Abstract
The present invention relates to a polyurea system, the use of such a polyurea system for sealing, linking, gluing, or covering of cellular tissue, and a dosing system having two chambers for a polyurea system such as this. The polyurea system comprises as components: A) an isocyanate-functioning prepolymer, which can be derived by reacting aliphatic isocyanates with polyoles, and B) an amino-functioning ester of aspartic acid. According to the invention, water and/or tertiary amine is added to the system, in order to increase the reacting speed of the prepolymer with the amino-functioning ester of aspartic acid while decreasing the setting time at the same time.
