The acquired business develops, manufactures, and sells a broad range of adhesive technologies, primarily serving automotive customers across Asia. It has a leading position in interior assembly bonding and long-standing customer relationships throughout Asia, with sales organizations and manufacturing sites in Japan, China, and Taiwan.
