Abstract (en)

[origin: FR2780407A1] Crosslinkable silicone composition is used to make water- and/or oil-repellent coatings with low surface energy. Crosslinkable silicone composition used to make water- and/or oil-repellent coatings with low surface energy comprises: at least a perfluorinated POS, A; at least a crosslinking agent, B, perfluorinated or not, and capable of reacting with A; optional catalyst, C, for the reaction(s) between A and B; and, optionally, one or more functional additives, D; in which each molecule of A has one or more perfluorinated grafts, Gf, of formula (I) -(CH2)m-CR<1>(COORf2)((CR<1>2-)n-COORf1) (I) R<1> = H or 1 - 6 C alkyl; Rf1 and Rf2 = perhalogenated, preferably perfluorinated radicals and most preferably -CqF2q-CF3 where q \- 0 (II) or CqF2q-H where q \- 1 (III); m = 1 - 10; n = 0 -4; and one or more crosslinking functions, Fra; and each molecule of B has at least 2 crosslinking functions, Frb, which can react with Fra. Independent claims are also included for a POS constituent of said composition; and method for making coatings using said composition.
