Kitasato University and Fuji Polymer Develop Air-Stable Iron Catalyst for Silicone Curing
Kitasato University and Fuji Polymer Industries have created an iron catalyst for silicone curing that offers over 10,000 times improved air resistance compared to previous variants. This innovation supports cost-effective mass production alternatives to platinum catalysts, addressing industry demand for lower-cost, high-performance materials.

Kitasato University and Fuji Polymer Industries have developed a silicon resin technology that significantly enhances air stability of iron catalysts for silicone curing. This encapsulation technology allows production of silicone thermal interface materials (TIMs) under existing platinum catalyst equipment without new capital investment.
Catalyst performance was improved to maintain effectiveness for over one year at room temperature, contrasting sharply with earlier models that degraded within 30 minutes of air exposure. The initiative, supported by Japan's NEDO, aims to reduce reliance on rare metals and could lower manufacturing costs in the materials sector, facilitating broader deployment of iron-based catalysts.
