Connecting of sealing strips

Abstract

A method for connecting sealing strips, includes at least one latent alkyl borane and is substantially free of decomplexing agent for the latent alkyl borane, to a sealing-strip substrate (1), applying a radical-curing adhesive to the sealing-strip substrate (1) pre-treated with the latent alkyl borane, bringing the sealingstrip substrate (1) in contact with a sealing-strip substrate (2) in such a way that the radical-curing adhesive is arranged between the two substrates, and allowing the radical-curing adhesive to cure, a composite structure thus being fonned. The method for adhesively bonding sealing strips based on elastic and thennoplastic substrates, such as EPDM or SBR, but also for adhesively bonding PVC sealing strips. Sealing strips adhesively bonded accordingly are characterized by favorable resistance of the adhesive to alkaline media, wherein conventional adhesives can be used which have optimized properties with regard to the storage stability, the open time, and the curing time thereof.
