Polyurethane thickeners

Thickeners are not only used to increase the viscosity of dispersions, but to adjust their rheological profiles, required for certain types of application processes. Our TEGO^® Rheo additives, associative polyurethane thickeners, provide either newtonian or pseudoplastic flow behavior. The achievable thickening properties are excellent even at low pH-values. Moreover the product offers antimisting properties for gravure roll applications.

Our polyurethane thickeners can be used for systems which need to show shear-thinning behaviour as well as for systems that require a stable viscosity independent from shear forces, e.g. thick layer applications.
