摘要：
Adhesive system comprises: (a) an isocyanate functionalized prepolymer obtained from an aliphatic isocyanate and a polyol with a number average molecular weight of >；= 400 g/mol and an average hydroxyl functionality of 2-6； (b) a hardener component comprising amino functionalized aspartic acid ester (I) and organic fillers exhibiting a viscosity of 10-6000 mPas at 23[deg] C, according to DIN 53019； (c) optionally conversion products of the isocyanate functionalized prepolymer with aspartic acid ester and/or organic filler； and (d) a compound. Adhesive system comprises: (a) an isocyanate functionalized prepolymer obtained from aliphatic isocyanate and polyol with a number average molecular weight of >；= 400 g/mol and an average hydroxyl functionality of 2-6； (b) a hardener component comprising amino functionalized aspartic acid ester of formula (X-(NH-CH(CH 2-COOR 2)-COOR 1) n) (I) and organic fillers exhibiting a viscosity of 10-6000 mPas at 23[deg] C, according to DIN 53019； (c) optionally conversion products of the isocyanate functionalized prepolymer with aspartic acid ester and/or organic filler； and (d) a compound. X : n-valent organic residue, which is obtained by removing primary amino groups of n-valent amine； R 1, R 2organic residue, which exhibits no Zerewitinoff active hydrogen； and n : 2. Independent claims are included for: (1) preparing the adhesive system, comprising mixing the components of (a), (b) and (d) and optionally (c) in a ratio of isocyanate-reactive groups to free isocyanate groups of 1:1.5-1:1； and (2) a two-chamber dosing system comprising the adhesive system, where the chamber comprises the components of (a)-(d). ACTIVITY : Vulnerary. MECHANISM OF ACTION : None given.
