Single-component moisture-curing composition comprises: at least one polyisocyanate; at least one aldimine compound (I); at least one organomethoxysilane, which contains at least one silicon containing group (VI); and at least one acid, where the ratio between the number of aldimino groups and the isocyanate groups is 0.2-0.8, and the ratio between the number of alkoxy groups of the organomethoxy silane and the isocyanate group is 0.1-0.5. Single-component moisture-curing composition comprises: at least one polyisocyanate; at least one aldimine compound of formula (E1-(N=CH-Y1) n) (I); at least one organomethoxysilane, which contains at least one silicon containing group of formula (-X-CH 2-Si(R8 a)-(OR7) 3 - a) (VI); and at least one acid, where the ratio between the number of aldimino groups and the isocyanate groups is 0.2-0.8, and the ratio between the number of alkoxy groups of the organomethoxy silane and the isocyanate group is 0.1-0.5. E1 : the organic group of an n-valent amine after removal of n primary amino groups; Y1 : monovalent 1-35C-hydrocarbon, which optionally contains an heteroatom; R7 : 1-5C-alkyl, preferably methyl or ethyl; R8 : 1-8C-alkyl, preferably methyl; X : O or substituted oxygen atom; a : 0-2, preferably 0 or 1; and n : 2-4. Independent claims are included for: (1) bonding of a substrate-S1 with a substrate-S2 comprising either applying the composition on the substrate-S1, and contacting the applied composition with the substrate-S2 within the open time of the composition, or applying the composition on the substrate-S1 and on the substrate-S2, and contacting the applied composition together within the open time of the composition; (2) sealing of joints comprising applying the composition between the substrate-S1 and the substrate-S2 so that the composition is made to contact with the substrate-S1 and substrate-S2; (3) an anisotropic composition with a predominant elastic coating and a predominant plastic core obtained by curing the composition by humidity; and (4) isotropic composition obtained by curing the composition by homogeneously mixing in water or homogeneously mixing in water-containing component. |
