Abstract
The mixture of the invention comprises at least one cycloaliphatic polyisocyanate and at least one solvent comprising an ester function and an ether function. An aqueous emulsion can be obtained from this mixture which also comprises a compound bearing a function with a mobile hydrogen, selected from primary or secondary hydroxyl functions, phenol functions, primary and/or secondary amino functions, carboxylic functions and a thiol function or a compound containing precursor functions capable of freeing hydroxyl functions. The emulsion can be used for the manufacture of coatings on a substrate of cement, of wood or especially of leather, and also for the manufacture of adhesives.
