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.
