CELLOSIZE™ QP-10000H Hydroxyethylcellulose is a medium molecular weight water soluble polymer that is commonly used as a thickener, binder, and film former in various applications. It is surface treated to delay hydration.
CELLOSIZE™ QP-10000H is a surface treated hydroxyethyl cellulose polymer that is used in a variety of applications as a rheology modifier, thickener, binder, and film former. It has been surface treated to delay hydration. The delayed hydration allows for the polymer to be completely dispersed in water prior to hydration in order to avoid the formation of lumps and gel. Once dispersed hydration can be started by increasing the pH or temperature. CELLOSIZE™ QP-10000H Hydroxyethylcellulose will produce a solution with a viscosity of 6000-7000 when added to water at 2%. The molecular weight of the polymer is tightly controlled and allows for better consistency when compared to other hydrocolloids like guar and xantham gum.

Low viscosity of water based formulations
Difficulties with hydration of hydrocolloid thickeners
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.
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.
