Abstract: Housing seals and methods seal off a housing interior from a housing exterior. The housing seals and methods comprise a first elastic adhesive strip and a second elastic adhesive strip, the first and second adhesive strips being arranged between a first housing element and a second housing element. The first adhesive strip comprises a first end portion having a first front side and a first edge face, and a second end portion having a second front side and a second edge face, and is arranged between the first housing element and the second housing element such that the second housing element, with the exception of the application gap, in a closed circulation.

Abstract: 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° C. to 230° 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.

Abstract: Housing seals and methods seal off a housing interior from a housing exterior. The housing seals and methods comprise an elastic adhesive strip that is arranged between a first housing element and a second housing element, wherein the adhesive strip comprises a first end portion having a first edge face, and a second end portion having a second edge face, wherein the adhesive strip and is arranged between the first housing element and the second housing element in such a way that the first and second edge faces lie substantially in a plane, the adhesive strip is arranged between the first housing element and the second housing element in a closed circulation, and the first edge face of the adhesive strip is in contact with the second edge face of the adhesive strip and forms a sealing gap.
