Solventless cured release coating-forming organopolysiloxane composition and sheet-form substrate having cured release coating

摘要

A solventless, cured release coating-forming organopolysiloxane composition comprising (A) 100 parts of an organopolysiloxane fluid having a branched structure and comprising (i) the siloxane unit represented by the formula SiOSUB4/2/SUB, (ii) the siloxane unit represented by the general formula RSUB2/SUBSiOSUB2/2/SUB, and (iii) the siloxane unit represented by the general formula RSUPa/SUPRSUB2/SUBSiOSUB1/2/SUB; (B) 0.5 to 15 parts of a diorganopolysiloxane with the average structural formula RSUPa/SUPRSUPc/SUP SUB2/SUBS
