Abstract

"COMPOSIçãO DE POLIURETANO CONTENDO POLIALDIMINA". A presente invenção refere-se a composições abrangendo pelo menos um pré-polímero de poliuretano A com grupos terminais de isocianato, o qual é preparado a partir de pelo menos um poliisocianato e pelo menos um poliol e de pelo menos uma polialdimina B, a qual é obtenível a partir de pelo menos uma poliamina C com grupos amino primários alifáticos e pelo menos um aldeído D. Além disso, é publicada a preparação dessas composições, bem como a preparação da polialdimina. Adicionalmente, é descrito o emprego dessas composições como adesivo, material de vedação, revestimento ou camada. Além disso, são postos à disposição processos para colar, vedar ou revestir. Finalmente, são descritos artigos, cuja superfície foi contactada pelo menos parcialmente com uma tal composição. A vantagem essencial dessas composições é a falta de odor das composições antes, durante ou após seu endurecimento.
