<p>A one-part organopolysiloxane gel composition comprising: (A) an organopolysiloxane comprising 80.0 to 97.0 mol% of a R2SiO unit, 1.0 to 10.0 mol% of a RSiO1.5 unit, 0.1 to 4.0 mol% of a (CH3)2(CH2=CH)SiO0.5 unit, and 0.5 to 10 mol% of a (CH3)3SiO0.5 unit; (B) an organohydrogenpolysiloxane having at least two units each represented by the formula H(R1)2SiO0.5 per molecule; and (C) a platinum complex having aβ-diketone platinum complex or a cyclic diene compound as a ligand. According to the present invention, it becomes possible to impart long-term storage stability to the composition, and it also becomes possible to uniformly cure even a part of the composition which cannot be exposed to light at a temperature of 50°C or lower by irradiating the composition with light having a wavelength of 200 to 500 nm, then applying the light-irradiated composition to a desired place and then curing the applied composition.</p> |
