Two components coupling composition (I), for surface pretreatment, comprises component (C1) (at least a hydrolyzable coupling substance A comprising organosilicon compound, organotitanium compound and/or organozirconium compounds) and component (C2) (at least a compound B that reacts/catalysts condensation of (A)), where C1 and (C2) are present in unopened condition in two chambers, separated from each other by a partition. Independent claims are also included for: (i) use of a packaging comprising two chambers for storing the two components (C1 and C2) and a partition for separating the two components from each other; (ii) packing comprising the packaging and (I); and (iii) a method for applying (I) for surface pretreatment comprising applying pressure on the partition by applying pressure (which breaks the partition), contacting the two components through an opening (optionally by removing a cover) and applying (I) on the substrate surface. |
