An electrical part is disclosed comprising an electrical element, a cured siliconenresin treated by ultraviolet light. and a cured sealing resin that is integrally bonded to saidnUV treated silicone resin. The curable silicone resin is prepared from an addition curablensilicone composition that is a mixture of (a) an organosiloxane with silanol groups and (b)nan alkoxysilane with epoxy, groups, and/or (c) an organosiloxane expressed by the formulanR 1 SiO 3/2 ) a (R 2 2 SiO 2/2 ) b (R 2 3 SiO 1/2 ) c (R 3 O 1/2 ) d , wherein R 1 is an epoxy containing monovalentnorganic group, R 2 is monovalent hydrocarbon group, R 3 is hydrogen atom or an alkyl groupnof 1 to 4 carbon atoms, a, b and d are > 0 and c is ≥ 0. A method for manufacturing saidnelectrical part is also disclosed and comprises the steps of: (I) covering an electricalnelement with the above curable silicone composition; (ii) curing said composition to form ancured silicone resin; (iii) subjecting the cured silicone resin to ultraviolet irradiationntreatment; and (iv) sealing said cured silicone resin with a sealing resin. |
