DuPont Announces Strategic Collaboration with YMT to Enhance Riston® Dry Film Photoresist Distribution and Service in Korea

Seoul, KOREA, Sept. 5, 2023 – DuPont Interconnect Solutions (DuPont) today announced that it entered into a strategic collaboration relationship with YMT, a Korean printed circuit board (PCB) materials manufacturer listed on the KOSDAQ exchange. This collaboration combines DuPont’s circuit imaging material expertise and YMT’s local network, which can best address the local customer needs with faster response, better service, and a total solution. Under this collaboration, YMT has invested in establishing a dry film slitting facility in Ansan, Korea, and expects facility operation in October. 

“YMT is one of the leading companies in the global chemical material industry with strong technology development capability. We are pleased to work with YMT to advance the electronic industry and build a more connected value chain to serve our customers in Korea,” said Yuan Yuan Zhou, Global Business Director, Metallization & Imaging, DuPont. Adding the local Riston® dry film photoresist slitting capability will largely accelerate Riston® product delivery and flexibility, heightening Korea’s local customer reach and better service. “We believe the win-win strategy will reinforce our circuit imaging market in Korea while YMT will expand its current product offerings by adding Riston® dry films,” said Zhou.

”We are excited by growing our relationship with DuPont. By aligning more fully with DuPont, we can leverage our strength in technical service and logistics to meet the varied needs of our customers as the industry continues to grow. We are confident that our collaboration will create long-term value for our customers,” said Peter Baek, Chief of Business Officer, Vice President, YMT.
