Description

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
