Adhesive tapes for masking and protective measures in the painting and plastering trade are not subject to any standardization. It is different with the standardized tapes for the packaging industry or for applications in electrical engineering.
For years and days, adhesive tapes have served as versatile helpers on construction sites and in the private sector. They are used on coated surfaces of furniture or wall surfaces for photos, posters or posters or as part of masking work. When the surface is later removed, it is often damaged or the paint coating is detached from the wall surface or cladding.
In the production of the tapes - depending on the application requirements and the adhesive used - the backing materials are also subjected to a chemical or physical pretreatment so that an adhesive performance that is precisely adapted to the respective purpose can be achieved. Special adhesive tapes are available for many areas of application. B. very tear-resistant, hand-tearable, very thin, UV-resistant, aging-resistant, abrasion-resistant, flexible, writable and can be removed without residue. Clean, firm and stable surfaces that must be free of dust, oil, grease and moisture are prerequisites for good adhesive contact. A sufficient gap strength is important for wooden surfaces, this avoids fiber tearing.
However, the unknown interaction of the adhesive layer with the coated substrate as well as the behavior of the adhesive force with aging are incalculable. After a long time, cross-linking reactions in and with the adhesive and the substrate cannot be excluded. This sometimes results in an extreme increase in adhesive strength. If the bond can still be removed without damage, discolouration in the area of the contact surfaces is possible or the coating softens due to migration of plasticizer.
An exception are certain painted surfaces, especially reaction resin or stove enamels. Such coatings generally show little tendency to interact with the adhesives. Paintings on which adhesive tape can be used must therefore be checked for load-bearing capacity and strength, e.g. B. by scratch test, cross cut test or tape test.
When removing tapes, it is recommended to do so at a steady pace and at an angle between 30 and
Remove the tapes from the surface 45 degrees. They should always be subject to the intended use. Pay attention to the purpose specified by the manufacturer.
For the first time, the flexible FlexTack adhesive base from HellermannTyton offers a real alternative to screw fastenings for cables and wires on curved and angled surfaces
With the newly developed in-line valve series PVL-B2, Parker Hannifin offers a solution that, thanks to its consistent design principle, can be used in a variety of ways in almost all machine configurations, both as a single valve on an insulated cylinder and as well blockable valve for entire cylinder groups
The drive specialist Menzel can process urgent custom-made products such as on short notice and reliably. The latest example: A replacement drive for a no longer available Siemens motor keeps the compressor in operation in a Swedish paper mill
Constant further development of the adhesive tapes is important. They are proud of the "orange" and the "blue" painter's tape, both produced in Europe
