CURABLE COMPOSITIONS CONTAINING ISOCYANATE FUNCTIONAL COMPONENTS AND HAVING IMPROVED DURABILITY IN THE CURED STATE |
摘要 |
A composition comprising a) one or more isocyanate functional components, one or more oligomers or prepolymers containing isocyanate functional groups and alkoxysilane groups, or prepolymers having a flexible backbone and silane moieties capable of silanol condensation: b) one or more catalysts for the reaction of isocyanate moieties with active hydrogen atom containing groups or for silanol condensation; c) one or more compounds comprising a dihydrocarbyl hydroxy! amine, an alicyclic hydroxyl amine, a nitrile oxide of a dihydrocarbyl hydroxyl amine or a nitrile oxide of an alicyclic hydroxyl amine in a sufficient amount to enhance the ultraviolet stability of the composition in a cured state; and d) a pigment that does not have reinforcing properties or the composition contains one of one or more oligomers or prepolymers containing isocyanate functional groups and alkoxysilane groups, or prepolymers having a flexible backbone and silane moieties capable of silanol condensation. The compositions are useful as adhesives and sealers. |
