| 摘要 |
The present invention relates to a coating composition, comprising: at least one polymeric binder; at least one dispersion medium; at least one (per) fluorosurfactant; and optionally one or more further components of coating compositions known per se; which composition is characterised in that said (per) fluorosurfactant is a perfluoroether surfactant, and in particular a perfluoropolyether surfactant. The coating composition is preferably in the form of an aqueous dispersion, and may for instance be a paint or coating for household or industrial use, or a specialized coating composition. The coating compositions thus obtained have low surface energy (less than 30 Nm-1, preferably 20 Nm-1, in particular 16-18 Nm-1), excellent physical and/or chemical resistance, and good stability. The coatings can also be cured at low(er) temperatures, compared to conventional PTFE-based coatings. |
