Wonderful Life with


Top priority of Kolon industries is the happiness of our customers! We will try to be the best in all business fields.

Dry Film Resist


KOLON Industries, Inc. is competing with leading international companies, such as U.S. Dupont, Japan’s Hitachi and Asahi, and now has over 60% market share in the dry film photoresist industry. The company was also the first company to develop dry films and localize them in the market where foreign products were dominant. Its technology became further recognized through the development of ultra-high resolution films, which require the most advanced technology in the industry. The dry film photoresist market is growing with the expansion of the electronics market, including semiconductors and LCDs, and KOLON Industries, Inc.’s Accuimage® is a photosensitive film with a resist thickness ranging from 7 to 75um and is used for multiple purposes, such as PCB, L/F, and packaging. The product has met customers’ needs with excellent properties and is increasing market share with outstanding quality and competitive prices compared with existing foreign products.
