A process for the manufacture of a multilayer silicone structure of cured silicone elastomer layers wherein the compositions of each of the curable silicone elastomers are chosen such as to provide excellent layer-to-layer adhesion of the said cured silicone elastomer layers, that is, the layers do not suffer from cohesive failure. The multilayer silicone structures may be used for example for the manufacture of electronic devices, coatings, shaped molded articles, laminates, etc.
