A photocurable organopolysiloxane composition.

摘要

The photocurable organopolysiloxane composition comprises (A) a diorganopolysiloxane of which each of the terminal silicon atoms has 2 or 3 vinyl groups bonded thereto, (B) an organohydrogenpolysiloxane as a crosslinking agent, (C) a platinum compound as a catalyst for promoting the addition reaction between the vinyl groups in (A) and the silicon-bonded hydrogen atoms in (B), and (D) a photosensitzer. By virtue of the synergistic effect of the components, the composition is advantageous in the high sensitvity to photo-induced curing and stability.
