Abstract:
1. A polyurea, obtained by a process comprising reacting a) a component A comprising a1) 5 to 40% by weight of at least one first polyetheramine (PEA 1), obtained by a process comprising reacting at least one first polyetherpolyol (PEP 1) and at least one first amine, wherein the PEP 1 has an equivalent weight of ≦500, and the PEA 1 has a nominal functionality of 2, a2) 30 to 90% by weight of at least one second polyetheramine (PEA 2), obtained by a process comprising reacting at least one second polyetherpolyol (PEP 2) and at least one second amine, wherein the PEP 2 has an equivalent weight of >500, and the PEA 2 has a nominal functionality of 2, and a3) 5 to 30% by weight of at least one aromatic amine chain extender and b) a component B, obtained by a process comprising reacting b1) at least one third polyetherpolyol (PEP 3), where PEP3 has an equivalent weight of >500 and a nominal functionality of 2, and b2) at least one isocyanate wherein the component B is a prepolymer.
