Emulsion Polymerization

Reliable protective colloids with consistent performance

Synthetic latices, used e.g. as binders in paints and adhesives, can be characterized as aqueous dispersions of polymer particles produced by a chemical process known as emulsion polymerization. In this process, monomers are converted into polymers in an aqueous emulsion system in the presence of emulsion stabilizers and catalyzed by water-soluble radical initiators.

Our Solutions

CELLOSIZE™ hydroxyethyl cellulose is used as part of the latex stabilizer system where it acts as a protective colloid. CELLOSIZE™ contributes to both stability and rheology of the system.

CELLOSIZE™ is available in a wide range of grades, allowing the selection of the appropriate protective colloid for any given application requirement of stability and rheology. The narrow specification limits of the various CELLOSIZE™ grades offer a highly reproducible and reliable product needed for the production of emulsion polymers.

CELLOSIZE™

CELLOSIZE™

Benefits/Property
Stabilizer and rheology modifier; Narrow specification limits

Applications
Protective colloid in the emulsion polymerization of vinyl homopolymers and vinyl copolymers, including vinylacrylics but also in the polymerization of acrylics.

Your Applications

CELLOSIZE™ hydroxyethyl cellulose function as a protective colloid used as part of the latex stabilizer system. The broad range of available CELLOSIZE™ grades and their narrow specifications allow the selection of the ideal stabilizer for a given system.
