  • Patent number: 9714308
    Abstract: A copolymer includes a first group that is hydrophobic and a second group that is crosslinkable. Moreover, a glass substrate includes a coating of the copolymer, with interposition of a layer of silane including a functional group capable of reacting with the crosslinkable group. The glass substrate may be used as hydrophobic glazing for a transport vehicle, shower cubicle wall or easy-to-clean interior glazing.
