Prepolymers of polyisocyanates with hydroxy-enamines or hydroxy-ketimines |
摘要 |
Prepolymers having enamine or ketimine groups therein are prepared by reacting a polyisocyanate with a mono-enamine or mono-ketimine having an hydroxy group. The prepolymers may be used as mixtures with further isocyanate, which mixtures harden in the presence of water or atmospheric moisture and are useful as lacquers, casting and patching resins, and for coatings and laminates. |
