Abstract

The present invention relates to an electrical assembly which has a conformal coating, wherein said conformal coating is obtainable by a method which comprises: (a) plasma polymerization of a compound of formula (I) and a fluorohydrocarbon, wherein the molar ratio of the compound of formula (I) to the fluorohydrocarbon is from 5:95 to 50:50, and deposition of the resulting polymer onto at least one surface of the electrical assembly: wherein: Rrepresents C-Calkyl or C-Calkenyl; Rrepresents hydrogen, C-Calkyl or C-Calkenyl; Rrepresents hydrogen, C-Calkyl or C-Calkenyl; Rrepresents hydrogen, C-Calkyl or C-Calkenyl; Rrepresents hydrogen, C-Calkyl or C-Calkenyl; and Rrepresents hydrogen, C-Calkyl or C-Calkenyl, and (b) plasma polymerization of a compound of formula (I) and deposition of the resulting polymer onto the polymer formed in step (a).
