Title (EN) COATING FILMS WITH REDUCED YELLOWING
(FR) FILMS DE REVÊTEMENT À JAUNISSEMENT RÉDUIT
Abstract:
(EN) The invention relates to a coating composition containing a combination C of a hydroxy- functional cationic resin R based on reaction products of multifunctional epoxides E having, on average, two or more epoxide groups per molecule, and aliphatic amines A having primary and/or secondary amino groups, and a crosslinker which is a blocked isocyanate IB prepared from a multifunctional isocyanate I and a hydroxy-functional blocking agent B, which blocked isocyanate IB has an amount of substance-fraction of from 5 % to 30 % of allophanate structures in the sum of urethane and allophanate structures, and wherein the amines A do not comprise more than a specific amount of 0.1 mol/kg of amines A3 having tertiary amino groups, to a process for its preparation, and to a method of use thereof.
(FR) L'invention concerne une composition de revêtement contenant une combinaison C d'une résine cationique R à fonction hydroxy se basant sur des produits de réaction d'époxydes multifonctionnels E ayant, en moyenne, deux groupes époxydes ou plus par molécule, et des amines aliphatiques A ayant des groupes amino primaires et/ou secondaires, et un agent de réticulation qui est un isocyanate bloqué IB préparé à partir d'un isocyanate multifonctionnel I et d'un agent bloquant à hydroxy fonctionnel B, ledit isocyanate bloqué IB ayant une quantité de fraction de substance de 5 % à 30 % de structures allophanate dans la somme des structures uréthane et allophanate, et les amines A ne comprenant pas plus d'une quantité spécifique de 0,1 mol/kg d'amines A3 ayant des groupes amino tertiaires ; un procédé pour sa préparation ; et un procédé d'utilisation de celle-ci.
