Beschreibung
Zusammenfassung:	A polyurethane composition includes a first component wherein a polyol mixture containing at least one polyol P1 having an average molar mass of 800-30,000 g/mol, the polyol being a polyhydroxy-functional fat and/or oil, or a chemical modification of natural fats and/or oils; preferably at least one polyol selected from the group of polyester polyols and polyether polyols; and a second component wherein at least one aliphatic polyisocyanate I, and at least one filler. The composition includes a tin catalyst for the reaction of hydroxyl and isocyanate groups, forming a thio complexes, and at least one compound including at least one thiol group, wherein the molar ratio of all thiol groups of all metal atoms of the at least one tin catalyst K (T/K) lies between 2.2:1 and 40:1, and the molar ratio of all NCO groups of the at least one tin catalyst K (NCO/K) lies between 50 and 1500.
