The invention relates to a one- or two-component polyurethane system, comprising an SiO2-rich zeolite, especially a SiO2-rich zeolite with a stoichiometric silicium to aluminum ratio of 1.5:1 or more, so that the inventive one- or two-component polyurethane system is suitable for binding any excess or detrimental gases which are produced, especially the carbon dioxide produced during moisture curing of isocyanates or prepolymers containing isocyanates. |
