Technical Data

CELLOSIZE QP 300 hydroxyethyl cellulose

Product Description

CELLOSIZE™ QP 300 hydroxyethyl cellulose (HEC)

is a medium-low molecular weight cellulosic polymer

used as both a protective colloid and a latex paint

thickener. In the emulsion polymerization of vinyl and

acrylic monomers to produce latexes for architectural

coatings, the typical use level of CELLOSIZE QP 300

HEC in latex synthesis is 2% by weight (based on total

monomers) in vinyl and vinyl-acrylic latex formulations

(usually less in all-acrylic formulations). The nearly

Newtonian behavior of aqueous solutions of

CELLOSIZE QP 300 HEC make it an ideal thickener

in premium quality latex paints, giving paints with good

flow and leveling characteristics. The typical use levels

of CELLOSIZEQP 300 HEC in latex paints are

between 5 and 8 pounds per 100 gallons. CELLOSIZE

QP 300 HEC is also used in cement as a fluid loss additive.
