Highly pure, pyrogenically produced amorphous silica with exceptional surface area (~200 m²/g).
Provides efficient thickening, anti-settling, and rheology control in low-viscosity systems.
Offers excellent transparency retention in clear coatings and adhesives.
Delivers strong hydrogen-bonding network formation for robust gel structure at low loadings.
Free-flowing, hydrophilic powder with consistent batch-to-batch performance.
Thixotropic agents in solvent-based and high-solids industrial coatings.
Rheology modifiers in reactive adhesives and sealants (e.g., silicones, polyurethanes).
Anti-caking and flow aids in pharmaceutical and nutraceutical dry blends.
Viscosity stabilizers in specialty inks and overprint varnishes.
