1. A method for coating a silicone composition X which is crosslinkable by polyaddition reaction to form a silicone elastomer on an open-work and/or elastic textile medium S, comprising a), b) and c):
a) a silicone composition X which is crosslinkable by polyaddition reactions is provided, comprising:
at least one organopolysiloxane A having, per molecule, at least two C2-C6 alkenyl groups bonded to the silicon,
at least one organopolysiloxane B having, per molecule, at least two SiH units, and
a catalytically effective amount of at least one hydrosilylation catalyst C, which is activatable by UV irradiation,
b) said silicone composition X is deposited continuously or discontinuously on at least one face of said textile medium S, and
c) said silicone composition X is crosslinked by irradiation with UV radiation, a source of which is a UV-LED lamp.
