ABSTRACT:
An implosion-protected evacuated glass enclosure such as a cathode ray tube or an electric lamp is disclosed. The enclosure is made implosion resistant by depositing on the exterior surface thereof a polyurethane film. The mechanical properties of the polyurethane film result in outstanding glass retention properties when the evacuated glass enclosure implodes.
