Capping isocyanate prepolymer or polyisocyanate/polyether polyol or polyamine mixture

The invention relates to a polyurethane reactive composition comprising an isocyanate, an isocyanate reactive polymeric compound and a catalyst for the reaction of the isocyanate with the isocyanate reactive compound. The isocyanate reactive compound is a diol or a higher functional polyol of a polyester, of a polyester polyurethane, of a polycarbonate or of a mixture thereof, the polyester being derived from a hydroxy carboxylic acid or from its corresponding lactone, and the catalyst is a sterically hindered bismuth compound.

Polyurethane reactive composition

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&#xb0; 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. The glass module is used for direct glazing of vehicles, especially automobiles.

A method of reinforcing a panel of sheet metal, a shaped plastic body or the like is performed by a one- or multi-layer stiffening member of essentially flat shape which comprises a layer at least partially consisting of a thermosetting resin. Thereby, the stiffening member is subjected to a first heat treatment until at least one of the surfaces of the stiffening member is sticky. Thereafter, the stiffening member is applied to the surface of an element to be reinforced. Finally, the stiffening member is subjected to a second, final heat treatment until all layers comprising a thermosetting resin material are cured. Thus, it is not necessary to manually prepare the stiffening member by removing a protection foil from its sticky surface prior to applying it to the element to be reinforced and fully automated handling is possible.

Method of reinforcing panels

The structural element contains a first sound-absorbing and thermally insulating layer (21) and a second sound-insulating, dimensionally stable supporting layer (23). Preferably, the first layer consists of a thermoformed fibre mat or a foam which is at least partially open-cell, and the second layer consists of a rigid, thermoformed synthetic material, for example a plastic material reinforced with glass fibres. A porous or microporous decorative layer (22) can be applied to the outside of the first layer and a thermoformed carpet (24) can be applied to the outside of the supporting layer. A heat-sealable adhesive layer (27) can be placed between the two layers, the said adhesive layer incrasing the bond between the two layers. Because of the dimensionally stable supporting layer, the structural element can be used as a sound screen without a holding frame or as a sound-insulating bodywork part without a supporting surface, which makes it possible to reduce the weight of the overall construction and to make assembly simpler and cheaper.

The multi-layer body member consists of a support member, e.g. a glass fiber tissue impregnated with a thermosetting resin which is covered by a layer of thermosetting adhesive resin. In order to protect the sticky surface of the adhesive resin, a protection foil made of a meterial shrinking under the influence of heat is provided. The foil comprises slits which open to apertures after a preliminary heat treatment such that an essential portion of the sticky resin surface is freely exposed. Thus, the need to remove the protection foil prior to applying the multi-layer body member to the surface to be reinforced is removed.
