Method for curing a silicone resin composition

摘要

A method for curing a silicone resin composition with heat, wherein the silicone resin composition comprises (A) an organopolysiloxane having at least two alkenyl groups per molecule, (B) an organohydrogenpolysiloxnae having, per molecule, at least two hydrogen atoms each bonded to a silicon atom, and (C) a photoactive catalyst, wherein the method is characterized by comprising a step of irradiating the silicone resin composition with light before the step of heating, the light has a maximum peak of irradiance in the region of wavelengths of 300 to 400nm and the irradiance of light of wavelength shorter than 300nm is 5 % or less of the irradiance at the maximum peak.
