ABSTRACT:
In a method for the production of a sealing and adhesive strip, particularly for the direct glazing of motor vheicles, using a moisture-hardening single-component polyurethane composition based on telechelic isocyanate prepolymers of aromatic diisocyanates in stoichiometric excess and polyols a composition is employed comprising a) a catalyst for the moisture-hardening and b) a blocked activatable cross-linking agent, and a solvent or solvent mixture is continually injected into the inside of the strip during the extrusion of the strip which liberate the cross-linking agent.
For the implementation of the method an extrusion nozzle for the sealing and adhesive strip is used which comprises an injection needle for the solvent opening into the nozzle, the exit opening of which points in the extrusion direction and is located in the region of the center axis of the extrusion die forming the strip.
