    Abstract: The invention relates to a polyurea system comprising as component A) isocyanate-functional prepolymers which can be obtained by reacting aliphatic isocyanates A1) with polyols A2) that can have a number-average molecular weight of =400 g/mol and an average OH functionality of 2 to 6 in particular; and as component B) amino-functional aspartic acid esters of the general formula (I) in which X is an organic group containing a secondary amino function, R1, R2 are the same or different organic groups that do not have Zerewitinoff-active hydrogen, and n is a whole number of at least 2, in particular for sealing, bonding, gluing, or covering cell tissue. The invention also relates to a metering system for the polyurea system according to the invention.
