Star-branched silicone polymers as anti-mist additives for coating applications

摘要

A hydrido-silicone is incompletely reacted with (preferably) a long chain olefin under hydrosilylation conditions to produce a partially substituted hydrido-silicone that is further reacted under hydrosilylation conditions with a vinyl containing MQ resin to partially consume the remaining hydride species which is then reacted under hydrosilylation conditions to consume the remaining hydride species with a long chain di- or multi-alkenyl silicone to produce a composition that is useful as an anti-mist agent in the coating of flexible supports.
