FUMED SILICA HB-139

FUMED SILICA HB-139 is a hydrophobic fumed silica with structure modification. It exhibits low thickening effects and excellent processability, allowing for high loading of polymers. Notably, it possesses good antisag properties and exceptional stability in epoxies. In silicone rubber applications, especially at high filler loading levels, it provides excellent reinforcing properties without crepe hardening with aging. This fumed silica is well-suited for transparent systems and offers high water resistance and free-flow aid for powder.
