Beschreibung
Zusammenfassung:	A polyurethane composition includes first and second components, wherein the first component contains between 30% and 99% by weight of a polyol mixture including 100 parts by weight of at least one hydrophobic polyol, 10 to 75 parts by weight of at least one hydrophilic polyol, 0 to 25 parts by weight of at least one diol having two hydroxyl groups linked via a C2 to C9 carbon chain; and also at least one compound having at least one thiol group; and the second component includes at least one polyisocyanate, wherein one of the two components additionally includes at least one metal catalyst for the reaction of hydroxyl groups and isocyanate groups that is able to form thio complexes and the molar ratio of all the thiol groups in the at least one compound to all metal atoms in the at least one metal catalyst is between 1:1 and 250:1.
