Innovative bonding on modern paint systems

The DuploCOLL^® NP range - OEM approved and weather resistant

The automotive industry is evolving continuously – new vehicle concepts come along with new materials and new designs. This includes also paint surfaces, which shall not only protect the car body from mechanical and further external influences caused by weather conditions but also give a flawless appearance. Because visual perfection plays a vital role – a perfect finish is key to the important first impression.

Lohmann‘s Bonding Engineers meet these developments with the DuploCOLL^® NP range (NP = New Paint) for exterior applications in the automotive industry.

Anything but superficial

The double-sided PE foam tapes are equipped with a high-performance adhesive which is suitable for permanent bonding on all standard paint and clear coat systems. Plastic exterior components can easily be bonded on coatings with medium and high surface energies.

This specially developed high-performance adhesive features an excellent final adhesion on dirt-repellent paint surfaces and offers an outstanding shear strength. According to standard ageing tests in the automotive industry (heat, humidity, cold, etc.) a constant performance is guaranteed. The entire portfolio was technically checked for clear coat systems of most of the OEM‘s.

The tapes of the DuploCOLL® NP range are an excellent alternative to Acrylic Foam adhesive tapes. The PE carrier foam can compensate for component tolerances better than hard, foamed systems. In addition, they have up to four times less weight.

The compressible, permanently elastic PE carrier foam offers a variety of advantages:

Flexible and elastic
good adjustment to dimensional tolerances
Compensation of different thermal expansions of substrates
Black color makes the tape almost invisible in the application
Good sealing characteristics thanks to the closed cell structure of the foam
Good processability thanks to dimensionally stable construction
The combination of the high-performance NP adhesive with the elastic PE foam carrier allows for an optimal surface wetting.

The DuploCOLL^® 9xxxx NP portfolio at a glance

The DuploCOLL^® 9xxxx NP portfolio consists of adhesive tape solutions in the layer thicknesses 0.50 mm, 0.60 mm, 0.80 mm, 1.1 mm and 1.5 mm. Two liner variants are availabe. The products are equipped with either a white, siliconized paper liner or a yellow, single-sided siliconized PE film liner. Of course, all tapes of the portfolio are also available as rolls, spools or die-cuts in every requested format. To make application processes even more efficient, Lohmann also offers process aids such as mounting films, handling aids or further liner variants for die-cuts.

Exterior add-on parts

Permanent bonding of plastic trim parts to painted surfaces, e.g. side trims, roof trims, sill board covers, kick plates, emblems and letterings, etc..
The NP adhesive on the open side offers a perfect performance on standard plastics of any components
Upon request, assembly aids for the application of emblems and letterings can be provided, too.

The tapes of the DuploCOLL^® NP portfolio offer very good die-cutting propierties thanks to their dimensional stability - so individiual designs even with smallest details and with non-adhesive edges can be realized. They offer a constant performance due to outstanding weather resistance.
