The present invention relates to a hardenable organopolysiloxane composition having a viscosity of less than 30,000 Poise at 25°C comprising (A) 30 to 75 wt% of a silicone resin, (B) 70 to 25 wt% of a mercapto functional organopolysiloxane, (C) 0.1 to 10 parts by weight per 100 part by weight of (A)+(B) of a mercapto functional organosilane, and (D) 0.01 to 10 parts by weight per 100 parts by weight of (A)+(B) of a condensation catalyst. The present invention also relates to an article of manufacture obtained by applying the hardenable oganopolysiloxane composition to a substrate, exposing the composition and substrate to high energy radiation, and then applying a solid support to the coated substrate.
Composition d'organopolysiloxane possédant une viscosité inférieure à 30 000 poises à 25 °C et renfermant (A) 30 à 75 % d'une résine de silicone, (B) 70 à 25 % en poids d'un organopolysiloxane à fonction mercapto, (C) 0,1 à 10 parties par 100 parties en poids de (A)+(B) d'un organosilane à fonction mercapto, et (D) 0,01 à 10 parties par 100 parties en poids de (A)+(B) d'un catalyseur de condensation. La présente invention porte également sur un article de fabrication obtenu en appliquant la composition d'organopolysiloxane sur un substrat, en exposant la composition et le substrat à un rayonnement haute énergie, puis en appliquant un support solide au substrat enrobé.
