PRODUCTION OF SKINS FROM POLYURETHANE DISPERSIONS
A process for producing skins from polyurethane dispersions comprises I. producing on a mold a sheetlike layer of an aqueous dispersion comprising a polyurethane (A), the mold surface being free of any electrolyte which would cause the aqueous dispersion comprising a polyurethane (A) to coagulate, I...

| description | A process for producing skins from polyurethane dispersions comprises I. producing on a mold a sheetlike layer of an aqueous dispersion comprising a polyurethane (A), the mold surface being free of any electrolyte which would cause the aqueous dispersion comprising a polyurethane (A) to coagulate, II. drying the film, produced in step (I), of the aqueous dispersion comprising a polyurethane (A) to obtain a single-layered skin, III. optionally producing a skin composed of a plurality of skin layers by producing on the mold, obtained in step II, coated with a single-layered skin a further sheetlike layer of an aqueous dispersion comprising a polyurethane (A), IV. drying the new film, formed in step (III), of the aqueous dispersion comprising a polyurethane (A) to form a further skin layer, and V. optionally repeating steps (III) and (IV) from 5 to 50 times. |
