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.

Thermally vulcanisable adhesive and adhesive strip produced therefrom

A double-sidedly self-adhesive planar element which is intrinsically heatable in a self-regulating way and at the same time has a particularly high flexibility. The planar element has a layer sequence of a posistor heating layer, a contacting layer and an adhesive layer, the contacting layer being a two-dimensional perforate contacting element which within the planar element is therefore present as a contacting element which has not been applied to a backing. Also disclosed is an adhesively bonded assembly of a bonding substrate and a planar element of the aforesaid kind, a method of producing a planar element of the aforesaid kind, and a method of using a planar element of the aforesaid kind for heating an adhesively bonded assembly.

Flexible heated planar element

A double-sidedly bondable planar element which has an electrical contacting layer via which it is self-regulatingly intrinsically heatable and at the same time has a high flexibility. The particular features of this planar element are that the planar element in the storage condition is adhesive on one side only, and is therefore particularly easy to handle, and that, on bonding, the adhesive passes through cutouts in the contacting layer, and the planar element thus becomes double-sidedly bondable. The invention further provides a method for the bonding of this planar element, including as a key step the passage of the adhesive through the cutouts in the contacting layer, thus turning a single-sidedly adhesive planar element into a double-sidedly adhesive planar element.

Heated planar element and method for its attachment

The invention provides a planar element which is intrinsically heatable and which is particularly suitable for attachment to multi-dimensionally curved surfaces. For this purpose the planar element features particularly high deformability, achieved in accordance with the invention through a planar element having a layer sequence comprising a heating layer and a contacting layer, each of these two layers being composed of a polymeric material based on elastomers and/or on plastic polymers which have a particular elongation at break and at the same time a particular tensile elasticity modulus. Furthermore, the invention provides an adhesively bonded assembly comprising a bonding substrate and a planar element of the aforesaid kind, a method of producing a planar element of the aforesaid kind, and the use of such a planar element for heating an adhesively bonded assembly.

The invention relates to a process for producing anisotropic pressure-sensitive adhesives (PSAs) using conventional coating methods. It is envisaged that a PSA film be produced on a transport carrier and that it then be transferred to a further carrier material with simultaneous stretching, the elongation being as least 10%.
