Electrical components and method for the fabrication thereof

A method for fabricating electrical components having a surface of cured silicone thereon, comprising:

• (a) treating the surface of the cured silicone with a primer selected from the group consisting of:
• (i) a mixture of components (a) and (b),
• (ii) a reaction mixture of components (a) and (b),
• (iii) component (c),
• (iv) component (c) and a mixture of components (a) and (b), and
• (v) component (c) and a reaction mixture of components (a) and (b),
• where component (a) is silanol-functional organopolysiloxane;
• component (b) is epoxy-functional organoalkoxysilane;
• and component (c) is organopolysiloxane with the average unit formula:
• (R.sup.1 SiO.sub.3/2).sub.a (R.sup.2.sub.2 SiO.sub.2/2).sub.b (R.sup.2.sub.3 SiO.sub.1/2).sub.c (R.sup.3 O.sub.1/2).sub.d
• where R.sup.1 is an epoxy-functional monovalent organic group;
• each R.sup.2 is independently a monovalent hydrocarbon group, R.sup.3 is selected from the group consisting of hydrogen and alkyl groups of 1 to 4 carbon atoms;
• a, b, and d are each a positive number;
• and c is 0 or a positive number;
• (B) sealing the treated cured silicone with a resin sealant;
• and thereafter
• (C) curing the resin sealant.
