USE OF AMPHILIC BLOCK COPOLYMERS IN ORDER TO INCREASE THE WATER AFFINITY OF LOW-ENERGY SURFACES

摘要

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.
