Primary and sealing compounds based on sulfur-containing polymers with a photoinitiator, for curing and method for coating and their use

The invention relates to a method for curing a mixture of resin and hardener based on sulfur-containing polymers, wherein the curing on command and as quickly made that a tack-free surface of the sealant from Aushartungsbeginn in a tack-free time of 0.05 to 5 minutes is achieved and a method of coating a substrate with a mixture of a resin and a hardener for the preparation and curing of a sealant, said sulfur-containing polymers containing the mixture being an uncured mixture having a content of isocyanate, wherein the matrix is uncured and a mercapto-based polymer based on polyethers, polythioethers, polysulfide, their copolymers and / or mixtures thereof containing at which the uncured matrix, the contained curing agent or both of at least one photoinitiator based on sterically hindered tertiary amine, wherein at least one photoinitiator, when inhabitants irken of energy actinic radiation, at least one radical per molecule cleaves on the basis of tertiary amine from which a more active catalyst is formed in particular by H-recording, which can act as a catalyst for curing the sealant, and wherein the mixture from the action of energy actinic radiation in the temperature range from -10 to + 70 ° C hardens, whereby it is referred to as a sealing mass from Aushartungsbeginn. The invention also relates to corresponding base compositions A, B mixtures, hardener and sealants systems and compositions aircraft.
