Abstract
(EN)
A curable composition including: at least one polyorganosiloxane including at least one hydrosilyl moiety (in certain embodiments, two different polyorganosiloxanes); at least one silane including hydrolyzable functionality; and at least one base selected from an amidine, a guanidine, a phosphazene, a proazaphosphatrane, and a combination thereof; a method of coating such curable composition; and an article having a substrate surface with a coating formed from such method.
(FR)
L'invention concerne une composition durcissable contenant : au moins un polyorganosiloxane contenant au moins un fragment hydrosilyle (dans certains modes de réalisation, deux polyorganosiloxanes différents) ; au moins un silane contenant une fonctionnalité hydrolysable ; et au moins une base choisie parmi une amidine, une guanidine, un phosphazène, un proazaphosphatrane et une combinaison de ces derniers ; un procédé d'application de cette composition durcissable ; et un article comportant une surface de substrat munie d'un revêtement formé par un tel procédé.
