The adhesive all-rounders for the automotive industry

Lohmann: the development partner and motor for your success

Today, building vehicles is more complex than ever. The reasons are manifold: on one hand the enormous increase in customer demand for quality, design and comfort, on the other, the search for innovative materials, new manufacturing technologies and more efficient processes for manufacturers and suppliers.

Good to know that high-end adhesive solutions make an important contribution and increasingly represent an alternative to screws and clips. Thanks to their enormous flexibility, adhesive bonds adapt perfectly to a wide variation of designs to ensure reliable fixing. In addition, adhesive tapes fulfil many practical supplementary features. Thus vehicles are becoming lighter, virtually vibration-free, and quieter. No wonder that today, an automobile contains on average about 4.5 m² of tape.

What our customers value about Lohmann: With each new adhesive solution, we have the whole process in mind. Which specific requirements are placed on the tape? Is a roll required, an efficient spool or a high-precision die-cut? On which substrates should be bonded? How can we find a particularly efficient solution for automation? These are just some of the questions whose answers are important to us from the outset. We focus on one single goal: to find the perfect adhesive solution for your application.

Design & Function

One of the biggest challenges to the automotive industry is the joining of different materials and surfaces. We face this challenge and accompany you throughout your whole process. Beginning with the requirement analysis via the development and formulation to the finished die-cut part. We ensure the highest quality and efficiency and are always on the cutting edge. Our portfolio covers the bonding of emblems and lettering, kick plates and roof trims, exterior mirrors, decorative parts and trim parts. In this connection, we also offer solutions for various clear coat systems.

	Example: Leather reinforcement - Interior (seats) flexible and strong reinforcement high bi-directional stability does not influence the stitching process low emission Die-cuts in any shapes good adhesion to leather available in black (for dark and coloured leather) and withe (for withe and light coloured leather)
	Example: Pillar cladding (interior) The tape is suitable for deep drawing due to the film liner and the flexible foam carrier Automatic application process possible Cost intensive, subsequent lamination processes are unnecessary High ageing and chemical resistance
	Example: Bonding on glass without pretreatment Direct bonding on glass without activator Save working steps as there is no need of masking and activating the glass before bonding the part The permanently elastic polyethylene foam allows the compensationof linear expansions due to different thermal coefficient of expansion of the substrates The compressible foam carrier is better in compensating component tolerances than hard foamed systems Die-cuts in any shapes available
	Example: Kick Plates Compensates for unevenness (cleavage measure) due to the flexible foam carrier Depending on the bonding without pre-treatment possible (even on plastics) Compensation of different Material expansion coefficients (tension absorption)
	Example: Park Distance Control Sensor (PDC Sensor) Secure bonding possible without pre-treatment Flexible foam carrier compensates for component tolerances Available as customer-specific die-cut
	Beispiel: Bonding exterior mirrors Die-cut parts available in various shapes No interaction between tape and heating system Fulfills Donnelly specification (shatter protection)

Noise Vibration Harshness

It rattles, rumbles, squeaks, creaks, rattles? We have countless sound-reducing materials with which we can precisely outfit your surface self-adhesively. Whether as a roll, coil, sheet, or die-cut part, we can always offer you a customized solution.

	Example: DVD pad Easy assembly by custom-fit positioning of several tape stripes on one liner Exact positioning due to die-cut form Quick processing as only one liner has to be removed No curing times compared to liquid systems Clean application compared to liquid systems
	Example: Cable Fastening. Noise-reducing properties, rattle protection The flexibility of the tapes guarantees an easy covering process of the wiring harness on the headliner especially in curves Effective protection against abrasion of round and flat cables Faster production process compared to hot melt systems (no curing time) No risk of injuries for workers during assembly process compared to hot melt systems
	Example: Single-sided sealing foams Good adhesion to plastic surfaces without pre-treatment Excellent damping properties Excellent sealing properties due to smooth closed cell foam carrier Various foam/adhesive combinations possible (different thicknesses and densities) Die-cuts in any shapes Good processability due to dimensionally stable design
	Example: Combination of expanded polypropylene (EPP) and adhesive tape. Many different combinations of EPP die-cuts and adhesive tapes are realizable Expanded polypropylene has noise dampening properties and high dimensional stability EPP can be die cut in any two dimensional form (limited only by EPP raw material block dimension)

Structural Bonding

For new developments the requirements for adhesive joints are constantly growing. Additionally, a lot of new, innovative materials are used which can't be bonded any longer with mechanical solutions like rivets or screws without destroying the structural integrity of the materials. New surfaces which are dirt-repellent or self-curing are really challenging for adhesives. The reactive adhesive tapes DuploTEC® SBF from Lohmann combine the performance of structural bonding with the ease in handling of a pressure-sensitive adhesive tape.

DuploTEC® SBF are easy to handle, dimensionally accurate, can be applied in advance and can therefore be processed quickly and cleanly.

Automotive Electronics

The automotive sector is one of the leading industries worldwide. Mega-trends (for example, autonomous driving and electric mobility) are, together with factors such as climate change, security and globalization, todays challenges. The electronics in the vehicle thus play a key role in the meantime and must continually become even more compact and lighter in view of the ever-increasing demands on performance and reliability - and this is exactly where the adhesive solutions from Lohmann come into play!

'With our customer-oriented bonding technology, we cover all areas of application of vehicle electronics from:

Power Train & Chassis
