HB- Hydrophobic Fumed Silica HB-630 0 630

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
