The invention relates to a curable composition containing (A) at least one polyorganosiloxane which comprises at least one hydroxy group bound to a silicon atom, (B) at least one silane of formula (1): Si(R1)m(R2)n(R3)4-(m+n), as defined herein, (C) at least one amino silane, and (D) at least one tin compound, the molar ratio of amino silane to tin compound being 1 : 1 - 50 : 1. The invention also relates to a method for the use thereof. La présente invention concerne une composition durcissable contenant (A) au moins un polyorganosiloxane qui présente au moins un groupe hydroxy relié à un atome de silicium, (B) au moins un silane de formule (1): Si(R1)m(R2)n(R3)4-(m+n) telle que définie dans l'invention, (c) au moins un aminosilane, et (D) au moins un composé d'étain, le rapport molaire de l'aminosilane sur le composé d'étain valant 1 : 1 à 50 : 1. L'invention concerne également la préparation et l'utilisation de cette composition.
