Patent

CA 2289510

The invention relates to a coating agent containing a) one or more polyester resins (A); b) one or more polyacrylate resins (B); c) one or more di- and/or polyiscyanates (C) with free or blocked isocyanate groups; d) one or more light stabilizers (L1) based on a UV absorber; e) one or more light stabilizers (L2) based on sterically hindered amines; and f) one or more organic solvents (D). The coating agent is characterized in that 1) the polyester (A) has a hydroxyl number of 80-200 mg KOH/g and an acid number < 10 mgKOH/g; 2) the plyacrylate resin (B) has a hydroxyl number of 80-200 mgKOH/g and an acid number < 20 mgKOH/g; and 3) the light stabilizer (L2) base on sterically hindered amines is functionalized by aminoether.

L'invention a pour objet un agent de revêtement renfermant a) une ou plusieurs résines polyester (A), b) une ou plusieurs résines polyacrylate (B), c) un ou plusieurs di- ou polyisocyanates (C) à groupes isocyanates libres ou protégés, d) un ou plusieurs agents de stabilité à la lumière (L1) à base d'absorbeur UV, e) un ou plusieurs agents de stabilité à la lumière (L2) à base d'amines à empêchement stérique et, f) un ou plusieurs solvants organiques (D), caractérisé en ce que 1) le polyester (A) présente un indice OH de 80 à 200 mg KOH/g et un indice d'acide < 10 mg KOH/g, 2) la résine polyacrylate (B) présente un indice OH de 80 à 200 mg KOH/g et un indice d'acide < 20 mg KOH/g, et 3) l'agent de stabilité à la lumière (L2) à base d'amines à empêchement stérique est fonctionnalisé par un aminoéther.
