Fumed Silica
HB-
630
Characteristic
FM-H-B630 is hydrophobic fumed silica which is produced by hydrophilic fumed silica with specific surface
area of 400m²/g after chemical post-treatment with HMDS (Hexamethyldisilazane).
Applications | Properties |
● Elastomers,HTV silicone rubber and LSR | ● High reinforcement and transparency in HTV and LSR |
● Coatings & Printing Ink | ● High hydrophobicity and stable thixotropy |
● Defoamer | ● Anti-settling and anti-sagging agent in coatings and printing ink |
● Carbon powder for printer | |
● With large specific surface area, small particle size & good dispersion performance, it enables good defoaming performance | |
● Free flow aid and anti-caking aid for powder |
