The invention relates to an applicator for die-cut parts (), having a die-cut part strip () with a longitudinal direction (L) having a carrier layer () and an adhesive layer (), where an outer contour of the die-cut parts () is punched through the carrier layer and adhesive layer () down to predetertnined breaking points () and a die-cut part complement () protrudes beyond the die-cut parts () continuously laterally to a longitudinal direction (L), and a punch head () over which the die-cut part strip () runs, where the die-cut parts () running over the punch head () face away from the punch head () by their adhesive layer (), and the die-cut parts () can be pressed by means of the punch head () onto a surface ().

Thermally vulcanisable, meltable adhesives and processes have a meltable polybutadiene-polyurethane, ground sulphur and optionally at least one vulcanisation accelerator, at least one filling material, at least one epoxide resin, at least one tackifier resin, bitumen, at least one softener and further auxiliary and additive materials, wherein said adhesives and processes can be thermally vulcanised within a temperature range of 130&#xb0; C. to 230&#xb0; C., such that same, as well as an adhesive strip produced from same, can be used for adhesion and/or sealing in the automotive industry, as well as in structural work on oiled sheet metal, and in the painting line on e-coated or otherwise painted sheet metal, for example, for crimp fold adhesion, for crimp fold sealing, for seam sealing, for lining adhesion, for hole closure and much more.

Diecuts are configured for permanent closing of holes and have a carrier comprising an assembly of at least two polymeric films. An upper film of the at least two polymeric films has a basis weight of at least 1.0 kg/mand a lower film of the at least two polymeric films consisting of at least two layers, wherein a first layer is in the form of a polymeric film and faces the upper film, and a second layer is in the form of a functional layer with a side of the lower film, facing away from the upper film, bears an applied adhesive composition.

Diecut, in particular for permanently closing holes

A method provides an adhesive strip to protect metal surfaces from corrosion. The adhesive strip has a layer of olefin polymer with a density between 0.86 g/cmand 0.91 g/cmand a crystallite melting point of at least 105&#xb0; C. The adhesive strip is applied onto a metal surface, and the strip is heated such that the layer is molten, thereby forming a corrosion protection layer for the metal surface.

Method for corrosion protection treatment

The in-line repair operations in the automotive industry require high-temperature masking tapes which satisfy a particular profile of requirements. Hence such masking tapes must be temperature-stable and must have a high crosslinking potential. Masking tapes employed are tapes coated with thermally crosslinking natural rubber (NR) adhesives which have a crosslinker resin/phenolic resin component. Thermally reactive pressure-sensitive adhesives of this kind are prepared by a process comprising a non-thermoplastic rubber constituent of the pressure-sensitive adhesive and a crosslinker system, the crosslinker system comprising a promoter component and as crosslinking component a reactive phenolic resin, where, in the process, the rubber constituent and a first component of the crosslinker system are mixed homogeneously in a mixing assembly, at a first processing temperature of the mixing assembly, to give a premix, a premix temperature being established in the premix; subsequently the premix is cooled from the premix temperature to a final composition temperature which is lower than the first premix temperature; and lastly the second component of the crosslinker system is added to the premix.

Process for preparing a thermally reactive pressure-sensitive adhesive

A method for anticorrosive treatment of metal surfaces, especially at edges and transitions of the metal components, characterized in that a self-adhesive tape is applied to the metal surface and the self-adhesive tape contains at least one layer with a material which is heated such that the material melts onto the metal surface and thus forms an anticorrosive layer.
