Professional bonding of sandwich panels with RUDERER - Highest quality under roof and wall

Around 20 million square meters of sandwich panels are processed in Germany every year. Sandwich panels are important construction elements in almost all industries. They are used in the automotive, construction, caravan, commercial vehicle, sports and aerospace industries, among others. In addition to roofs, ceilings, facades and walls, these composite panels are used to insulate heating and cooling systems, cabins, refrigerated vehicles, truck bodies, soundproofing and partition walls, vans and tanks. Because sandwich panels have very good insulating properties, they can minimize heat loss and unwanted noise, absorb shocks and even prevent fires. In modern buildings, they help to reduce energy consumption. Depending on the application and requirements, manufacturers use different sandwich constructions. Some focus on thermal insulation, others on sound insulation and weight savings. A robust and load-bearing sandwich construction with a variety of materials and possible combinations is achieved with high-performance adhesives. With the latest bonding technologies from RUDERER KLEBETECHNIK GmbH, sandwich panels of all kinds can be produced in a highly professional, economical and, above all, sustainable manner. The high-performance RUDERER adhesives guarantee maximum strength and absolute design freedom, even for unusual constructions and in series production.

With their high-performance materials, sandwich panels make a significant contribution to fire and noise protection as well as energy efficiency, sustainability and aesthetics. The requirement for sandwich bonding is always the same: a stable, durable composite material must be created from three or more structural components. This usually involves two thin metal cover layers and a core of polyurethane foam or mineral wool. But there are many other composite constructions. Depending on the intended use, insulating, stabilizing, weight-saving, sound-absorbing, environmentally friendly or sustainable materials are used. With the innovative adhesive systems from RUDERER KLEBETECHNIK GmbH, these requirements can be met so that the material mix between the top and core layers has excellent dimensional stability.

In demand: stability, flexibility and durability

Bonding sandwich panels is a constant balancing act between increasing stability and reducing weight, different joining dynamics and temperature expansion coefficients. Sandwich panels, which are used as side walls in vehicles, cabins or truck bodies, have to withstand wind and weather and dynamic loads. Different adhesives are required depending on the area of application and the material used. The outer skin of a sandwich element usually consists of steel and thin sheet in combination with highly cross-linked plastics (duromers) or fiber-reinforced plastics (FRP). To reduce weight (lightweight construction) and improve insulation (e.g. in truck refrigerated boxes), an inner layer often consisting of foamed plastics or insulating materials (e.g. Styropor® or Styrodur®) is bonded between the outer layers.

Managing the material mix: high-performance adhesives

RUDERER KLEBETECHNIK GmbH offers aqueous systems such as dispersions, solvent-based contact adhesives and reactive 1- and 2-component adhesives for bonding sandwich panels. If the sandwich element has a load-bearing function, such as in truck bodies, foaming 1-component PU adhesives such as the technicoll® 8324 PU adhesive are generally used. 1-component adhesives react with moisture from the environment, penetrate the foam material of the core layer, fill the cavities and thus improve the strength of the entire sandwich. Reactive 2-component adhesives such as the high-performance adhesive technicoll® 8301/8302 are better for sandwich elements made of materials that are impermeable to water vapor. This has been used successfully for decades for bonding sandwich panels. Because it does not foam up, it can also be applied in a slightly thicker layer. 2-component adhesives are also used in commercial vehicle bodies, where their vibration-damping effect and ability to equalize temperatures are particularly in demand. In sandwich elements, these properties have the advantage that the core and outer layers remain firmly bonded together despite the loads acting on them. If the sandwich elements are made of materials that are permeable to water vapor, 1-component adhesives have proven their worth. They are usually based on polyurethane (PUR). Contact adhesives have an immediate initial strength and can be used on vertical surfaces, for example.

Solvent-free adhesives for large-area bonding

Both contact adhesives and water-based dispersions are suitable for bonding large surfaces that require immediate initial adhesion. Compared to solvent-based adhesives, dispersions have the advantage of being significantly less harmful to the environment and pose fewer health risks during processing. Solvent-based adhesives have the advantage that they achieve significantly faster initial strength than dispersions. The high-performance adhesives from RUDERER effectively support the function of a sandwich element and provide users with the result in the desired size, thickness and material combination. This ensures the reliable and high-performance production of sandwich panels at all times.

About RUDERER KLEBETECHNIK GMBH

RUDERER KLEBETECHNIK GMBH is your specialist for a wide range of premium industrial adhesives. We are a steadily growing family business in its second generation. Our head office is in Zorneding near Munich. With over 30 years of product and industry expertise in the field of bonding, we can provide our customers from industry and trade with optimum support and assistance with bonding projects - both with the right adhesive products and with the necessary know-how about composites, technologies and applications.

We are distributors and we are manufacturers. This guarantees our customers not only the best technological adhesive solution, but also very high product availability for fast, stable supply chains and the greatest possible flexibility, e.g. in terms of container size or delivery date changes, thanks to our large warehouse.

Our broad and deep range of adhesives includes many premium adhesives from well-known manufacturers such as technicoll, Araldite, Sika, H.B. Fuller, 3M, Panacol, Otto-Chemie, Kömmerling, Weiss-Chemie, Drei Bond, Loctite and Teroson. We select our suppliers carefully and ensure that we only include adhesives of outstanding quality in our portfolio. Access to many different adhesive brands enables us to offer our customers brand-independent advice, always manufacturer-neutral in terms of the best solution for the respective requirement. We can carry out bonding tests for our customers in our technical center in order to determine the right adhesive. This is particularly helpful and useful if the customer does not know the exact properties of the materials to be bonded. We can also carry out ageing tests, climate change tests etc. for our customers and determine tensile shear strength. If our customers have no free capacity in production or lack the bonding expertise, we take care of the bonding projects and carry out the bonding on a contract basis.

With our own brand, the traditional technicoll® brand (www.technicoll.de), we offer a complete range of adhesives for professional applications and, if necessary, modify or develop the right adhesive for individual customer requirements. technicoll® has been well-known on the adhesives market for over 50 years. For decades, we have been successfully supplying the key sectors of industry, such as automotive/transportation/special vehicle construction, the plastics industry, the upholstery industry and the metal industry

As a future-oriented family business in its 2nd generation, we attach great importance to the training and further education of our employees. The focus of our specialized team is always to advise our customers competently with in-depth technical know-how and, if necessary, to support them throughout entire projects.

Our future is digital. We recognized this back in 2007 and launched our online store www.ottozeus.de. There, our customers can find all high-quality adhesive brands, the right accessories, lots of important information and, if required, advice on bonding over the phone - all quickly and reliably, just as you would expect from an online store.
