Claim 1, which is representative of the subject matter on
appeal, reads as follows:
1. An aqueous silicone dispersion crosslinkable into
elastomeric state by elimination of water therefrom under
ambient conditions, comprising:
(A) 100 parts by weight of an oil-in-water emulsion of an
"-T-(dihydroxy)polydiorganosiloxane stabilized with at least
one anionic or nonionic surface-active agent, or mixture
thereof;
(B) 1 to 100 parts by weight of an hydroxylated silicone
resin containing, per molecule, at least two different
recurring structural units selected from among those of the
formulae: (R) SiO , (R) SiO, RSiO and SiO , wherein the3 0.5 2 1.5 2
radicals R, which may be identical or different, are vinyl,
phenyl or 3,3,3,-trifluoropropyl radicals or linear or
branched chain alkyl radicals containing from 1 to 6 carbon
atoms, said resin having a hydroxyl group weight content of
from 0.1% to 10%;
(C) 0 to 250 parts by weight of a nonsiliceous inorganic
filler;
(D) 0.01 to 3 parts by weight of a metal curing catalyst
compound; and
said dispersion having a solids content of at least 40%.
