Sika acquires Resonac's adhesives division in Asia. Sika is taking over the adhesives division of Japanese chemical company Resonac Corporation for Asian growth markets. The division develops, produces and sells adhesives primarily for automotive customers in Asia. The transaction is expected to close in mid-2027, as Sika announced on Wednesday. 20.10.2026 22:05 With the acquisition, the construction chemicals manufacturer aims to expand access to key suppliers of Japanese automakers and broaden its offering in vehicle interiors. Under the deal, Sika is taking over three plants in Japan, China and Taiwan. The acquired division is primarily active in bonding interior components for the automotive industry. In Taiwan, the construction chemicals group also expects additional opportunities in the battery solutions business. Sika operates in 103 countries and runs more than 400 factories. Sales in 2025 stood at 11.2 billion Swiss francs. awp-robot/to

Swisspacer and Sika give the glazing edge a new role. What happens when the glazing edge takes on more than its traditional role? With AdheraWindow Technology(TM), Swisspacer and Sika have developed a solution that enables the insulating glass unit to make a greater contribution to the stability of the entire window. This opens up possibilities for larger glass areas, slimmer frames and reduced material usage. The technology has already been tested in collaboration with pilot customers and is on the verge of market launch. In window technology, demands on design, comfort and resource efficiency are growing. Larger glazed areas, slimmer profile profiles and more natural light are in demand. At the same time, material usage and weight need to be reduced without compromising stability and durability. It is crucial not to meet these requirements by introducing ever-greater complexity. Swisspacer and Sika therefore asked themselves a fundamental question: must the necessary stability of the window come primarily from the profile and reinforcement or can the insulating glass unit itself make a greater contribution? - explains Matthias Bach, CEO of Swisspacer. This line of thinking gave rise to the initial concept for AdheraWindow Technology(TM) around the time of glasstec 2022. Four years later, the jointly developed solution is now on the verge of market launch. The basic principle is that Windoorexpert has transferred the structural integrity and rigidity of the entire window - including the sash, frame and its steel reinforcement - directly into the insulating glass unit - says Matthias Hägler, Global Head of Building Components at Sika. The glazing edge as a lever. AdheraWindow Technology(TM) comprises an adhesive from Sika, developed specifically for this application, and a warm edge spacer bar from Swisspacer, also developed specifically for this purpose. The new spacer bar differs in terms of geometry, material composition and surface finish from the existing spacer bars in the Swisspacer portfolio. The key lies in the interaction between the two components: together, they bond the glass panes to form a significantly stiffer insulating glass unit. This opens up new possibilities for window design. Combined expertise for the window technology of tomorrow: the development of AdheraWindow Technology(TM) is based on close collaboration between the teams at Swisspacer and Sika.

Depending on the system, element size and application, the additional rigidity may make it possible to reduce the amount of steel section used in the sash or, in certain configurations, to dispense with it altogether. Less steel and reduced material usage in the frame can lower the element's weight, thereby simplifying transport and installation. Reduced steel usage can also have a positive effect on the U value. Furthermore, the material savings open up potential for reducing the carbon footprint of window production. The design flexibility is not limited to material reduction: the increased rigidity can also allow for larger and taller units with narrower face widths. A change to the profile geometry is not strictly necessary, as the thickness of the glazing unit remains unchanged. Validated in practice. Innovation means more than just making a technical idea work. The key to the success of any new technology is reliable proof of its performance in real-world applications. That is why validation and extensive field testing under actual operating conditions are integral parts of its development process - says Christopher Marjan, Project Leader PPD & Manager Accreditation at Swisspacer. - In this way, Windoorexpert create the foundation and confidence needed to bring AdheraWindow Technology(TM) to market safely and reliably." In addition to internal investigations and tests in accordance with relevant EN standards, the technology was tested in collaboration with pilot partners from various sectors of the value chain. These include the system supplier aluplast, the window manufacturer Bayerwald, and Groke, the manufacturer of aluminium front doors and aluminium loft elements. This collaboration enabled the technology to be assessed from various perspectives - from system design through to the finished window unit and manufacturing processes. With regard to its use in window manufacturing, Matthias Dick, Business Development Manager at Sika, highlights the ability to utilise existing machinery. Window manufacturers can process the technology using the machines they already have in operation. No change to their production is required - says Dick. - Furthermore, one process step can be omitted, thereby simplifying the manufacturing process. Next step: market launch. The jointly developed solution is to be launched on the market as a complete system under the name AdheraWindow Technology(TM) developed by Swisspacer & Sika. The future belongs to solutions that achieve more with less effort and can be easily integrated into existing processes. With AdheraWindow Technology(TM), Windoorexpert aim to help push the boundaries of what is currently possible even further - says Corinna Düring, Head of Marketing at Swisspacer. Joint market launch: The technology is being launched as a complete system under the name "AdheraWindow Technology(TM) developed by Swisspacer & Sika" Companies wishing to explore the technology at an early stage and evaluate potential areas of application are invited to get in touch with Swisspacer and Sika. The upcoming market launch offers the opportunity to familiarise oneself with a new approach to window construction at an early stage and to play an active role in shaping it. 44-100 Gliwice ul.

Sika appoints Till Leisner as communications and IR chief. Sika has appointed Till Leisner as its new head of corporate communications and investor relations. He will take up the position on November 1, 2026, and succeeds Dominik Slappnig, who is stepping down after 16 years at the construction chemicals and adhesives manufacturer. October 12, 2026 09:08 Leisner will be based at the headquarters in Baar and report directly to CEO Thomas Hasler, Sika announced on Monday after the close of trading. He has almost 20 years of experience in investor relations, corporate communications and finance. Most recently, he worked at DKSH as head of investor and media relations as well as sustainability. The departing Slappnig has been with Sika since 2010 and, according to CEO Hasler, has significantly helped shape the company's brand and reputation.
