Abstract: The invention relates to the use of an amphilic block copolymer, comprising at least one hydrophic bloc and at least one hydrophobic block, in order to create a low-energy surface such as a plastic or thermoplastic polymer based surface, a deposit increasing the affinity of said surface with regard to water. Said deposit can be used to increase the efficiency of a filmogenic, aqueous composition which is later applied to the surface thus modified. The invention also relates to a method for applying paint or mastic compositions on a low-energy surface, highlighting the use thereof, in addition to coated plastic or thermoplastic type materials which can be obtained according to said application method.

Abstract: The invention concerns the use of amphiphilic block copolymer, comprising at least a hydrophilic block and at least a hydrophobic block, as additive for film-forming aqueous compositions such as, in particular, paint, latex or sealant optionally containing silicone to provide or promote adhesion to said compositions on a low-energy surface such as a plastic or thermoplastic polymer surface. The invention also concerns the film-forming aqueous compositions comprising said amphiphilic block copolymers.
