Moisture-setting sealant compound with good storage stability and low surface adhesion

摘要

Composition (I) comprises: at least a moisture-reactive group containing polymer (P) comprising a polyurethane polymer (P1), in which the moisture-reactive groups are isocyanate groups and the isocyanate content is 0.1-1 wt.%, a polymer (P2), in which the moisture-reactive groups are silane groups and the content of silane is 0.1-2 wt.%, and a polymer (P3), in which the moisture-reactive groups are isocyanate groups and silane groups and the sum of the content of isocyanate- and silane-groups is 0.1-2 wt.%; and at least an unsaturated natural oil. Composition (I) comprises: at least moisture-reactive groups containing polymer (P) comprising a polyurethane polymer (P1), in which the moisture-reactive groups are isocyanate groups and the isocyanate content is 0.1-1 wt.%, a polymer (P2), in which the moisture-reactive groups are silane groups and the content of silane is 0.1-2 wt.%, and a polymer (P3), in which the moisture-reactive groups are isocyanate groups and silane groups and the sum of the content of isocyanate- and silane-groups is 0.1-2 wt.%, where the content of the isocyanate group is = 1 wt.%, the total content of moisture-reactive groups is = 2 wt.% and the total content of all isocyanate groups is = 1 wt.%; and at least an unsaturated natural oil. An independent claim is included for a cured polymer composition, obtained by reacting (I) with water, preferably in the form of humidity.
