Title (EN) MULTI-LAYER COATING SYSTEM INCLUDING A HYDROXYL MODIFIED POLYURETHANE DISPERSION BINDER
(FR) SYSTEME DE REVETEMENT MULTICOUCHE COMPRENANT UN LIANT SOUS FORME DE DISPERSION DE POLYURETHANE A MODIFICATION HYDROXYLE
Abstract: front page image
(EN)A multi-layer coating system comprising a hydroxyl-functional polyurethane dispersion is provided. The hydroxyl-functional polyurethane comprises the reaction product of a pre-polymer intermediate formed from the reaction of an isocyanate with an active hydrogen containing compound, such as a polyester polyol, with a compound having at least two amine groups and one hydroxyl group, such as a diamino alcohol. In addition, a waterborne basecoat composition is provided having improved rheology and pattern control. Such a waterborne basecoat composition comprises a hydroxyl-functional polyurethane dispersion, an acrylic emulsion resin, a water-reducible polyester resin, and a cellulose ester.
(FR)Cette invention concerne un système de revêtement multicouche comprenant une dispersion de polyuréthane à fonction hydroxyle. Le polyuréthane à fonction hydroxyle comprend le produit de réaction d'une part d'un intermédiaire pré-polymère formé par la réaction d'un isocyanate avec un composé contenant de l'hydrogène actif, tel qu'un polyester polyol, et d'autre part d'un composé comprenant au moins deux groupes amine et un groupe hydroxyle, tel qu'un alcool diamino. Cette invention concerne en outre une composition de couche primaire à l'eau qui présente une meilleure rhéologie et une meilleure commande de motif. Une telle composition de couche primaire à l'eau comprend une dispersion de polyuréthane à fonction hydroxyle, une résine en émulsion acrylique, une résine polyester réductible dans l'eau et un ester de cellulose.
