Highly pure, pyrogenic amorphous silica with exceptional surface area (approximately 180 m²/g).
Optimized for rheology control and anti-settling performance in liquid systems.
Excellent dispersion stability in polar and non-polar media due to controlled surface chemistry.
Low abrasiveness and high chemical inertness, ensuring compatibility with sensitive formulations.
Consistent batch-to-batch quality supported by WACKER’s stringent GMP-aligned manufacturing standards.
Thixotropic agents in high-performance sealants and adhesives.
Reinforcing filler and viscosity modifier in silicone elastomers.
Anti-caking and flow aid in pharmaceutical powders and nutraceuticals.
Stabilizer in industrial coatings and inks requiring long-term suspension.
Free-flow enhancer in specialty pigments and ceramic slurries.
