Associative Thickener-HEUR

VOC-free associative thickener based on HEUR technology for aqueous architectural coatings. Highly efficient Newtonian behavior.


OPTIFLO L1400 is an aqueous solution of a hydrophobically modified nonionic polymer commonly called an associative thickener. The use of OPTIFLO L1400 will increase film build by efficiently generating high shear viscosity with very little impact on low shear viscosity.

Recommended Use

OPTIFLO L1400 is designed to thicken dispersion (latex) paints. It may be used with acrylic, styrene/acrylic, and vinylacetate copolymer latexes.

Recommended Levels

OPTIFLO L1400 is typically used at 8.0-35.0 wet pounds per 100 gallons of the final formula, but the amount required will depend upon the specific formulation.
