Abrégé
(EN)
Alkoxy-functional one-component RTV silicone rubber composition which is shelf-stable and fast-curing. The composition is formed by reacting a silanol-terminated polysiloxane polymer with an alkoxy-functional cross-linking agent in the presence of a condensation catalyst. The present invention lies in the use of silicon-nitrogen compounds and silicon-nitrogen polymers as scavengers for unendcapped hydroxy groups in the above polyalkoxy-functional RTV systems. A preferred silicon-nitrogen compound is hexamethyldisilazane.

Composition de caoutchouc au silicone RTV alkoxy-fonctionnelle à un composant qui est stable à la conservation et polymérise rapidement. La composition est formée en faisant réagir un polymère de polysiloxane terminé par un silanol avec un agent de réticulation alkoxy-fonctionnel en présence d'un catalyseur de condensation. La présente invention consiste à utiliser des composés de silicium-azote et des polymères de silicium-azote en tant que coprécipitateurs pour des groupes hydroxy non coiffés dans les systèmes RTV polyalkoxy-fonctionnels ci-décrits. Un composé silicium-azote préférentiel est l'hexaméthyldisilazane.
