Curable composition comprises (a) at least one blocked amine comprising a blocked, hydrolytically activatable amino group or at least one reactive group, which comprises hydroxyl-, mercapto- or secondary amino-groups; (b) at least one surface-deactivated polyisocyanate that is solid at room temperature; and (c) optionally water or a water-producing substance. Independent claims are included for bonding of a substrate-S1 with a substrate-S2 comprising either applying the curable composition on the substrates-S1 and -S2, contacting the applied composition together, and heating the applied composition at 60-160 (preferably 90-130)[deg] C, or heating the curable composition at 60-160 (preferably 90-130)[deg] C, applying the heated composition on the substrate-S1, contacting the applied composition with the substrate-S2 within the open time of the composition or applying the heated composition on the substrates-S1 and -S2, and contacting the applying composition together with the open time of the composition, where the substrate-S1 is same or different from -S2 and the time duration between the heating and the application of the composition is few minutes to some days or several weeks. |
