Hydrocurable compositions are provided containing a plurality of epoxy groups and oxazolidine or oxazine groups which are storage stable for at least one month under anhydrous conditions. This stability is achieved by selecting oxazolidines or oxazines in which the 2-position carbon atom in the ring is free of hydrogen atoms and substituted by alkyl groups or an alkylene group which forms a hydrocarbon ring with that carbon atom. Upon exposure to moisture the oxa-groups ring open for reaction with the epoxy groups. The groups may be in the same or different components and thus the composition may comprise polyepoxide and a compound or polymer containing a plurality of the oxa-groups or a polymer containing both classes of groups. The latter polymer is one embodiment of the invention. The compositions may be used for coating, impregnating and adhesive purposes.
                            本发明提供了含有多个环氧基团和
噁唑烷或噁嗪基团的
水固化组合物,这些组合物在无
水条件下至少可稳定贮存一个月。这种稳定性是通过选择环中 2 位碳原子不含氢原子并被烷基或与该碳原子形成烃环的亚烷基取代的
噁唑烷或噁嗪来实现的。当暴露在
潮湿环境中时,羰基环会打开,与环氧基团发生反应。这些基团可以是相同或不同的组分,因此组合物可以包括聚
环氧化物和含有多个氧杂基团的化合物或聚合物,或含有这两类基团的聚合物。后一种聚合物是本发明的一个实施方案。组合物可用于涂层、浸渍和粘合。
