    Abstract: The invention relates to a rheology-modifying urethane compound. The compound comprising urethane functions of the invention can be prepared according to a method in several steps which use different compounds comprising isocyanate functions. For the preparation of the urethane compound according to the invention, a monoisocyanate compound, in particular a monoisocyanate compound resulting from the separate condensation of an asymmetric diisocyanate compound with a reactive compound, is reacted with an alkylene glycol compound in the presence of a polyisocyanate compound. The invention also provides coating compositions comprising mineral particles and a urethane compound according to the invention.
