METHOD FOR PROVIDING A SUBSTRATE WITH A COATING WITH HIGH IMPACT STRENGTH PROPERTIES

摘要

The invention concerns a method for providing a substrate with a coating with high impact strength properties, characterised in that it consists in applying on said substrate an aqueous masked (poly)isocyanate emulsion having a droplet average size less than 10 mu m, advantageously less than 5 mu m, preferably less than 1 mu m, and in reacting it with a polyol in conditions leading to crosslinking of the (poly)isocyanate with the polyol.
