Hydrophobically modified ethylene oxide urethane (HEUR) high-shear rheology modifier for waterbased coatings. Solvent-free, non-ionic, urethane associative thickener offering very versatile means of formulating paints with an optimal film build and high shear viscosity. It is specifically designed for applications where a low odour or low VOC is required and specific environmental requirements are needed. However, Suggested in a wide range of other paints. It can be used either alone or in combination with thickeners effective in the low shear range to reach the desired balance of flow and sag resistance.
