摘要：
A method for curing a mixture of a matrix and a curing agent based on sulfur-containing polymers on command and so rapidly that a tack-free surface results. A method for coating a substrate with the composition and of curing a sealant is also provided. The matrix and curing agent containing sulfur-containing polymers. The mixture is an uncured mixture with an isocyanate content, and the matrix is uncured and contains a mercaptan-terminated base polymer based on at least one polyether, polythioether, polysulfide or copolymers thereof. The uncured matrix, the curing agent, or both contain at least one photoinitiator based on sterically-inhibited tertiary amines. The mixture cures in the temperature range of −10 to +70° C. after the high-energy actinic radiation is applied. Corresponding matrices A, mixtures B, curing agents, sealant systems, and substrates, e.g., aircraft are contemplated.
摘要（中）：
一种基于含硫聚合物的基质和固化剂的混合物的固化方法，并且如此迅速地使得产生无粘性的表面。 还提供了一种用该组合物涂覆基材并固化密封剂的方法。 含有硫的聚合物的基质和固化剂。 该混合物是具有异氰酸酯含量的未固化的混合物，基质是未固化的，并且基于至少一种聚醚，聚硫醚，多硫化物或其共聚物，含有硫醇封端的基础聚合物。 未固化的基质，固化剂或两者都含有至少一种基于空间抑制的叔胺的光引发剂。 在施加高能量光化辐射后，混合物在-10至+ 70℃的温度范围内固化。 预期相应的矩阵A，混合物B，固化剂，密封剂系统和基底，例如飞行器。
