1.Rheology Control
Fumed silica acts as an excellent rheology modifier in liquid systems. Its three-dimensional network structure provides:
Moisture scavenger in sensitive systems
Carrier for active ingredients
Desiccant in packaging applications
Absorption medium for liquids and vapors
2.Adsorbent
Due to its high surface area, fumed silica serves as:
Preventing settling of pigments and fillers
Maintaining homogeneous dispersion
Stabilizing liquid-solid mixtures
Extending shelf life of formulations
3.Suspension
Fumed silica effectively suspends solid particles by:
Preventing caking and clumping of hygroscopic powders
Reducing interparticle friction
Enhancing powder handling and processing
Maintaining consistent bulk density
4.Free Flow Agent
In powder systems, fumed silica improves flowability by:
Tensile strength and tear resistance in elastomers
Mechanical properties of silicone rubbers
Hardness and durability of composite materials
Dimensional stability in cured systems
5.Reinforcement
As a reinforcing filler, fumed silica significantly enhances:
Thixotropic behavior (shear-thinning characteristics)
Anti-sag properties for vertical applications
Improved application properties in coatings, adhesives and sealants
Controlled viscosity stability over time
