Silicone/fluorinated organic compound mixed composition for conferring oleophobicity and/or hydrophobicity on a textile material

摘要

Crosslinkable liquid composition which can crosslink to give a hydrophobic and/or oleophobic silicone elastomer coating, comprising a polyorganosiloxane (POS) resin A exhibiting, per molecule, on the one hand, at least two different siloxyl units chosen from those of M, D, T and Q types, one of the units being a T unit or a Q unit, and, on the other hand, at least three hydrolysable/condensable groups of OH and/or OR¹ types, where R¹ is a linear or branched C₁ to C₆, preferably C₁ to C₃, alkyl radical, a system for promoting attachment B and a polyfluoroacrylate F. Use of this composition to form a silicone elastomer sheath around the constituent yarns, fibers and/or filaments of a textile material and to confer long-lasting oleophobicity and/or hydrophobicity properties.
