Abstract
A device e.g., an electrical or electromechanical assembly (62), comprising a housing (64) with a mechanism (66) disposed therein which is potted by a cured mass of self-leveling liquid composition. The composition comprises an actinic radiation cured first resin component (102) preferably (methacrylate resins, which immobilize the partially cured mass, and a subsequently cured second resin component (100), preferably epoxy resins, which is non-cured under the actinic radiation but curable at ambient or elevated temperature. Depending on the depth of the composition which is to be cured in the housing, it may be desirable to utilize the self-leveling liquid composition as either a single homogeneous mixture of the first and second resin components, or, where the depth of the housing is greater than the depth of UV penetration, as cured mass wherein the first resin component is in a separate and discrete resin layer overlying a lower resin layer containing the second resin component but not the first resin component.
