Abstract

A polyurethane composition for the production of single-component polyurethane foams on dry or wet substrates, wherein the composition is the reaction product of a polyol with a molar excess of difunctional or polyfunctional isocyanates and wherein 10% to 80% by weight of the polyol has been replaced by a nonionic surfactant containing at least one hydroxyl group.
