CELLOSIZE QP-300

产品描述

CELLOSIZETM QP 300 羟乙基纤维素(HEC)是一种中低分子量的纤维素聚合物,用于胶体保护剂和涂料增稠剂. 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 CELLOSIZE QP 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
