| titleOfInvention | Polyether allophanates stable towards discolouration |
| abstract | A process for preparing polyisocyanate prepolymers containing allophanate structural units that includes reacting a) one or more polyisocyanates with b) one or more polyetherpolyols containing less than or equal to 0.02 milliequivalent of unsaturated end groups per gram of polyol and having a polydispersity of from 1.0 to 1.5 and/or an OH functionality of greater than or equal to 1.9 to provide an NCO-functional polyurethane prepolymer containing urethane groups that are partly or fully allophanatized by further reaction with c) polyisocyanates, which may be different from those from a), and d) catalysts and optionally adding e) acidic additives before, during and/or after the allophanatization. The polyisocyanate prepolymers can be used to produce coatings, adhesive bonds and/or seals. The coatings include one or more of the polyisocyanate prepolymers, and at least one diol or polyol and/or at least one linear and/or cyclic, aliphatic, araliphatic and/or aromatic diamine or polyamine. |
