  • Heat-activatable modular structural member, its use and process for the direct glazing of vehicles and adhesive therefor
    Patent number: 6926949
    Abstract: The storable modular component, especially a storable glass module, is prepared for assembly by gluing to another component without using an additional assembly glue. Along its edge it displays a profiled bead of a latent reactive adhesive which includes predominantly one or more polyurethanes with blocked isocyanate groups, or one or more polyurethane preproducts consisting of polyols and/or polyamines and encapsuled polyisocyanates, or one or more polyurethanes with radically polymerizable groups. In this case the reaction of the adhesive can be initiated at an activation temperature of 70 to 180° C. At the same time, it remains tacky and nonflowing but plastically deformable for a time sufficient for assembly. The stated materials are capable of being activated by being supplied with electrical, electromagnetic or magnetic energy or by infrared radiation. The adhesive may contain magnetizable and/or electrically conductive fillers.

    Patent number: 6001204
    Abstract: The storable modular component, especially a storable glass module, is prepared for assembly by gluing to another component without using an additional assembly glue. Along its edge it displays a profiled bead of a latent reactive adhesive which includes predominantly one or more polyurethane preproducts consisting of polyols and/or polyamines and encapsuled polyiscocyantes, or one or more polyurethanes with radically polymerizable groups. In this case the reaction of the adhesive can be initiated at an activation temperature of 70 to 180.degree. C. At the same time, it remains tacky and nonflowing but plastically deformable for a time sufficient for assembly. The stated materials are capable of being activated by being supplied with electrical, electromagnetic or magnetic energy or by infrared radiation. The adhesive may contain magnetized and/or electrically conductive fillers. The glass module is used for direct glazing of vehicles, especially automobiles.
