Abstract:
(EN) Curable aminoplast acrylic polyol composition containing, calculated as solids on all the solids of the composition, (a) 50 to 85% by weight of at least one type of an acrylic polyol having a glass transition temperature Tg of from 15 to <50°C, an equivalent weight of hydroxyl groups on solids of from 330 to 420, a hydroxyl number on solids of from 120 to 180 mg KOH/g, and a number average of the molecular weight (Mn) of 1,000 to 3,000 Dalton, and (b) 15 to 50% by weight of an alkylated amino formaldehyde resin having a formaldehyde content in accordance with DIN EN ISO 1 1402 4.3 of less than 0.10%, and - the amino compound is melamine, guanamine, benzoguanamine, urea, toluenesulfonamide and glycoluril, and the alkylated amino formaldehyde resin containing at least one type of alkyl groups having 1 to 12 carbon atoms, and (c) 0.5 to 5.0% by weight of at least one type of an acidic catalyst; a process of its preparation and methods of its use.
(FR) L'invention concerne une composition de polyol acrylique à aminoplaste durcissable contenant, calculé sur la base du poids total des matières solides de la composition : a) 50 à 85% en poids d'au moins un type de polyol acrylique ayant une température de transition vitreuse Tg de 15 à < 50°C, un poids équivalent de groupes hydroxyle sur des matières solides de 330 à 420 ; et un indice d'hydroxyle sur des matières solides de 120 à 180 mg KOH/g ; et un nombre moyen du poids moléculaire (Mn) de 1000 à 3000 Dalon, et b) de 15 à 50 % en poids d'une résine amino-formaldéhyde alkylée dont la teneur en formaldéhyde est inférieure à 0,10 % selon la norme DIN EN ISO 1402 4.3, et le composé amino est mélamine, guanamine, benzoguanamine, urée, toluènesulfonamide et glycolurile, et la résine aminoformaldéhyde alkylée contient au moins un type de groupes alkyle ayant 1 à 12 atomes de carbone ; et c) de 0,5 à 5,0 % en poids d'au moins un type de catalyseur acide. L'invention concerne un procédé de préparation et des procédés d'utilisation de la composition.
