Product Overview

CELLOSIZE™ EP-09 is a low molecular weight, water soluble. non-ionic, hydroxyethyl cellulose emulsion stabilizer.  The low molecular weight and moderate hydration time make it an excellent steric stabilizer for water-based latex systems.  CELLOSIZE™ EP-09 is grafted onto a forming polymer in emulsion polymerization and will bind water to form a protective colloid around the latex particle.  This bound water acts as a transitional layer and provides stability to the colloidal system.  CELLOSIZE™ EP-09 is surface treated to delay the hydration of the polymer when added to water.  Hydration can be sped up by increasing the pH or temperature once the polymer is completely dispersed.  CELLOSIZE EP-09 will yield solutions with a viscosity of 90-160 cP when added to water at 5 wt%.
