Powerful bond. Primerless process.

Introducing tesa® ACXplus Primerless Line, our highest performing line of permanent exterior mounting tapes

31 Jul 2018

Bonding of attachment parts to car bodies can be very challenging, parts that need to be bonded to a vehicle have different levels of surface energy. Dissimilar materials like plastics, metal, and glass have different coefficients of thermal expansion, so when they warm up or cool down, they expand and contract at different rates. Acrylic foam based adhesive tapes, thanks to its viscoelastic feature, join materials safely and permanently. For this reason attachment parts like emblems, body side moldings, rocker panels, and fender flares can be securely mounted to exterior car body surfaces and withstand all external influences throughout the vehicle’s lifetime.

Developed for the permanent mounting of LSE and MSE plastic substrates and clear coats

tesa® ACXplus Primerless Line is our high performance tapes for exterior attachment part mounting. Because it is primerless, this double-sided acrylic foam tape delivers a permanent bond from the moment it’s applied – without the need for primer. Applying primer as part of the attachment part mounting process is an expensive, time-consuming, and hazardous process. So if you can eliminate the primer in productionyou can get bottom line benefits from greater process efficiency and a lower total process cost. On top, it can be applied at a wide range of temperature, within the first minute after application our primerless products reach a near-ultimate peel adhesion level on most substrates, whereas the typical solutions on the market need hours to days for achieving ultimate performance. At the same time, the more environmentally friendly production line helps you meet stricter environmental standards and provide healthier working conditions.

tesa® ACXplus 778XX

This triple-layer symmetrically designed double-sided acrylic foam tape was engineered especially for automotive exterior attachment part mounting. Coated on both sides with LSE adhesive, it offers high initial performance on LSE plastics – as well as on difficult-to-bond OEM clear coats. And thanks to its viscoelastic acrylic foam core, tesa® ACXplus 778XX has the ability to absorb and dissipate dynamic and static loads.

Features

  • Viscoelastic acrylic foam core to compensate for different thermal elongation of bonded parts
  • Outstanding wet-out property
  • High humidity and UV resistance

Benefits

Reduce total process time by skipping the primer

Save total cost and improve efficiency

By skipping the primer, our primerless solutions offer a simpler process that help to reduce the total process time and process complexity with tape and part attachment. Using primerless products eliminate quality issues that are related to poor primer application.
Excellent bonding stability at an application temperature as low as 5°C

Robust application over a wide range of temperature

No matter whether it is cold or warm when applying our tapes, within the first minute after application, our primerless products reach a near-ultimate peel-adhesion level on most substrates, whereas the typical solutions on the market need time to set.

Excellent performance within the first minute

Our ACXplus Primerless products is able to reach near ultimate peel adhesion level right after application, even on LSE plastics and difficult-to-bond clear coats without primer.
Achieve healthier and more environmentally friendly production

Achieve healthier and more environmentally friendly production

When the primer process is skipped, we can prevent exposure to hazardous substances. It also help to improve the environment, health and safety issues for your employees who are exposed to primers.
