The automotive industry is facing a technological change. As a leading supplier of automotive materials, what kind of innovation can Henkel provide?
The vision for future cars goes something like this: Those cars will be electric and sustainable. At the same time, they will be intelligent, connected and digitally operated. They will even be able to transport passengers to their chosen destination autonomously in an autopilot mode, which will be a safe and comfortable option. Car manufacturers and component suppliers are now working on new concepts and technologies to develop solutions to the number of challenges that this vision poses. Many of these technologies are already being used in series production today, and they are gaining ground rapidly. The automotive industry has actually relied on our technical know-how for many years in this process, because Henkel’s Adhesive Technologies business unit has a unique portfolio – geared towards making cars more sustainable, safer and more comfortable with over 300 different applications.
For example, for years, car manufacturers have been struggling with the increasing weight of vehicles, because of stricter compliances regarding active and passive safety, the multitude of electronic devices and components. The batteries in electric cars all have a tendency to tip the scales. The heavier the vehicle, the shorter its recharge mileage will be. That is the reason why the industry is turning to lightweight construction materials like aluminum or synthetic materials.
Henkel’s adhesives and sealants make lightweight automotive construction possible, because bonding is the new welding. It can support the reduction of a car’s weight by up to 15 percent. Bonded joints can withstand high amounts of stress from oscillations, vibrations and temperature fluctuations, and ensure that different materials remain securely and durably joined together. Among other things, Henkel adhesives are used on car body parts, engines, powertrains, gearboxes, rearview mirrors, seats and steeling wheels. At the same time, they also make cars safer, more resistant to corrosion and more durable.
How and why innovation at Henkel has changed its game?
Henkel has truly global engineering teams, who are working across all areas of automotive mass productionand, who are fully capable of design, project management and launch support for OEM platforms. All regions also have in-house prototyping facilities utilizing 3D printers to provide agile response time in the customers design phase. Regional engineering centers ensure that project teams have direct access to local customer engineering centers. Moreover, global matrix networks ensure that lessons learned from each experience and the best practices are constantly shared among all the regions.
Furthermore, Henkel supports its customers throughout the value chain from the design process to production. For example, Henkel's new NVH & lightweight laboratory is dedicated to noise regulation testing and NVH quality and lightweight improvements, with state-of-the-art experimental and computational analysis facilities. The testing lab that is equipped with modal platform, 3D printer, semi-anechoic room, laser vibrometer, acoustic holography array and full car body oven, can help OEMs and identify the problems and solve them. With global expertise based on extensive experience in the automotive market, we are positioned to provide sustainable, innovative and efficient solutions across the entire value chain. Henkel’s NVH solutions allow the OEMs and automotive suppliers to experiment with ways of damping the noise and reducing weight at the same time to maximize efficacy in all areas involving automotive adhesives.
We learned that Henkel has recently been honored the Technology Innovation Award at IALTA (China) Auto Lightweight Annual Summit 2018. You also mentioned that Henkel’s adhesive business is emphasizing focus on lightweight sectors, what is the reason behind this?
There are many evolving drivers within the automotive industry. However, even with the increasing focus on autonomous and electric vehicles, one key area of focus continues to be bringing down the weight of the car. Reducing the weight by just 10 percent can improve fuel efficiency by six to eight percent.
While high-strength light-weight steel grades continue to be used for reducing the vehicle mass, newer metals with low density, including aluminum and magnesium, are increasingly in demand, as are polymer materials such as fiber reinforced composites.
As a result, modern lightweight designs require new bonding technologies to optimize the material's mix incorporated in today’s vehicle structures. Bonding has a special importance, because it enables the use of combinations of new materials while providing structural advantages for bonded components that enable design flexibility while enhancing vehicle structural integrity.
Henkel is one of the members of International Automotive Lightweight Green Technology Alliance and has been honored with the Technology Innovation Award for two consecutive years. The product selected this year was Henkel Structural Adhesive TEROSON EP Series. It is used in the body shop for metal bonding applications, replacing welding or expensive riveting operations. Application of TEROSON EP Series enables automotive manufacturers to achieve outstanding long-term structural integrity of lightweight materials by optimizing material strength and crash load performance. TEROSON EP Series is a heat curing, solvent free, metal to metal adhesive with good storage stability based on epoxy resins. The material can be spot-welded through and gives maximum strength with curing temperatures between 155 degrees Celsius and 190 degrees Celsius. The product exhibits excellent strength and corrosion resistance at extreme temperatures even after extensive aging and weathering.
In recent years, China's local automotive brands have emerged as a new force in the sectors of new energy vehicles. What’s your strategy in providing services to the local enterprises?
It is a very good question. There are two main reasons which motivate us to develop our adhesive solutions for new energy vehicles. The first reason is that we see a great market potential in China driven by national policy support and consumer preference.
