Release Modifier And Release Coating Organopolysiloxane Composition |
摘要 |
To provide a release modifier which provides a heavy release force to a cured release layer of silicone coating composition. The release modifier comprises an organopolysiloxane resin-organopolysiloxane condensation reaction product that is obtained by the condensation reaction of (a1) 100 weight parts of MQ-type organopolysiloxane resin in which the molar ratio of the M unit to the Q unit is 0.6 to 1.0 and the content of the hydroxyl group or alkoxy group is 0.3 to 2.0 weight % with (a2) 20 to 150 weight parts of chain-form diorganopolysiloxane that has an average degree of polymerization of 100 to 1000 and at least one hydroxyl group or alkoxy group; this organopolysiloxane resin-organopolysiloxane condensation reaction product preferably has a prescribed hydroxyl group content. |
