Abstract

La présente invention concerne des procédés de préparation de compositions réactives qui permettent d'obtenir une étanchéité instantanée. Plus spécifiquement, selon les procédés de la présente invention, un polydiorganosiloxane fonctionnalisé par des hydroxy est mis en réaction avec un silane trifonctionnel en C1 pour former un polyorganosiloxane à chaîne prolongée. Le polyorganosiloxane à chaîne prolongée est ensuite mis en réaction avec un silane durcissable à l'humidité pour greffer le polyorganosiloxane avec des groupes durcissant à l'humidité. La présente invention concerne également des procédés de formation d'ensembles joints et des procédés de scellement de substrats utilisant les compositions réactives.
