Abstract:
An addition-crosslinkable composition comprising a silicone polymer bearing unsaturated groups, a hydrosilylation catalyst, and a Siâ€”H functional polyorganosiloxane containing HM units (HR2Siâ€”O1/2), Q units (Siâ€”O4/2), T units (R1Siâ€”O3/2) and D units (R2Siâ€”O2/2) in a ratio HM:Q:T:D units of from 2:1:0:0 to 6:4:2:2, or containing HM units (HR2Siâ€”O1/2), T units (R1Siâ€”O3/2), D units (R2Siâ€”O2/2) and alkoxyM units (R2(R1O)Siâ€”O1/2) in a ratio HM:T:D:alkoxyM units of from 1:2:0:0 to 3:4:2:2,where R are identical or different, optionally halogenated hydrocarbon radicals having from 1 to 18 carbon atoms per radical, or are OR1, where R1 is a monovalent, optionally substituted hydrocarbon radical having from 1 to 8 carbon atoms, and wherein said organopolysiloxane contains at least 3 Si-bonded hydrogen atoms further comprising a vinyl-water glass resin.
