Abstract:
A two-component polyurethane composition includes a first component, including at least one polybutadiene polyol P1 having an average molecular weight of 2,000 to 10,000 g/mol and an average OH functionality of 2.1 to 4, and a second component, including at least one polyisocyanate and optionally at least one isocyanate-terminated polyurethane prepolymer. The composition also contains at least one hydrophobic diol P2 having an average molecular weight of 500 to 5,000 g/mol, selected from polybutadiene diols, polyester diols, polycarbonate diols, polyether diols having a repeat unit having at least 4 C atoms, and/or at least one hydrophobic compound P3, which is terminated with amino groups and has an average molecular weight in the range of 200 to 2,000 g/mol. The ratio of the number of hydroxyl groups from P1 to the number of hydroxyl and primary and secondary amino groups from P2 and P3 is 2:1 to 16:1.

Claim (Index 1):
A two-component polyurethane composition comprising\n a first component comprising at least one polybutadiene polyol P1 having an average molecular weight M n  in the range from 2\u2032000 to 10\u2032000 g/mol and an average OH functionality in the range from 2.1 to 4, and a second component comprising at least one polyisocyanate and optionally at least one isocyanate-terminated polyurethane prepolymer, wherein the polyurethane composition further comprises at least one hydrophobic diol P2 having an average molecular weight M n  in the range from 500 to 5\u2032000 g/mol selected from the group consisting of polybutadiene diols, polyester diols, polycarbonate diols and polyether diols having a repeat unit having at least 4 carbon atoms and/or\n at least one hydrophobic compound P3 terminated by amino groups and having an average molecular weight M n  in the range from 200 to 2\u2032000 g/mol,\n where the molar ratio V1 of the number of hydroxyl groups from the polybutadiene polyol P1 to the number of hydroxyl and primary and secondary amino groups from diol P2 and the compound P3 is in the range from 2:1 to 16:1, and where the average molecular weight M n  is determined by gel permeation chromatography against polystyrene as standard.
