Highly pure amorphous silica with low sodium and chloride content.
Optimized surface chemistry for effective thickening and rheology control in polar systems.
Consistent particle morphology and narrow primary particle size distribution (approx. 13 nm).
Excellent dispersibility in solvents, resins, and aqueous formulations without excessive energy input.
Thixotropic behavior enhances sag resistance and improves storage stability of coatings and sealants.
High-performance silicone rubber compounds for extrusion and molding.
Rheology modifier in solvent-based and UV-curable coatings and inks.
Anti-settling agent in pigmented paints and industrial maintenance coatings.
Reinforcing filler in RTV and HTV silicone elastomers.
Viscosity stabilizer in adhesives and sealants, especially acetoxy and neutral cure types.
