Abstract:
Use for the preparation of paints for substrata coatings of aqueous dispersions of VDF-based polymers having an average particle size between 0.260 and 0.3 micrometers comprising a bifunctional surfactant of formula: A-Rf-B (I) wherein A=—O—CFX—COOM; B=—CFX—COOM with X=F, CF3;M=NH4, alkaline metal, H;Rf is a linear or branched perfluoroalkyl chain, or a (per)fluoropolyether chain such that the number average molecular weight of (I) is in the range 600-800.
