CELLOSIZE EP 09 is a very low molecular weight hydroxyethyl cellulose product designed for use in emulsion polymerization. CELLOSIZE EP 09 promotes emulsion stability and improves latex rheology when grafted on emulsion polymer particles. Its low viscosity and absence of gels reduces the risk of possible grit formation in polymerization processes. CELLOSIZE EP 09 also finds use in applications requiring good dispersion properties like protective films and self-leveling compounds due to its surface treatment ensuring fast dissolution in water. The unique substitution pattern of CELLOSIZE EP 09 enhances stability in ambient, neutral water systems.
