Characteristic

FM-H-B139 is hydrophobic fumed silica which is produced by hydrophilic fumed silica with specific surface area of 200m²/g after chemical post-treatment with PDMS (Polydimethylsiloxane).

Applications	Properties
● silicone rubber	● Good thickening and thixotropic property
● Coating & printing ink	● Good anti-sagging properties and excellent stability in epoxy resin
● Adhesives & sealants	● Excellent reinforcing properties in silicone rubber especially at high filler loading levels and no crepe hardening on aging
● Greased & cable gel
● Unsaturated resin	● Well suited for transparent systems
● Powders coating	● High hydrophobicity,free flow aid for powder coatings
