Abstract

L'invention concerne une dispersion aqueuse à base de copolymères d'éthylène-ester vinylique. Cette dispersion polymère aqueuse présente une bonne stabilité au stockage à long terme et diminue le phénomène de marque d'eau sur le film de revêtement lorsque celui-ci est utilisé dans des enduits à l'eau de bâtiment. En particulier, sur le film formé à partir de peintures en émulsion aqueuse en présence d'humidité, la dispersion permet une réduction du nombre, de la couleur et du brillant des marques d'eau.
