Merck opens production facility for liquid crystal window modules
Merck is the world’s first supplier of this technology
Merck, Bart van Overbeeke
Deliveries to start in 2018
“This new facility is a milestone in our strategy to capture new attractive and future-oriented application fields for liquid crystals beyond displays,” emphasized Kai Beckmann, Member of the Executive Board of Merck and CEO Performance Materials, during the inauguration attended by around 100 invited guests from business and politics. “We recently started taking orders from customers for modules that will be ready for delivery as of early 2018. The industry interest in liquid crystal windows we’ve seen so far is very positive.”
Globally, the demand for smart glass is rising. In particular, the construction and automotive industries are looking for long-lived elements that can be integrated both aesthetically and functionally in many shapes and colors. Merck does not see itself as a competitor to glass and window manufacturers, but rather will supply the modules enabling them to make these smart glass elements, windows and façades. In addition, Merck assists architects, designers as well as window and façade makers in an advisory capacity.
For sun protection and privacy applications
In smart glass, liquid crystals regulate light transmission. It serves either as sun or privacy protection. Both variants, which respond within seconds, offer users maximum convenience.
In sun protection applications, exterior blinds and their costly maintenance and repair are unnecessary. The light transmittance of the windows can be lowered down to 5% and set in a continuously variable manner. Energy savings of up to 40% are thus possible with building climate control systems. In both the dark and the bright state, the windows remain transparent and color-neutral and provide an unhindered view outside. Of particular interest to architects is their tremendous flexibility in terms of size and shape as well as the possibilities of their color design with no effect on transparency – a further advantage in addition to switching within seconds – over competing technologies. The privacy variant also switches within seconds from transparent to opaque. It prevents outsiders from being able to look inside conference rooms, restricted production areas or residential buildings.
The liquid crystal materials, which are marketed under the licrivisionTM brand, are also to be used in vehicles in the future. Research is currently underway for further application possibilities, for instance in air and sea travel.
