摘要

Aqueous emulsions of crosslinkable polyaddition organopolysiloxane compositions, well adapted for the thin layer coating of flexible substrates to impart water-repellency and nonadherency thereto, comprise a first aqueous emulsion A including end-vinylated polysiloxanes, a vinylated cyclotrisiloxane, a hydroorganodiorganopolysiloxane, a polyvinyl alcohol and a polyalkylene glycol alkyl ether or alkylphenyl ether, and a second aqueous emulsion B which comprises a catalytically effective amount of a platinum group metal catalyst.
