Polyurea which can be produced from two polyetheramines and a prepolymer

The invention relates to a polyurea preparable from a) a component A comprising a1) 5 to 40% by weight of at least one polyetheramine 1 (PEA 1), obtainable from at least one polyetherpolyol 1 (PEP 1) and at least one amine 1, where PEP 1 has an equivalent weight of 500, a2) 30 to 90% by weight of at...
