TAPES + ADHESIVES Tape technology for the automotive industry
High strength permanent adhesives are becoming increasingly important in the automotive industry. As a manufacturer of self-adhesive system solutions and a long-term partner for the sector, tesa says it knows the industry’s needs and now offers especially high performance tapes with its innovative tesa®
ACXplus product line. t
esa points out that due to their balanced material behaviour, tailored layer thicknesses, flexible design and extreme durability, double-sided adhesive tapes on an acrylate base are suitable for many kinds of applications. The tesa®
ACXplus Black Line tapes securely mount attachment parts to the car body and at the same time provide
reliable sealing and vibration damping. The tapes also compensate for thermal expansion and ensure excellent stress dissipation. The products are deep black, and their high level of conformability allows for application in curves and corners. tesa highlights that the innovative and
environmentally friendly acrylate adhesive tapes show off their strengths ideally in permanent adhesive bonds which needs to withstand all external influences throughout the vehicle lifetime. Among other things, emblems, body side moldings, window frames, spoilers, parking distance sensors, as well as decorative trims can be bonded with the new tesa®
ACXplus Black
Line. In addition, the stress-dissipating adhesive tape products compensate optimally for material expansion relating to thermal dynamics and ensure tension free bonds. Also, their special layer thickness protect against undesirable vibrations.
Lohmann launches innovative adhesive film
As bonding is now one of the topics of the future in practically every area of industry, Lohmann GmbH & Co KG has launched its new adhesive all-rounder which can be used in a variety of industries.
A
heat activated adhesive film, it develops extremely high adhesive strength and is classified as ‘Superior Bonding Film’ (SBF). SBF is a polyurethane based hot melt adhesive that is activated by heat and pressure. When activated at 100˚C, the strong
bonding properties of the film develop after as little as ten seconds. Protracted curing times, which might last up to a day with other bonding methods, are eliminated and the user saves valuable production time. Once cured, the bond is irreversible and up to 1,000 times stronger

than other adhesive tapes. Production processes can be optimised by pre-laminating the bond. This involves heating the adhesive film to approximately 60˚C, causing it to start bonding lightly to the substrate. Materials can thus be pre-laminated up to a week before they are actually required on the production line, where the final bonding then takes place. Films in the DuploTEC SBF range are available as die-cut
parts or on rolls in thicknesses between 15µm and 100µm. The film exhibits a fine lined pattern and constant thickness without any sporadic variations. The semi-structural adhesive film can therefore be used in a variety of applications in fields such as automotive, consumer goods, the textile industry, mobile communications and the electronics sector. The advantages of the new semi-structural adhesive film
from the DuploTEC range are being demonstrated at the Hannover Fair in the special Adhesive Technology area in Hall 5, Stand E13. Also at the show applications using DuploTEC SBF are being presented in conjunction with Maschinenfabrik Herbert Meyer GmbH, a specialist in hot-laminating equipment and hot presses, on Stand D22. These applications include technical textiles being bonded on Meyer hot-laminating equipment using the Lohmann semi-structural adhesive film.
