摘要:
Adhesive tape strip for a rereleasable adhesive bond, which can be removed from a bonded joint by pulling in the direction of the bond plane, having a nonadhesive grip tab and a subsequent, elongate strip which is adhesive on one or both sides, characterized in that the strip has a width of 2-6 mm and a ratio of width to thickness of less than or equal to 10:1.

Redetachable, self-adhesive device having a plate, the sides and/or front side of which have fastening means, if appropriate, and the rear side of which has a strip of an adhesive film which is adhesive on both sides and is adhesively attached in such a way that one end of the adhesive film protrudes beyond the plate as a grip, the adhesive film being of such a kind that the adhesive bond achieved with it can be released again by pulling in the direction of the bonding plane, stretching the strip, characterized in that the rear side of the plate (1) has laterally alongside the adhesively attached adhesive film (5) spacers (3A, 3B), the height of which is less than the thickness of the adhesive film (5).
摘要:
Adhesive tape for a bond which can be redetached without residue or damage by pulling, having a backing coated on one or both sides with a self-adhesive composition, characterized in that a) a self-adhesive composition whose ratio of tear strength to stripping force (peel strength) at a peel angle of less than 10° to the bond surface is greater than 1.2:1 is applied to at least one of the two sides of the backing, b) the backing has been subjected to controlled pretreatment/damaging in such a way that the detachment force (stripping force) is lower than that of a similar self-adhesive tape with a backing which has not been so pretreated/damaged, and c) the tear strength of the backing is insufficient for redetachment without residue or damage.
摘要:
A heating element including a current conductor through which electric power is conducted and electricity converted into heat by a voltage drop across an ohmic resistor. The heating element is a planar or a strip-shaped structure and is provided with at least one support layer and an adhesive layer, while the current conductor is designed as an additional, current-conducting layer which is arranged between the support layer and the adhesive layer. The support layer, the current-conducting layer, and the adhesive layer are transparent.
摘要:
The invention relates to polyacrylate-based pressure-sensitive adhesives, containing at least one resin and at least one ortho, meta or para-cresol derivative, the aromatic ring thereof being substituted on at least two carbon atoms, wherein the substitutes are derivatives of thiols and/or thioethers. The invention further relates to adhesive tapes comprising at least one layer of said pressure-sensitive adhesive and to the use of said cresol derivatives as an antioxidant for polyacrylate pressure-sensitive adhesives.
摘要:
A pack for adhesive sheets which a) are detachable without residue or destruction by extensive stretching in the direction of their bond plane and b) have on one or both sides a pressure-sensitive adhesive composition based on an elastomer resin mixture, wherein c) the pack is UV-impermeable and d) comprises sheetlike liner materials for the regions of the pressure-sensitive adhesive composition that are to be bonded, and/or an outer packaging for the adhesive sheet, and/or an individual pack with transparent packaging elements.
摘要:
An adhesive tape section having an adhesive region and designed as a polygon having a number of sides and the same number of grip tabs arranged around the adhesive region, or designed as a circle, the adhesive region occupying a central portion of said circle, and a grip tab occupying an outer portion of said circle. The adhesive tape section, when bonded to a substrate, forms a bond with the substrate, which bond is releasible from the substrate by pulling on at least on of said grip tabs in the plane of the bond to stretch the adhesive tape section in the plane of the bond thereby to release the adhesive tape section from the substrate.
摘要:
Use of a piece of adhesive film for bonding a) a plate (6) to an article (5) to be mounted or hung up in such a way that the bond can be separated again without damage and without leaving a residue, by means of b) a double-sided adhesive film (1) having a tab (2) which projects from the adhesive join and which can be pulled in the direction of the bond plane to separate the bond, where c) the plate (6) has a device (7) via which mounting or hanging can take place in a manner known per se, and where d) the bonding is hidden to the viewer of the mounted or hung article (5), if appropriate by the article (5) itself.
摘要:
Core for winding self-adhesively coated materials in web form, wherein the outer contour of the core is formed by at least one substantially round, self-contained segment, the ends of which run together in an edge, with a) the round segment being shaped convexly with respect to the axis of the core, b) the normals to the surface of the round segment being aligned substantially orthogonally with respect to the axis of the core, c) the edge being aligned substantially parallel with respect to the axis of the core and the core having a recess on the inside, so that the roll together with the core can be fitted on commercially available adhesive tape dispensers which have cylindrical core holders.
