Abstract
An adhesive is to be provided of which one component can be stored virtually with exclusion of air, in anaerobicform, for a prolonged period, and can thus be introduced into the sleeve of an optical connector in a production operation, and the second component of which can be introduced into the first component with the fiber at the assembly site. This is achieved by an adhesive consisting of at least two components, in which the reaction is initiated by interface contact of the two components. For this purpose the two components each comprise unsaturated compounds which are dissolved in mono- and/or polyfunctional acrylates. One component of the adhesive comprises an organometallic compound and the other component an unsaturated dicarboxylic acid and peroxide. The two components are stable on storage and can be stored for a prolonged period without crosslinking, so that one component can be inserted into a ferrule for an optical plug connection and, as required, the optical waveguide, which can be wetted with the second component, brings about polymerization within minutes by interface reaction when inserted into the ferrule.
