ABSTRACT:
A lamp capping cement for electric lamps comprises a resin component consisting essentially of a condensation product of an aralkyl ether and a phenol mixed with a cross-linkable polymer or resin, a heat-resistant filler component, and a liquid diluent. The preferred cross-linkable polymer is a carboxylated acrylic polymer which may constitute 1 to 15% of the cement. This cement is capable of withstanding higher operating temperatures in incandescent filament lamps without breakdown.
