Patent ID: 8216321

Claim:
A crosslinkable liquid composition which crosslinks to give a hydrophobic and/or oleophobic silicone elastomer coating, comprising a polyorganosiloxane resin (component A) comprising, per molecule, at least two different siloxyl units selected from the group consisting of (R 3 ) 3 SiO 0.5 (M unit), (R 3 ) 2 SiO (D unit), R 3 SiO 1.5 (T unit), and SiO 2 (Q unit), wherein each R 3 is independently selected from the group consisting of a linear or branched C 1 to C 6 alkyl radical, a C 2 to C 4 alkenyl radical, a phenyl radical or a 3,3,3-trifluoropropyl radical, one of the units being a T unit or a Q unit, and at least three hydrolysable/condensable groups of OH and/or OR 1 types, where R 1 is a linear or branched C 1 to C 6 alkyl radical; at least one component B, wherein component B comprises: either component B-1, at least one metal alkoxide of general formula: M[(OCH 2 CH 2 ) a OR 2 ] n (I) in which: M is a metal selected from the group consisting of: Ti, Zr, Ge, Si, Mn and Al; n=valency of M; the R 2 substituents, which are identical or different, each represent a linear branched C 1 to C 12 alkyl radical; a represents zero, 1 or 2; wherein when a represents zero, the alkyl radical R 2 has from 2 to 12 carbon atoms and, when a represents 1 or 2, the alkyl radical R 2 has from 1 to 4 carbon atoms; optionally the metal M is connected to a ligand; or component B-2, at least one metal polyalkoxide resulting from the partial hydrolysis of the monomeric alkoxides of formula (I) mentioned above in which R 2 has the abovementioned meaning with the symbol a representing zero; or a combination of component B-1 and component B-2; or component B-3, at least one optionally alkoxylated organosilane comprising, per molecule, at least one C 2 -C 6 alkenyl group, component B 3/1, and/or at least one organosilicon compound comprising at least one epoxy, amino, ureido, isocyanato and/or isocyanurate radical, component B 3/2; or component B-4, a combination of component B-1 with component B 3/1 and/or component B 3/2, a combination of component B-2 with component B 3/1 and/or component B 3/2, or a combination of component B-1 and component B-2 with component B 3/1 and/or component B 3/2; and a polyfluoroacrylate (component F).
