More Information
Summary:The organopolysiloxane composition of the present invention includes at least (A) an organopolysiloxane expressed by an average unit formula, having a silicon-bonded hydroxyl group, (B) an organopolysiloxane expressed by an average unit formula, which is different from compound (A), and (C) a compound having at least two functional groups selected from ether bonds, ester bonds, and alkoxysilyl groups expressed by a formula, in one molecule, where the amount of compound (A) is 2 to 70 mass% of the sum of component (A) and component (B), and the amount of component (C) is an amount where the sum of functional groups in component (C) is 0.05 mols or more with regard to 1 mol of silicon-bonded hydroxyl groups in component (A). The composition has sufficient thixotropic properties, independent of inorganic powders such as fumed silica, precipitated silica, alumina, titanium oxide, and the like.
