ABSTRACT:
A novel photocurable organopolysiloxane composition is proposed capable of giving a cured product having a very high anti-moisture resistance even at an elevated temperature to withstand a treatment in boiling water for 1 hour or longer without coming off from the substrate surface on which it has been applied and cured by irradiation with light. The composition comprises a specific acryloyloxy-containing organopolysiloxane as the base component, an epoxy compound and a photosensitizer. The composition is suitable, for example, for providing a moisture-proof overcoating on various electronic parts such as a capacitor.
