October 12, 2011
Cornelius offers Rheolate 299, a highly efficient and strongly shearing thinning associative thickener. It is a polyether polyurethane thickener for aqueous industrial and decorative, pigmented and clear coating systems. Rheolate 299 is a highly efficient, 25% active, polyether polyurethane associative viscosity builder for the low- to mid-shear rate range. It provides strongly shear-thinning flow behavior, which makes it ideal for spray applications including, sprayed latex emulsions, dispersions, water reducible clear-coats and high gloss pigmented systems. Rheolate 299 is a pourable liquid and can be incorporated at any point in the formulation of most systems. Liquid associative thickeners are usually post-added for convenience. Rheolate 299 efficiently provides strongly shear thinning flow behavior to both pigmented and clear waterborne coating systems. This results in excellent application properties, sag resistance and storage stability, according to the company.
