Claim 3:
4. A method according to claim 1 wherein the crosslinker XL is a mixture containing:
a) at least one branched silicone resin comprising at least two, and optionally at least three, MH siloxy units of formula R2HSiO1/2 and TPh siloxy unit of formula (Ph)SiO3/2, formulas where Ph is a phenyl group, H is a hydrogen atom and where R is a one to forty carbon atom monovalent hydrocarbon radical, optionally a one to twenty carbon monovalent hydrocarbon radical, optionally selected from the group consisting of methyl, ethyl, propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, tert-butyl, pentyl, hexyl, heptyl, phenyl, benzyl, and mesityl; and optionally selected from the group consisting of methyl and phenyl, and
b) at least one linear organopolysiloxane B containing at least 3 silicon-bonded hydrogen atoms per molecule and/or a branched MHQ silicone resin comprising at least two, and optionally at least three, MH siloxy units of formula R2HSiO1/2 and Q siloxy unit of formula SiO4/2, formulas where H is a hydrogen atom and where R is a one to forty carbon atom monovalent hydrocarbon radical, optionally a one to twenty carbon monovalent hydrocarbon radical, optionally selected from the group consisting of methyl, ethyl, propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, tert-butyl, pentyl, hexyl, heptyl, phenyl, benzyl, and mesityl; and optionally selected from the group consisting of methyl and phenyl.
