Abstract

The present invention relates to a polyurea system encompassing as component A) isocyanate-functional prepolymers obtainable by reaction of aliphatic isocyanates A1) with polyols A2), which can in particular have a number average molecular weight of ≧400 g/mol and an average OH functionality of 2 to 6, as component B) amino-functional compounds of general formula (I) in which X is an organic residue comprising a tertiary amino function, having no Zerewitinoff active hydrogen, R1 is a CH2—COOR3 residue, in which R3 is an organic residue having no Zerewitinoff active hydrogen, a linear or branched C1 to C4 alkyl residue, a cyclopentyl or cyclohexyl residue or H, R2 is an organic residue having no Zerewitinoff active hydrogen, n is an integer ≧2 or ≦3, in particular for closing, binding, bonding or covering cell tissue, and to a metering system for the polyurea system according to the invention.
