| 摘要 |
The present invention discloses a two-component adhesion-promoter composition for surface pretreatment, comprising two components, the first component, K 1 , comprising at least one hydrolyzable adhesion promoter substance A which is selected from the group comprising organosilicon compounds, organotitanium compounds, organozirconium compounds, and mixtures thereof; and the second component, K 2 , comprising at least one compound B which reacts with the adhesion promoter substance A or triggers or catalyzes condensation of the adhesion promoter substance A, and the first and the second components in the unopened state being present in two compartments ( 1, 2 ) separated from one another by at least one dividing wall ( 3 ). Additionally disclosed are the use of a pack ( 5 ) having two compartments ( 1, 2 ) which are separated from one another by a dividing wall, and a package ( 6 ) composed of a pack ( 5 ) and of a two-component adhesion promoter composition, in the compartments ( 1, 2 ) separated from one another by a dividing wall 3.
