Abstract (en)

[origin: WO2020174188A1] Composition crosslinkable under the effect of UV radiation to produce a hydrophobic coating on a glazing substrate, said composition being characterized in that it comprises: a) between 80 and 98% by weight of at least one oligomer of an organofunctional compound of a metal A selected from Si, Ti, Zn, Zr, Al, Ce, V, Nb or Y or of an InSn metal alloy and comprising the following alternation: [(RO)2AO]n (I) in which: - A is selected from Si, Ti, Zn, Zr, Al, Ce, V, Nb or Y or an InSn alloy; - R is a linear, branched or aromatic, preferably linear, carbon chain R in which preferably the number of carbons is between 1 and 6, endpoints included, preferably between 1 and 3, endpoints included, - n is between 2 and 20, preferably between 4 and 10, b) between 0.1 and 5% by weight of a photoacid generator compound PAG, c) between 1 and 15% by weight of a compound comprising a hydrophobic group.
