The present invention provides a flexible two component polyurethane and method for producing the polyurethane. The cured polyurethane is flexible, durable and weather resistant. The polyurethane is suitable for use as a protective layer on various substrates.The flexible polyurethane is the reaction product of solvent-free reaction components. The first component includes one or more polyols, optionally, one or more diols, and a catalyst. The second component includes a primary aliphatic isocyanate crosslinker.
L'invention concerne un polyuréthane souple à deux composants, et un procédé de production dudit polyuréthane. Ce polyuréthane polymérisé est souple, durable et résistant aux intempéries. Il convient pour être utilisé sous forme de couche de protection sur des substrats variés. Le polyuréthane souple est le produit de réaction de composants de réaction sans solvant. Le premier composant comprend un ou plusieurs polyols, éventuellement un ou plusieurs diols, et un catalyseur. Le second composant comprend un agent de réticulation d'isocyanate aliphatique primaire.
