Key Advantages Provided by Fumed Silica
Enhanced Rheological Properties
Fumed silica acts as a powerful rheology modifier, imparting shear-thinning and thixotropic behaviors. This means products become more fluid when agitated for application and regain viscosity when at rest, crucial for controlled application and preventing drips, which is a key aspect of fumed silica thixotropy.
Improved Stability and Suspension
The ability of fumed silica to form a stable three-dimensional network prevents pigments and fillers from settling. This enhances suspension stability, crucial for maintaining uniform product appearance and performance over time, a common benefit seen in fumed silica for coatings.
Versatile Application Across Industries
From adhesives to sealants and printing inks, the diverse applications of fumed silica are driven by its ability to tailor viscosity and flow. Its effectiveness in both hydrophilic and hydrophobic systems makes it adaptable to various formulation polarities, a key factor in understanding fumed silica particle size effect.
Key Applications
Adhesives and Sealants
Fumed silica provides essential viscosity control, anti-sagging properties, and improved extrudability for adhesives and sealants, contributing to their reliable performance and ease of use.
Paints and Coatings
In paints and coatings, fumed silica enhances rheology, preventing pigment settling and ensuring smooth application and sag resistance, a critical aspect of fumed silica for coatings.
Rubber and Plastics
Fumed silica improves mechanical properties like tensile strength and tear resistance in rubber and plastics, acting as a reinforcing agent and viscosity modifier.
Printing Inks
It ensures optimal viscosity and printability for inks, preventing pigment sedimentation and maintaining consistent ink flow during the printing process.
