The present invention is directed to a method of producing a waterborne isocyanate-modified acrylic polymer. The method provides for reacting a compound having at least two-isocyanate functionalities with an isocyanate-reactive polymer to produce the isocyanate-modified acrylic polymer of the present invention having extended shelf stability and solvent resistance.
Méthode pour l'obtention d'un polymère acrylique aqueux modifié par un isocyanate. Elle consiste à faire réagir un composé renfermant au moins deux fonctions isocyanates avec un polymère réagissant aux isocyanates, pour l'obtention du polymère acrylique modifié par l'isocyanate de l'invention, lequel possède une durée de conservation plus longue et une meilleure résistance aux solvants.
