Abstract
A polyurethane composition including a first and a second component, wherein the first component is a polyol with an OH functionality in the range from 1.5 to 4 and a mean molecular weight in the range from 250 to 15,000 g/mol, a diol with two hydroxyl groups which are linked via a C2 to C0 carbon chain, and a compound that includes at least one thiol group. One of the two components also additionally contains at least one metal catalyst for the reaction of hydroxyl groups and isocyanate groups which can form thio complexes, and the second component contains enough polyisocyanate that at least 5% by weight of isocyanate groups, in relation to the total polyurethane composition, are contained, and the molar ratio of all thiol groups of the mentioned compound to all metal atoms of the metal catalyst is between 1:1 and 250:1.
