containing curable composition capable of foaming by virtue of the blowing agent contained therein together with a curable liquid silicone composition the composition is suitable for the water repellent and waterproof treatment of fabric materials without decreasing the air and moisture permeability of the treated fabric material application_number US 48720283 A description the curable silicone composition used in the inventive foamable silicone containing composition comprises a liquid diorganopolysiloxane of substantially linear molecular structure having at least two functional groups bonded to the silicon atoms in a molecule as the base polysiloxane and a liquid organosilicon compound having in a molecule at least three functional groups capable of reacting with the functional groups in the base polysiloxane to form linkages with admixture of a suitable curing catalyst the functional groups in the base polysiloxane i e the liquid diorganopolysiloxane of linear molecular structure are exemplified by hydroxy group alkenyl groups e g vinyl and allyl groups epoxy group mercapto group and the like the diorganopolysiloxane should have at least two of these functional groups in a molecule on the other hand the functional groups in the liquid organosilicon compound to be used in combination with this base polysiloxane are exemplified by hydrogen atoms directly bonded to the silicon atoms vinyl group allyl group alkoxy groups acyloxy groups oxime groups aminoxy groups isopropenoxy group and the like the liquid organosilicon compound should have at least three of these functional groups in a molecule it is of course that the functional groups in the base polysiloxane and the functional groups in the liquid organic silicon compound to be combined therewith should be reactive with.
