HB- Hydrophobic Fumed Silica HB-615 0 615

Characteristic

FM-H-B615 is hydrophobic fumed silica which is produced by hydrophilic fumed silica with specific

surface area of 150m²/g after chemical post-treatment with HMDS (Hexamethyldisilazane).

Applications	Properties
● Elastomers,HTV & RTV silicone rubber,LSR	● Reinforcing filler for elastomer,adhesives & sealants
● Coatings & Printing Ink	● High hydrophobicity and stable thixotropy
● Adhesives & sealants	● Anti-settling and anti-sagging and agent in coatings and printing ink
● Toners
● Powder Coatings	● Improving dispersion and stability of pigment
	● Rheological control for adhesives & sealants
	● Free flow aid and anti-caking aid for powders
