POLYORGANOSILOXANE COMPOSITION AND CURED BODY THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a polyorganosiloxane composition with a high heat resistivity and a low load given to the environment and to provide its cured body. SOLUTION: The polyorganosiloxane composition includes (A) a polyorganosiloxane in which at least one end in the molecule is a polyorgano-siloxane modified with silanol, (B) 0.3-3 mol of a silicon alkoxide per mol of the organosiloxane, as a crosslinking agent for crosslinking the polyorganosiloxane, and (C) 0.05-2 mol of hydroxyacetone per mol of the polyorganosiloxane.
