摘要: A solventless curable silicone release composition contains (A) a branched organopolysiloxane having a vinyl group attached to a silicon atom at an end of its molecular chain, (B) an organohydrogenpolysiloxane having at least three SiH groups in a molecule, and (C) a platinum group metal catalyst. The composition is easily applicable to a thin gage and cures into a releasable silicone coating ensuring light release at high speeds. A release sheet having the cured coating formed thereon has improved release characteristics.
