Title
(EN) CROSS-LINKABLE MASSES BASED ON SILANE-TERMINATED POLYMERS
(FR) MASSES RÉTICULABLES À BASE DE POLYMÈRES À TERMINAISON SILANE
Abstract
(EN) A crosslinkable substance (M1), which contains (A1) 100 parts by weight of a silane-crosslinked polymer of the following formula: (HO)x-Y-[O-CO-NH-(CR12)b1-SiRa(OR2)3-a] 2-x (I-1), and (B) 600 or more parts by weight of silane cross-linked polymer: R6-O-Z- [O-CO-NH- (CR42)d-SiR3c(OR5)3-c]1-y[OH]y (II). A method of preparing the composition, and the use of the composition as a curable gel product.
(FR) L'invention concerne une substance réticulable (M1), qui contient (A1) 100 parties en poids d'un polymère réticulé par silane de la formule suivante : (HO)x-Y-[O-CO-NH-(CR1 2)b1-SiRa(OR2)3-a]2-x (I-1) et (B) au moins 600 parties en poids de polymère réticulé par silane : R6-O-Z-[O-CO-NH-(CR4 2)d-SiR3 c(OR5)3-c]1-y[OH]y (II). L'invention concerne également un procédé de préparation de la composition et l'utilisation de la composition en tant que produit de type gel durcissable.
