High-purity, surface-treated fumed silica offering excellent dispersion stability in non-aqueous systems.
Designed to deliver consistent rheology control and anti-settling performance in demanding formulations.
Low abrasivity and low dust generation for improved operator safety and handling efficiency.
Thermally stable up to 200 °C, supporting high-temperature processing and curing applications.
Compatible with a broad range of silicone polymers, resins, and organic solvents.
High-performance silicone sealants and adhesives requiring thixotropic structure.
Electrically insulating encapsulants and potting compounds for power electronics.
Thermal interface materials (TIMs) where controlled viscosity and long-term stability are critical.
Flame-retardant silicone elastomers used in wire & cable and transportation components.
Specialty coatings and protective films requiring sag resistance and uniform film formation.
