METHOD FOR PREVENTION OF BUBBLE FORMATION IN POLYORGANOSILOXANE GELS Abstract Bubble formation at the interface between an organosiloxane gel that is curable by a hydrosilation reaction and a substrate possessing potential nucleation sites for bubbles can be prevented if the substrate is first coated with an uncured extrudable silicone rubber composition that is curable by hydrosilation reaction in addition to being compatible with and adherent to the gel. The gel is then applied over the uncured silicone rubber composition and the two materials are concurrently cured. The cured rubber composition exhibits a durometer hardness value of at least 10 on the Shore A scale.
