    摘要: The invention addressed the problem of improving the adhesive strength of a dimensionally stable, soft-rubbing adhesive stick consisting of an aqueous preparation of a synthetic polymer and a soap gel as gel-forming component and, optionally, other auxiliaries. This problem was solved by the use of an at least substantially solvent-free aqueous polyurethane dispersion as the aqueous preparation of a synthetic polymer.

    摘要: The use of esters--liquid at room temperature--of C.sub.6-22 fatty acids with monohydric alcohols and/or of C.sub.6-22 fatty alcohols with monocarboxylic acids as solvents for isocyanates and/or isocyanurates is provided. Because the ester reduces the viscosity of the isocyanates and/or isocyanurates, the mixture will be easy to pump and mix with other components prior to curing. Also provided is a process for reducing the viscosity of isocyanates and isocyanurates comprising adding to said isocyanate or isocyanurate one or more esters selected from the group consisting of C.sub.6-22 fatty acids with monohydric alcohols and C.sub.6-22 fatty alcohols with monocarboxylic acids, said esters being a liquid at room temperature.

    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.
