ABSTRACT:
A method of forming a gas seal without molds is provided by the use of a chemically modified silicon rubber that is rapidly polymerized upon exposure to ultraviolet radiation. The aft end of the sabot is coated with the rubber compound using spraying or flow coating technologies. The coating layer is deposited to a desired thickness. Then the coating layer is exposed to ultraviolet radiation which causes the polymerization of the silicone rubber compound. A hard, cured gas seal is produced by the polymerization reaction.
