Abstract
Bubble migration from a surface of a container or other substrate into a polyorganosiloxane gel that is in contact with the surface can be substantially eliminated by coating the surface with a liquid composition comprising an organohydrogensiloxane containing at least three silicon-bonded hydrogen atoms per molecule. The liquid composition is covered with a layer of uncured silicone rubber that is curable by hydrosilation reaction in addition to being compatible with and adherent to the polyorganosiloxane gel. The gel is then placed over the uncured silicone rubber, after which the rubber and gel are concurrently cured. The cured silicone rubber exhibits a durometer hardness value of at least 10 on the Shore A scale, and the layer of silicone rubber is at least 3 mm. thick.
