ABSTRACT:
The present invention relates to a hardenable organopolysiloxane composition having a viscosity of less than 30,000 Poise at 25.degree. 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 parts 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 organopolysiloxane composition to a substrate, exposing the composition and substrate to high energy radiation, and then applying a solid support to the coated substrate.
