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 RSiOand a Q unit typically has the formula SiO, wherein Ris an independently selected substituent. The polydiorganosiloxane portion comprises two D segments coupled to each other via a (R,Alkenyl)SiOunit, wherein Ris (C-C)hydrocarbyl. Alkenyl may be (C-C)alkenyl. Each D segment comprises two or more (R)SiOunits, which independently may be the same as or different than each other. Each Rindependently may be (C-C)alkyl, (C-C)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.
