A process for crosslinking a coating of pressure-sensitive adhesive systems on a backing material, characterized in that

Cross linkage of pressure-sensitive adhesive substances by means of electron beams

Process for producing a rubber-based double-sided pressure-sensitive adhesive tape

Process for the radiation crosslinking of double-sided adhesive tapes, in which a backing material coated on both sides with adhesives is irradiated asymmetrically from both sides with different doses in an irradiation means.

EB and UV crosslinking of composition layers, and products produced with these layers

Multilayer adhesive tape

Use of solid, rubber-soluble or rubber-dispersible monothiols as stabilizers in melted pressure-sensitive adhesive compositions based on natural rubber or synthetic rubbers, suitable tackifying resins and promoters for increasing the radiation crosslinking yield.

Use of monothiols as stabilizers in melted pressure-sensitive adhesive compositions based on natural rubber or synthetic rubbers

The invention relates to a process for the preparation of acrylate-based pressure-sensitive hot-melt adhesives by irradiation on a substrate, characterized in that

Acrylate-based hot-melt pressure-sensitive adhesives

Dressing material of at least one layer of a polymeric, hydrophilic gel and, where relevant, one or more layers of a carrier material as an intermediate and/or covering layer, wherein the gel consists of 40-50% by weight of a polyvinyl alcohol which is crosslinked and acetalized with formaldehyde and is water-insoluble to the extent of at least 90%, 15-30% by weight of water, 15-45% by weight of one or more polyhydric alcohols with 2-6 C atoms and, where relevant, small amounts of additives and/or auxiliaries.

Dressing material based on a hydrogel, and a process for its production

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.
