    摘要： Solvent-containing formulations including NCO-containing prepolymers based on TDI isocyanurate polyisocyanates and diphenylmethane diisocyanates where some prepolymers are prepared using a polyetherdiol containing ethylene oxide blocks and having an ethylene oxide content of from 2 to 18% by weight, based on all the alkylene oxide units. The formulation have an NCO content of 1% to 7% by weight, a solids content of 20% to 70% by weight, a monomeric TDI content of less than 0.2% by weight and a monomeric methylenediphenyl diisocyanate content of less than 2% by weight. The solvent-containing formulations can be prepared in organic solvents by reacting at least one of A) a TDI component comprising TDI isocyanurate polyisocyanates and B) an MDI component comprising diphenylmethane diisocyanates with C) a polyetherdiol. The solvent-containing formulations can be used in moisture-curing coating compositions, adhesive bonds and/or seals with substrates.

    摘要： The invention relates to a method for producing flat, hydrophilic, aliphatic polyurethane foams. The invention also relates to a flat, hydrophilic, aliphatic polyurethane foam obtained according to said method and to the use thereof as a wound dressing, incontinence product or cosmetic article. According to the invention, a prepolymer-component and a carbonic acid or carboxylate component containing water is produced, said components are combined and mixed, and the obtained mixture is applied to a flat substrate as a layer which has an even thickness. Directly after application, a perforated separation element is applied in a flat manner to the layer. Said applied layer then expands with the applied perforated separation element to form the flat polyurethane foam.
