World's First Encapsulated Iron Catalyst for Silicone Curing Enhances Air Stability

NEDO, Kitasato University, and Fuji Polymer Industries have developed a groundbreaking technology to encapsulate iron catalysts using silicone resin. This innovation improves air resistance by over 10,000 times, enabling long-term stability for over a year. The technology has been validated in the mass production of Silicone Thermal Interface Materials (TIM) using existing equipment designed for platinum catalysts. This breakthrough aims to reduce dependency on rare metals like platinum and build a sustainable silicone industry base.
