Abstract

L'invention concerne un mélange de substances appropriées en tant que vernis en poudre ou en tant que liants pour vernis en poudre, solides et pulvérisables en dessous de 40 degrés C, liquides au-dessus de 150 degrés C, constitué essentiellement par : a. Un composant isocyanate présentant des groupes isocyanate bloqués; b. Un composant polyhydroxylé et, éventuellement, c. Les additifs et les agents auxiliaires classiques. Selon l'invention, on utilise comme posant a un polyisocyanate à groupes isocyanurate, présentant des groupes isocyanate bloqués par des lactames. Utilisations en tant que vernis en poudre ou en tant que liants pour vernis en poudre pour revêtir des substrats résistant à la chaleur quelconques, selon les techniques connues de revêtement, appropriées pour le traitement de vernis en poudre.
