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 13):
A method of bonding a first substrate to a second substrate, comprising the steps of:\n mixing the first and second components of the polyurethane composition as claimed in  claim 1 , applying the mixed polyurethane composition to at least one of the substrate surfaces to be bonded, and joining the two substrates within the open time of the mixed polyurethane composition.
