A method of making a permeation-resistant silicone elastomer-containing laminate useful for making fluid-containing implants such as mammary prostheses and gastric balloons. The method is accomplished by (a) applying a layer of an unvulcanized heat-curable silicone elastomer composition to a cured silicone elastomer substrate, (b) applying a layer of a solvent dispersion of a permeation-resistant elastomer and a solvent on the layer of unvulcanized silicone elastomer composition to form a three-layered laminate, and (c) exposing the three-layered laminate to heat until the unvulcanized silicone elastomer composition is vulcanized. The unvulcanized silicone elastomer composition must be bondable to the cured silicone elastomer substrate, the permeation-resistant elastomer is selected from the group consisting of polyurethane, silicone-polyurethane copolymer, and silicone-polycarbonate copolymer, and the permeation-resistant elastomer solvent must be compatible with both the permeation-resistant elastomer and the unvulcanized silicone elastomer composition.
