Merck Acquires Liquid Crystal Windows Specialist Peer+

Merck is acquiring Peer+, the Dutch specialist for smart window technology, as of July 1, 2014. The two companies have agreed not to disclose the purchase price.

Merck is pursuing a strategy of leveraging its expertise as the global market leader in liquid crystals in order to develop new fields of application for innovative liquid crystal technology. With the acquisition of its long-standing cooperation partner Peer+, Merck is further advancing the development of the future-oriented market for liquid crystal windows and is bolstering its position as the technology and innovation leader for liquid crystal materials also for applications far from displays.

The major innovation of liquid crystal windows lies in their ability of continuously variable switching from light to dark in just seconds. The optimally controlled light and temperature management can decisively improve the energy efficiency of a building. In addition, the smart windows technology opens up totally new architectural possibilities.

Merck and Peer+ have been cooperating closely since 2011 to develop a market-ready product and production concept for liquid crystal windows. In 2012, the cooperation partners entered into a shareholder agreement under which Merck acquired 70% of the capital interest in Peer+. Merck is now also acquiring the remaining 30%, including approximately 3% from the Eindhoven University of Technology (TU/e), which co-founded Peer+ in 2008 and has been intensively supporting it since then.

In the future, Merck will concentrate the R&D activities of the liquid crystal windows technology at the Peer+ site in Eindhoven, The Netherlands. Merck will not produce the liquid crystal windows itself.

“We see ourselves as an advisor and technology supplier for the industry. We aim to become the leading supplier for liquid crystal materials for the production of smart windows. The liquid crystal technology has proven itself in display applications for decades. It has great potential for revolutionary new applications, such as smart windows, and as the technology leader we want to develop these new markets with strong partners,” said Walter Galinat, head of the Performance Materials division at Merck.

“Together with cooperation partners in the glass and facade technology sector, we want to develop the liquid crystal windows technology ready for mass production. With our expertise and experience in research and development as well as pilot production, we can acquire a pioneering role in the smart windows market and effectively support the industry in integrating this technology into mass production,” added Michael Heckmeier, head of LC Research and Development in the Performance Materials division.

Peer+ has already built an R&D production line for small quantities in Eindhoven.

“In the next step, we are planning together with our partners a pilot line for custom-tailored projects in the premium segment of glass facades. We plan to enter the market with our first pilot projects already in 2015,” said Dr. Casper van Oosten, managing director of Peer+.

Liquid crystal windows basically consist of two panes of glass that are glued together at a distance of a few micrometers. The inward-facing sides of the panes are covered with a transparent, electrically conductive layer (transparent conductive oxide) as well as an orientation layer (polyimides). The gap between the coated substrates is filled with a special liquid crystal mixture. The light transmittance of the window can be controlled by applying a low electrical voltage.

The liquid crystal windows technology developed by Peer+ and Merck (also known so far as Merck Smart Energy Glass Technology (MSEGT)) excels by a number of unique properties: The liquid crystal windows can be switched in just seconds from light to dark and vice versa. Continuously variable dimming and segmented switching are also possible in the future. It will be relatively simple to integrate the technology into all conventional windows. Liquid crystal windows open up totally new possibilities in facade design, for example with very large-surface windows or unusually shaped windows, as well as individual coloring of each single window. The optimally regulated light and temperature management can decisively improve the energy efficiency of a building. Solar cells can be additionally integrated as an option. Liquid crystal windows are extremely durable and also suitable for extreme climate conditions.

Peer+ arose from a research project of the Eindhoven University of Technology (TU/e) in 2008. In close collaboration with the department of Chemical Engineering and Chemistry (research group of Profs. Dick Broer and Albert Schenning) and the Building Physics section as well as Merck, the founders Casper van Oosten and Teun Wagenaar soon succeeded in making Peer+ one of the few specialists worldwide in the smart glass technology sector.
