WATER CURABLE COMPOSITIONS of the Invention A water curable composition comprising: (a) at least one polymer selected from the group consisting of silane grafted homopolymers of ethylene, propylene, or 1-butene; silane grafted copolymers wherein a major propotion thereof is attributed to an ethylene, propylene, or 1-butene monomer; and a copolymer wherein a major proportion thereof is attributed to an ethylene, propylene, or 1-butene monomer and a minor proportion thereof is attributed to silane, each polymer having at least one silane moiety containing at least one hydrolyzable group; and (b) at least one polysiloxane having the following formula: <IMG> wherein: R = C3H6(OC3H6)y(OC2H4)zOR' R' = a radical selected from the group consisting of hydrogen, an alkyl radical having 1 to 4 carbon atoms, an alkyl acetate ester radical wherein the alkyl group has 1 to 4 carbon atoms, and a trimethyl silyl radical, and each R' is alike or different w = about 20 to 120 x = 0 to about 24 y = 0 to about 10 z = about 4 to 25 y+z = about 5 to 30, and (c) at least one silanol condensation catalyst.
