DB9602 is a fluorine-modified organic silica gel specially used for fuel cell gas circuit sealing. It meets the various environmental requirements of fuel cells. It is suitable for the injection molding of graphite bipolar plates, metal bipolar plates, and MEA. It is cured in the mold to form a sealing strip, which has excellent physical and electrical properties, compression set, and excellent sealing performance.
Typical use： It is suitable for fuel cells, PEM electrolyzers, graphite bipolar plates, metal plate bipolar plates, and membrane electrodes to form a seal by injection
