CA 2470237

The present invention relates to a one-part room temperature vulcanizable organopolysiloxane rubber composition which crosslinks in the presence of moisture to form a coating for the corrosion protection of metals which is obtained by mixing the following: a) from about 20 to about 60 weight percent of one or more polydiorganosiloxane fluids, b) from 0 to about 40 weight percent of a cycloorganosiloxane, c) from 0 to about 40 weight percent of an inorganic extending or non-reinforcing filler, d) from about 0.5 to about 15 weight percent of an amorphous SiO2 reinforcing filler, e) from about 1 to 7 weight percent of an oximinosilane cross-linkin agent, f) from about 0.2 to about 3 weight percent of an adhesion promoter, g) from about 0.02 to about 3 weight percent of an organotin salt; and h) from about 20 to about 50 weight percent of alumina trihydrate, the alumina trihydrate having a median particle size of 10 ~m to 30 ~m.

L'invention concerne une composition de caoutchouc simple d'organopolysiloxane vulcanisable à température ambiante, qui se réticule en présence de l'humidité pour former un revêtement destiné à protéger les métaux contre la corrosion. Elle est obtenue par le mélangeage de ce qui suit: a) entre environ 20 et environ 60 % en poids d'un ou plusieurs liquides de polydiorganosiloxane; b) entre environ 0 et environ 40 % en poids d'un cycloorganosiloxane; c) entre environ 0 et environ 40 % en poids d'une charge inorganique de dilatation ou sans renforcement; d) entre environ 0,5 et environ 15 % en poids d'une charge de renforcement à base de SiO<sb>2</sb> amorphe; e) entre 1 et 7 % en poids d'un agent de réticulation à base d'oxyminosilane; f) entre environ 0,2 en environ 3 % en poids d'un promoteur d'adhérence; g) entre environ 0,02 et environ 3 % en poids d'un sel organostannique; et h) entre environ 20 et environ 50 % en poids d'un trihydrate d'alumine, le trihydrate d'alumine présentant une taille moyenne des particules entre 10 µm et 30 µm.
