A non-ionic urethane rheology modifier based on solvent-free* technology offering improved efficiency without sacrificing key performance properties. It offers a Newtonian rheology profile for excellent flow and leveling with high film-build while maintaining good sag resistance, combined with excellent water and alkali resistance. This offers a distinct rheology profile and can replace traditional combinations of medium- and high-shear urethane rheology modifiers. Depending on the formulation the rheology modifier dosage can be reduced up to 40%. It can be used either alone or in combination with other thickeners, including PRIMAL™ RM-5000.
