Abstract
A UV-curable silicone composition includes a polyorganosiloxane (A) containing at least one alkenyl group in the molecule and having an alkenyl group content of 0.3 mmol/g or less on average; a polyorganohydrogensiloxane (B) having at least three silicon-bonded hydrogen atoms in the molecule; and a UV-active platinum catalyst (C).
Claims9
A UV-curable silicone composition comprising:
- a polyorganosiloxane (A) containing at least one alkenyl group in the molecule and having an alkenyl group content of 0.3 mmol/g or less on average;
- a polyorganohydrogensiloxane (B) having at least three hydrogen atoms bonded to silicon atoms in the molecule;
- and
- a UV-active platinum catalyst (C),
- wherein:
- the component (A) comprises only a linear polyorganosiloxane having one alkenyl group at each terminal of the molecular main chain, and
- the component (B) comprises only a polyorganohydrogensiloxane (B1) containing an Rc12HSiO1/2 unit (wherein Rc1 independently at each occurrence is a C1-C6 alkyl group or a C6-C20 aryl group) and a SiO4/2 unit.
