Addition-curable polysiloxane compositions for coating flexible materials.

摘要

Organopolysiloxane composition capable of being crosslinked by a hydrosilylation reaction in a thin layer for coating flexible material, comprising a vinylated organopolysiloxane, a hydrogenated organopolysiloxane and a platinum group metal catalyst, characterised in that between 0.5 and 60 % of the number of the vinyl groups are contributed by a vinylorganocyclotrisiloxane. The composition can be used more particularly for making a flexible support, in particular paper sheets, antiadhesive.
