Product Description

Hydrophobic fumed silica R274 - Silica in toners

Fumed silica can also be used to control the flow of printer ink and control the fluidity of ink to obtain clear printing; it is used as a dispersant and flow control agent in the toning of ink cartridges for copiers and laser printers.
HJSIL R274 is a hydrophobic fumed silica after-treated with Dimethyldichlorosilane (DDS), a kind of Hydrophilic Silica with DDS Treatment.

Silica Performance and Benefits

Higher resolution and enhanced print clarity and color saturation
Perfect flow additive for optimum powder flow
Controlling the electrostatic charging ability of toners
Produces smaller particle size toner for better print quality
Lower raw material and energy costs due to small particle size

Other Applications:
Room temperature vulcanized (RTV), especially electronic potting compounds
Adhesive and Sealants
Inks and Powder Coatings

Product features:
Thickening thixotropic and reinforcing agent
Improves RTV silicone rubber with good shelf life
Improves Rheological control of adhesives
Anti-settling, anti-sagging and thixotropic control of coatings and inks
High free flow and anti-caking of powder coatings
