Product Description

Product Description

Hydrophilic silica is used to reinforce and thicken silicone as an anti-slip agent for food and industrial powders, and to thicken non-polar solvents such as xylene, white spirit and styrene.Small particle size, large specific surface area, good thermal stability and low water content. GESEESIL 200 Fumed Silica is a hydrophilic fumed silica with a specific surface area of 200 m2/g. The hydrophilic nature of fumed silica results from the addition of hydroxyl groups to silica atoms directly on the surface of the particle; The hydrophilic fumed silica is now able to bind hydrogen, making it water-dispersible.

Application

1. Paint and coating: as a hexagonal additive, it can effectively prevent pigment filler from settling and layering, improve the weather resistance, scratch resistance, sagging and leveling of the coating
2. Ink, air silicon has good thickening and sedimentation performance, which can adjust the viscosity of ink and prevent pigment sedimentation.
3. Resin, improve numerical thixotropy, make it have good tensile strength, bending resistance, milk, heat resistance and other properties.
4. Chemical fertilizer, plays the role of adsorption, moisture absorption and anti caking in powder fertilizer and suspension and anti sedimentation in liquid fertilizer.
5. Adhesive/ sealant , can be used as thickener and thixotropic agent to increase bonding strength and prevent sagging and collapse during fixed line operation
 

6. Silicone rubber, which can greatly improve its tensile strength and tear strength.
7. Food, gas silicon in powder food can improve fluidity, prevent powder agglomeration and carrier adsorption
8. Medicine, can be used as anti caking agent, drug carrier and excipient of drugs, so as to prolong the efficacy.
9. Toner: improve the fluidity, charge retention and environmental storage stability of toner, and improve the defects such as bottom ash and ghosting during printing.
10. Catalyst carrier: has good adsorption, dispersion and high purity, which can effectively improve the catalyst effect.
11. Optical fiber: gas silicon has excellent thickening thixotropy, which can effectively improve the filling efficiency of optical fiber filling paste
