Fumed Silica
HB-
620
Characteristic
FM-H-B620 is hydrophobic fumed silica which is produced by hydrophilic fumed silica with specific
surface area of 200m²/g after chemical post-treatment with HMDS (Hexamethyldisilazane).
Applications | Properties |
● HTV silicone rubber,LSR | ● Reinforcing filler for elastomer |
● Coatings & Printing Ink | ● High hydrophobicity and stable thixotropy |
● Adhesives & sealants | ● Anti-settling and anti-sagging agent in coatings and printing ink |
● Powder Coatings | ● Free flow aid and anti-caking aid for powders |
● Rheological control for adhesives & sealants |
