Abstract

L'invention concerne un procédé de préparation de revêtements par enduction de substrats quelconques par des enduits exempts de solvants ou pauvres en solvants, contenant comme liant un mélange à base d'un constituant polyisocyanate et d'un constituant polyol, réagissant pour donner un polyuréthanne. Selon ce procédé, on utilise comme constituant polyol des dispersions de produits de polyaddition de polyisocyanates dans des composés polyhydroxylés organiques. Ces revêtements sont appropriés pour la protection contre la corrosion.
