<p>The invention relates to a polyurethane composition for use in aerosol containers, comprising a prepolymer based on toluene diisocyanates (TDI), said compositions having a low content of iscyanate monomer, the content of free monomeric TDI not being more than 0.1 wt%. The composition comprises a TDI prepolymer having a NCO content of greater than 10%. The invention also relates to the use of the polyurethane compositions for the production of one- or two-component adhesives/sealants/foams, or for hot melt adhesives and solvent-less or solvent-containing laminating adhesives, or for assembly foams, potting compounds and rigid, flexible and integral foams.</p> |
