CA 2560989

The invention relates to a two-component adhesion promoter composition for pre- treating surfaces. Said composition comprises two components: the first component K1 contains at least one hydrolysable adhesion promoter substance A, which is selected from the group comprising organosilicon compounds, organotitanium compounds, organozirconium compounds and mixtures of said compounds; and the second component K2 comprises at least one compound B, which reacts with the adhesion promoter substance A or triggers or catalyses a condensation of the adhesion promoter A. When the packaging is sealed, the first and second components are held in two compartments (1, 2) that are separated by at least one partition (3). The invention also relates to the use of packaging (5) comprising two compartments (1,2) that are separated by a partition and to a pack (6) consisting of packaging (5) and a two-component adhesion promoter composition, which is held in compartments (1, 2) that are separated by a partition (3).

Composition de promoteur d'adhérence à deux constituants pour le prétraitement de surfaces, qui comporte deux constituants, le premier constituant K1 contenant au moins une substance promotrice d'adhérence hydrolysable A choisie dans le groupe constitué par des composés d'organosilicium, des composés d'organotitane, des composés d'organozirconium et des mélanges desdits composés, et le second constituant K2 contenant au moins un composé B qui réagit avec la substance promotrice d'adhérence A ou qui déclenche ou catalyse une condensation de la substance promotrice d'adhérence A. Lorsque l'emballage n'est pas ouvert, les premier et second constituants se trouvent dans deux chambres (1, 2) séparées l'une de l'autre par au moins une paroi de séparation (3). La présente invention concerne en outre l'utilisation d'un emballage (5) à deux chambres (1, 2) séparées l'une de l'autre par une paroi de séparation, et un paquet (6) constitué d'un emballage (5) et d'une composition de promoteur d'adhérence à deux constituants se trouvant dans les chambres (1, 2) séparées l'une de l'autre par une paroi de séparation (3).
