摘要：
A polyurethane friable sealing compound free of solvent and plasticizer having a shore A hardness of below 40 and consisting essentially of a polyol component and an isocyanate component. The polyol component is selected from modified triglycerides obtained by partial ring opening of epoxidized triglycerides of a fatty acid mixture containing olefinically unsaturated fatty acids and monohydric or polyhydric alcohols. The isocyanate component is selected from polyfunctional aromatic and aliphatic isocyanates, wherein the OH:NCO equivalent ratio is from 1:0.1 to 1:1.15.
