摘要： 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: R1 represents C1-C3 alkyl or C2-C3 alkenyl; R2 represents hydrogen, C1-C3 alkyl or C2-C3 alkenyl; R3 represents hydrogen, C1-C3 alkyl or C2-C3 alkenyl; R4 represents hydrogen, C1-C3 alkyl or C2-C3 alkenyl; R5 represents hydrogen, C1-C3 alkyl or C2-C3 alkenyl; and R6 represents hydrogen, C1-C3 alkyl or C2-C3 alkenyl, and (b) plasma polymerization of a compound of formula (I) and deposition of the resulting polymer onto the polymer formed in step (a).
