Ambient temperature curing coating composition comprising - a branched alkoxy- functional polysiloxane having the formula R2-O-[Si(R1)2-O]n-R2, wherein each R1 is selected from the group consisting of alkyl, aryl, and alkoxy groups having up to six carbon atoms, and Osi(OR3)3 groups, wherein each R3 independently has the same meaning as R1, each R2 is selected from the group consisting of hydrogen and alkyl and aryl groups having up to six carbon atoms, and wherein n is selected such that the molecular weight of the polysiloxanes is in the range of from 500 to about 2,000, - a catalyst, and - an acrylic polymer. The acrylic polymer is substantially free of functional groups that can react with the polysiloxane or with the catalyst in the coating composition.

L'invention concerne une composition de revêtement durcissant à température ambiante comprenant un polysiloxane à fonction alkoxy ramifié de formule R2-O-[Si(R1)¿2?-O]¿n?-R2, dans laquelle R1 est sélectionné parmi le groupe englobant les groupes alkyle, aryle et alkoxy possédant jusqu'à six atomes de carbone et les groupes OSi(OR3)¿3?, dont chaque R3 possède indépendamment le même signification que R1, dont chaque R2 est sélectionné parmi le groupe englobant des groupes hydrogène, alkyle et aryle possédant jusqu'à 6 atomes de carbone, n étant sélectionné de telle manière que le poids moléculaire des polysiloxanes se situe entre 500 et environ 2 000. Ladite composition renferme aussi un catalyseur et un polymère acrylique. Ledit polymère acrylique est pratiquement exempt de groupes fonctionnels qui peuvent réagir avec le polysiloxane ou avec le catalyseur dans la composition de revêtement.
