ABSTRACT:
A dielectric composition capable of being polymerized for use in sealing electrical and electro-optical connectors and devices is disclosed. Said composition is comprised of a major proportion of vinyl ester resins, a minor proportion of polymerizable acrylic diluent monomers, and a polymerization activation system comprised of from about 0.25 percent to about 17 percent by weight of the resin. A process of the present invention includes applying a layer of said composition to desired areas or to desired locations such as apertures surrounding electrical terminals extending from a connector housing, and exposing said composition to actinic radiation which activates the polymerization activation system which causes the composition to polymerize to form a sealant material that exclused solder and solvents from the connector and its apertures.
