Zusammenfassung:Provided is an oxygen-curable silicone composition that cures at room temperature, the reaction being triggered by oxygen in the atmosphere, without requiring heat or UV irradiation at the time of use, and exhibits good mechanical strength after curing.A composition including(A) an organopolysiloxane (1)(R1 represents an alkyl group or the like but has at least one acryloyloxy group or the like in the molecule, R2 represents an oxygen atom or the like, and m and n represent numbers that satisfy 1 ≤ m + n ≤ 1,000.),(B) a silicone resin including (a) a unit of formula (2), (b) an R13SiO1/2 unit, and (c) an SiO4/2 unit, the molar ratio of [(a) + (b)]/(c) being 0.4-1.2, and the silicone resin having 0.005 mol/100 g or more Si-OH groups(R1 and R2 are the same as above. R3 represents an acryloyloxyalkyl group or the like, p represents 0-10, and 1 represents a number that satisfies 1-3.), and(C) an organoborane complex (3)(R4-R6 represent hydrocarbon groups.).
