Medical adhesives for stopping heavy bleeding and sealing leakages

A formulation for staunching the loss of blood (haemostatic) or tissue fluids comprising:

• A) an isocyanate-functional prepolymer obtained from
• A1) an aliphatic isocyanate and
• A2) a polyol component having a number-average molecular weight of greater than or equal to 400 g/mol and an average OH functionality of 2 to 6,
• B) a curing component comprising
• B1) an amino-functional aspartic ester of the general formula (I)
• where
• X is an organic radical obtained by removing the primary amino groups from 1,3-diaminopentane, 1,5-diaminopentane, or 1,13-di-amino-4,7,10-trioxatridecane;
• R1 and R2 are ethyl and
• n is 2;
• B2) optionally, organic fillers which have a viscosity as measured to DIN 53019 at 23° C. in the range from 10 to 6000 mPas,
• and
• C) optionally, reaction products of isocyanate-functional prepolymers as defined for component A) with aspartic esters as per component B1) and/or organic fillers as per component B2).
