Abstract
The invention relates to a two-component polyurethane composition containing i) 10 to 80 wt. % of at least one polyol with an average molecular weight of 200 g/mol to 3000 g/mol, ii) 5 to 60 wt. % of at least one aromatic polyisocyanate, and iii) 0 to 15 wt. % of an additive. The composition has an NCO:OH ratio of 2:1 to 1:2, and the composition has a viscosity of 20 to 3000 mPas (EN ISO 2555, Brookfield viscometer, 25° C.) and displays a phase incompatibility after the mixing process. The functionality of the polyol mixture is greater than 2.3.
