Cellosize ER 52M Hydroxyethyl cellulose Dow Chemical Rheology Modifier/ Thickener >> Cellulosic, non associative >> Hydroxyethyl cellulose (HEC) Coatings >> Waterborne Architectural / Decorative General Industrial /Maintenance Soluble in hot or cold water CELLOSIZE™ ER 52M hydroxyethyl cellulose (HEC) is a high molecular weight, enzyme-resistant cellulosic polymer. It is used extensively as a thickener in latex paints where paint formulators want an HEC polymer with high thickening efficiency. CELLOSIZE ER 52M HEC is a popular choice with many paint formulators, and typical use levels in latex paints are between 4 and 6 pounds per 100 gallons. Aqueous solutions of CELLOSIZE ER 52M HEC exhibit a high degree of pseudoplasticity (shear thinning), and are rheologically similar to CELLOSIZE QP 52000H HEC. Like all CELLOSIZE ER HEC products, CELLOSIZE ER 52M HEC contains about 1% fumed silica as a flow-aid. paints and coatings High molecular weight, enzyme-resistant cellulosic polymer.
