, tile adhesives, and
mortars.
Cosmetics and detergents – thickener, film-former, binder, stabilizer, and dispersant in shampoos, creams, neutralizers, and lotions.
Paper and inks – gloss and ink hold-out sizing. Also contributes to improved
grease resistance and improved water retention of coating colors.
Textile sizes, coatings, binders, and adhesives and dyeing aids – warp sizing and finishes that can be removed by laundering, as well as an adhesive thickener and binder to control strike-through and improve print definition.
Household products – thickener, stabilizer, and binder in liquid detergents and
cleaners, fabric softeners, polishes, and air fresheners.
