THE INVENTION CONCERNS A URETHANE TYPE RHEOLOGY MODIFIER WHICH HAS A BRANCHED STRUCTURE DERIVED FROM THE REACTION OF A POLYALKYLENE OXIDE HAVING A MOLECULAR WEIGHT OF BETWEEN 2000 AND 20,000, OF A POLYFUNCTIONAL SUBSTANCE WHICH IS A POLYOL, DIISOCYANATE AND WATER. THIS TYPE OF MODIFIER MAKES IT ALL ABOUT THE VISCOSITY OF THE PRODUCTS IN WHICH IT IS INCORPORATED AND AT THE SAME TIME GIVES THEM OTHER DESIRABLE PROPERTIES, ESPECIALLY IN THE COATING COMPOSITIONS FOR WHICH IT IS PARTICULARLY APPROPRIATE. APPLICATION: MODIFICATIONS OF THE RHEOLOGICAL PROPERTIES OF COMPOSITIONS, ESPECIALLY OF COATING COMPOSITIONS. |
