摘要:
Liner for protecting adhesives with respect to permeates originating from the surroundings or included during winding, stacking or other process steps, having at least one non-stick release layer and at least one getter material that is able to absorb at least one substance capable of permeation, the getter material being contained as a dispersed phase in at least one layer of the liner.
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:
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.
