Organic thickeners for water-borne paints

Abstract

Thickeners are used in paint systems to achieve particular rheological properties such as shear-rate dependent behavior, to control the viscosity at low and high shear rates, sag resistance and application viscosity. This contribution addresses the use and application of thickeners in water-borne paints. Examples of successfully used types of thickeners are the cellulose and PUR-thickeners. Specific compositions, features and benefits of both types are explained in detail.
