Abstract:
1. A method for producing a silicone resin sheet comprising a step of molding a silicone resin composition into a sheet, and then thereafter heating the sheet at 40 to 150° C. for 0.1 to 120 minutes to semi-cure the sheet, wherein the silicone resin composition comprises: (1) an organopolysiloxane having at least two alkenylsilyl groups in one molecule, (2) an organopolysiloxane having at least two hydrosilyl groups in one molecule, (3) a hydrosilylation catalyst, and (4) a curing retarder, wherein the curing retarder contains tetraalkylammonium hydroxide, and the tetraalkylammonium hydroxide content is 10 to 500 mol relative to 1 mol of the hydrosilylation catalyst.
