An electrical assembly which has a conformal coating, wherein said conformal coating comprises layers of polymer formed from a substituted benzene of formula I substituted by at least one C1-C3 alkyl or C2-C4 alkenyl group (such as dimethylbenzene, styrenes and divinylbenzenes) and an additional layer of a polymer formed from fluorohydrocarbons / saturated or unsaturated fluorocarbons. The polymers may be formed by plasma polymerization, and maybe be formed in multiple alternating layers. R1 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, Ci-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. |
