A hydrido-silicone resin is incompletely reacted with an olefin under hydrosilation conditions to produce a partially substituted hydrido-silicone that is further reacted under hydrosilylation conditions with a vinyl containing silicone to consume the remaining hydride species to produce a composition that is useful as an anti-mist agent in the coating of flexible supports.
L'invention concerne une composition obtenue selon un procédé consistant à faire réagir partiellement une résine d'hydruro-silicone avec une oléfine dans des conditions d'hydrosilylation pour produire une hydruro-silicone partiellement substituée, puis à faire réagir celle-ci avec du vinyle contenant de la silicone dans des conditions d'hydrosilylation pour consommer les espèces d'hydrure restantes et ainsi produire une composition pouvant être utilisée comme un agent anti-buée sur des supports flexibles.
