Abstract
An electrical component comprising an electrical component having an exterior protective layer on at least a portion of a surface. The layer is a cured copolymer of a reaction between at least one oligomer having a terminal ethylenically unsaturated group and at least one monomer having a terminal ethylenically unsaturated group. Alternatively, the layer is a cured copolymer of a reaction between at least two oligomers having a terminal ethylenically unsaturated group. The copolymerization reaction is preferably in the presence of a free radical initiator curing agent and a transition metal catalyst.
Claims19
An article comprising an electrical component having an outer surface, and a reenterable exterior protective layer on at least a portion of the outer surface wherein the layer comprises a gel of a cured copolymer formed by reaction between a first acrylate or methacrylate compound and a second acrylate or methacrylate compound, wherein the reaction is conducted in the presence of a free radical initiator of a peroxide or hydroperoxide compound, a transition metal catalyst and an extender of an acylated castor oil.
