“The launch of our Alu5 plant is more than just another capacity expansion - it’s a strategic move to bring our high-performance aluminum oxide products closer to our customers in Asia,” said Emmanuel Auer, Head of Evonik’s Smart Effects business line.
Evonik has invested mid-double-digit million Euro for this new production facility in Japan. It will manufacture AEROXIDE, an advanced fumed aluminum oxide solution renowned for its exceptional properties for a variety of applications.
AEROXIDE is tailored for ultra-thin coating technology and does significantly enhance performance and durability for value chains ranging from electric mobility, consumer electronics to sustainable powder coatings. The product not only enhances efficiency and longevity, but also exemplifies sustainability by promoting durable and resource-efficient solutions.
Equipped with the latest production technology, the Alu5 plant sets new standards for quality, efficiency, and environmental responsibility. The results of constructing this facility represent the collaborative efforts between the two Evonik segments –Custom Solutions (including Coating Additives business line) and Advanced Technology (including Smart Effects business line)- underlining the benefit of having both under one roof.
