SILICONE COMPOSITION FOR MOLD RELEASE

摘要

PURPOSE:To make mold release between a mold and a cured matter of liquid silicone easy, by limiting polyorganohydrodienesiloxane of a crosslinking agent to a certain kind. CONSTITUTION:Polyorganosiloxane of a component (A) possesses at least two pieces of alkenyl groups in one molecule bonded to a silicon atom, which may be a straight-chainlike state or a ramified state or a mixture of them. Polyorganohydrodienesiloxane of a component (B) displayed by a formula (I) forms a cured film by performing crosslinking reaction to the polyorganosiloxane of the component (A) and it is necessary that the sum of the alkenyl groups in the one molecule of the component (A) and SiH groups in one molecule of the component (B) is at least 5. The component (B) is used within a range of 0.1-150 pts.wt. on the basis of 100 pts.wt. component (A).
