Highly pure, pyrogenically produced fumed silica with exceptional surface area and uniform particle morphology.
Optimized for rheology control and thixotropic behavior in demanding liquid systems without compromising transparency.
Excellent dispersibility in both polar and non-polar media, enabling efficient incorporation with minimal energy input.
Low residual sodium and chloride content, supporting stringent requirements in electronics, pharmaceuticals, and high-purity coatings.
Consistent batch-to-batch performance ensured by Evonik’s certified manufacturing and strict quality control protocols.
Thixotropic agents in high-performance silicone sealants and adhesives.
Rheology modifiers in solvent-based and UV-curable industrial coatings.
Anti-settling and anti-sag additives in electronic encapsulants and potting compounds.
Viscosity stabilizers in lithium-ion battery electrolyte formulations and cathode slurries.
Reinforcing filler in specialty elastomers and high-clarity silicone gels.
