    摘要: The present invention concerns a process for the preparation of a silicone coating of low dielectric constant, comprising the following essential steps: a) a film-forming silicone composition is deposited on the surface of a substrate, said silicone composition comprising: (i) at least one crosslinkable film-forming silicone resin, (ii) at least one α,ω-hydroxylated, essentially linear silicone oil capable of degrading under the action of heat, and (iii) at least one solvent capable of rendering the silicone resin (i) compatible with the silicone oil (ii), b) the solvent (iii) is removed, preferably by heating, and, simultaneously or sequentially, c) the film-forming silicone composition is cured by heating. The invention deals also with a silicone coating obtained by this process and an integrated circuit comprising such a silicone coating as an electrical insulator.
