A composition comprising at least one vinylidene fluoride (VDF) polymer [polymer (F)]; and inorganic particles at least partially coated with at least one perfluoropolyether block copolymer [polymer (E)] comprising: A) one or more (per)fluoropolyoxyalkylene segment (chain Rf), comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety, and B) one or more polyalkylene segment (chain Ra) comprising recurring units of formula: —(CR1R2—CR3R4)—, wherein R1, R2, R3, R4, equal to or different from each other, are selected from the group consisting of H, halogens (preferably F, Cl); C1-C6 (hydro)carbon groups, optionally containing fluorine or other heteroatoms, referably perfluoroalkyl or (per)fluorooxyalkyl. The invention also discloses a method of coating various substrates using said composition. |
