Abstract: The invention relates to a method for permanently obturating holes, especially in metal sheets or plastic parts of automobile bodies. The inventive method is characterized by using a punched article which is at least partially provided on one side with an adhesive material and includes an especially textile support whose surface is greater than the surface of the hole to be obturated and which is especially provided with a non-expanded expandable body in the center of the adhesive side. The punched article is fixed on the hole together with the support in such a manner that the hole is completely covered by the punched article and the expandable body comes to rest inside the hole. The punched article and the expandable body are heated to such an extent that the expandable body expands, heat is supplied until the expanded expandable body completely fills and/or covers the hole, and the expanded expandable body cools off and cures.

Abstract: The use of an adhesive tape as a bandaging tape for cables, the cables having a PVC-free sheathing including a PVC-free backing to at least one side of which a pressure-sensitive, acrylate-based adhesive composition has been applied, the adhesive tape causing no damage to the sheathing when bonded to the cables at a temperature of at least 100° C. and for a duration of at least 240 h.

Abstract: Self-adhesive lidding film for packaging electronic components, whose adhesive layer is covered with a non-adhesive covering in the center, wherein the adhesive layer comprises a mixture of two acrylate adhesive compositions of different polarity, the first, highly polar component containing from 1 to 20%, in particular from 6 to 10%, especially about 8%, of acrylic acid in the monomer composition, and the other, nonpolar component containing from 5 to 50%, in particular from 10 to 30%, especially about 20%, of stearyl acrylate in the monomer composition, and where an adhesion promoter or primer is present between the adhesive layer and the film support of the lidding film.

Abstract: A visco-elastic gel comprising a high molecular weight polysaccharide, at least one polyol and, optionally, at least one non-volatile acid soluble in the polyol and at least one non-volatile base soluble in the polyol. The polyol has a water content of 5 to 20 percent by weight and the various components set forth are physiologically acceptable. The gel is particularly suitable as a means for releasably securing an electrode to the skin as, for example, when taking an EEG or EKG. Methods of making a suitable electrode and using it are also disclosed.
