Abstract
A release-modifier composition comprises a capped polydiorganosiloxane-(MQ resin) copolymer, which comprises a macromolecule having an MQ resin portion covalently bonded to a polydiorganosiloxane portion. An M unit typically has the formula R1SiO1/2 and a Q unit typically has the formula SiO4/2, wherein R1 is an independently selected substituent. The polydiorganosiloxane portion comprises two D segments coupled to each other via a (RV,Alkenyl)SiO2/2 unit, wherein RV is (C1-C6)hydrocarbyl. Alkenyl may be (C2-C6)alkenyl. Each D segment comprises two or more (RD)2SiO2/2 units, which independently may be the same as or different than each other. Each RD independently may be (C1-C6)alkyl, (C3-C6)cycloalkyl, or phenyl. A curable release-coating composition comprising or prepared from the release-modifier composition, cured release-coating composition, coatings comprising the same, manufactured articles, kits, methods and uses, are also disclosed.
