Abstract
A curable organopolysiloxane composition comprises: (A) an alkenyl group-containing organopolysiloxane; (B) a compound having at least two thiol groups in a molecule; (C) an azo compound and/or an organic peroxide; and (D) at least one type of compound selected from the group consisting of quinone compounds, compounds having one or two aromatic hydroxyl groups in a molecule, compounds having one thiol group in a molecule, nitrosamine compounds, hydroxylamine compounds, and phenothiazine compounds. The curable organopolysiloxane composition can be quickly cured even at a relatively low temperature (e.g. of 80° C. or lower) to form a cured film with excellent adhesion to an object to be coated.
