Title (EN) POLYHEDRAL OLIGOMERIC STANNASILSESQUIOXANES AS CATALYST FOR POLYURETHANE CURING
(FR) STANNASILSESQUIOXANES OLIGOMÉRIQUES POLYÉDRIQUES EN TANT QUE CATALYSEUR POUR LE DURCISSEMENT DE POLYURÉTHANES
Abstract: front page image
(EN)The invention relates to a curable composition comprising the following components: (A) at least one isocyanate, (B) at least one binder, and (C) at least one polyhedral oligomeric silsesquioxane, with the number of cages z per molecule being 2 or 3 and the number of tin atoms per molecule being at least one. Furthermore, the invention refers to a kit of parts comprising as components A), B), and C); to the use of the polyhedral oligomeric silsesquioxanes in coatings, lacquers, paintings, films and polymer compositions; to coatings obtainable by curing of these compositions; and to the use of polyhedral oligomeric silsesquioxanes containing at least one metal atom, in particular polyhedral oligomeric stannasilsesquioxane to increase the scratch resistance of coatings.
(FR)L'invention concerne une composition durcissable comprenant les composants suivants : (A) au moins un isocyanate, (B) au moins un liant, et (C) au moins un silsesquioxane oligomérique polyédrique dont le nombre de cages z par molécule est de 2 ou 3 et le nombre d'atomes d'étain par molécule est d'au moins un. En outre, l'invention concerne un nécessaire d'éléments comprenant comme composants A), B) et C) ; l'utilisation de silsesquioxanes oligomériques polyédriques dans des revêtements, des laques, des peintures, des films et des compositions de polymère, des revêtements pouvant être obtenus par durcissement de ces compositions, et l'utilisation de silsesquioxanes oligomériques polyédriques contenant au moins un atome de métal, en particulier un stannasilsesquioxane oligomérique polyédrique, afin d'augmenter la résistance aux rayures des revêtements.
