摘要 <p>Adhesive system comprises: isocyanate functional prepolymer (A) obtained from aliphatic isocyanate and polyol with a number average molecular weight of >= 400 g/mole and an average hydroxyl functionality of 2-6; hardener component (B) comprising aminofunctional asparaginic acid ester compound (B1) and an organic filler (B2) with a viscosity of 10-6000 mPas measured according to DIN 53019 at 23[deg] C; and optionally reaction products (C) of the isocyanate functional prepolymers with the asparaginic acid ester and/or the organic fillers. Adhesive system comprises: isocyanate functional prepolymer (A) obtained from aliphatic isocyanate and polyol with a number average molecular weight of >= 400 g/mole and an average hydroxyl functionality of 2-6; hardener component (B) comprising aminofunctional asparaginic acid ester compound of formula (X-[-NH-CH(-CH 2-COOR 2)-COOR 1] n) (B1) and an organic filler (B2) with a viscosity of 10-6000 mPas measured according to DIN 53019 at 23[deg] C; and optionally reaction products (C) of the isocyanate functional prepolymers with the asparaginic acid ester and/or the organic fillers. X : n-valent organic residue, which is obtained by removing the primary amino groups of n-valent amine; R 1, R 2organic residue, which is free of Zerevitinov active hydrogen; and n : at least 2. Independent claims are included for: (1) producing adhesive systems, comprising mixing the components (A), (B) and optionally (C) in a ratio of isocyanate (NCO)-reactive groups to free-NCO groups of 1:1.5-1:1.1; and (2) a two-chamber dosing system comprising the adhesive system, where one chamber comprises prepolymer component (A), and another chamber comprises hardener component (B) and optionally (C).</p>
