| 摘要 |
The invention pertains to a fluoropolymer composition suitable for adhering a fluoropolymer coating onto a surface, in particular onto a metal surface, said composition comprising: at least one fluoropolymer [polymer (A)]; at least one aromatic polycondensation polymer [polymer (P)]; a solvent mixture [mixture (M)] comprising dimethylsulfoxide (DMSO) and at least one solvent selected from the group consisting of diesters of formula (Ide) and ester-amide of formula (1ea): R1—OOC-Ade-COO—R2 (1de), R1—OOC-Aea-CO—NR3R4 (1ea) wherein: R1 and R2, equal to or different from each other, are independently selected from the group consisting of C1-C20 hydrocarbon groups; R3 and R4, equal to or different from each other, are independently selected from the group consisting of hydrogen, C1-C36 hydrocarbon groups, possibly substituted, being understood that R3 and R4 might be part of a cyclic N moiety including the nitrogen atom to which they are bound, said cyclic moiety being possibly substituted and/or possibly comprising one or more than one additional heteroatom, and mixtures thereof; Ade and Aea, equal to or different from each other, are independently a linear or branched divalent alkylene group, and to a method for coating a surface, specifically a metal surface, with a fluoropolymer, using said fluoropolymer composition. |
