Method of sealing electrical connectors using a broad spectrum light and heat curable composition

摘要

An electrical connector of the type having a housing with terminals extending from apertures thereof, is sealed at the aperture entrances around the extending terminal portions. The sealant material is polymerized of a major proportion of at least one vinyl ester resin, a minor proportion of at least one polymerizable acrylic diluent monomer and a polymerization activation system comprising from about 0.025% to about 17% by weight of the resin, by being exposed to actinic radiation selected to activate the system. The polymerized material excludes solder and solvents from the aperture entrances.
