Abstract

L'invention vise à développer une substance de revêtement exempte de solvant, résistante à la lumière et aux intempéries et présentant les propriétés indiquées dans l'invention, à base d'un produit de polymérisation durcissable doté de groupes fonctionnels hydroxyle et/ou amino réticulables avec un isocyanate. A cet effet, des nanotubes de carbone sont introduits dans le liant afin d'abaisser la viscosité dans une plage inférieure à 0,1% et d'augmenter la viscosité dans une plage supérieure à 0,1%, un apport d'énergie supérieur à 500 Ws/ml de puissance se traduisant par une homogénéisation.
