Abstract
An epoxy formulation is provided with improved properties for electrical components exposed to a voltage differential. The improved electrical properties include increased glass transition temperature, increased breakdown strength and/or lower loss factor. Electrical components may be formed from the epoxy formulation by 3D printing the epoxy formulation and curing the formulation with UV radiation. The epoxy formulation includes epoxy, a photoinitiator and an accelerator.
