Abstract
Disclosed herein is a composition comprising:A) a moisture curable polymer selected from the group consisting of silylated polyurethanes, silylated polyethers, and mixtures thereof, andB) a silicone oligomer of the formula:[R3SiO1/2]m[O1/2Si(R)2O1/2]n[SiO3/2R]o[SiO4/2]p  (I) wherein:each R is independently selected from the group consisting of B, R1, —OR2, R3, and R4;B is an organosilyl functional group bridged to the Si atom of the siloxane oligomer backbone by a Si—C bond;each R1 is independently a saturated or aromatic hydrocarbon group of 1 to 16 carbon atoms;each R2 is independently a group as defined for R1 or an acyl group;each R3 is independently a monovalent organic group containing an aliphatic unsaturated hydrocarbon group;each R4 is a monovalent organic group linked to the Si atom of the siloxane oligomer backbone by a Si—C bond that does not include an aliphatic unsaturated hydrocarbon group and that has thereon one or more members selected from the group consisting of ether polysulfide, ester, polyester, carbamate, polyurethane, isocyanurate, thioether, blocked mercaptan, amide, cyano, and oximato groups;with the provisos that at least on…
