ABSTRACT:
A process for the formation of a protective coating on an electrical element which comprises housing an electrical element such as a capacitor in a mold made of a ultraviolet rays transmissible material, introducing a fire retardant liquid resin composition into the space between the mold and the electrical element to enclose the element with the composition and then perfectly curing the liquid resin composition by firstly irradiating ultraviolet rays on the composition for partial cure thereof and secondly heating the partially cured composition for complete cure thereof thus forming a protective coating on the electrical element.
