Fusil 200 is a high-purity Fumed Silica designed for advanced industrial use. Its extremely fine particle structure and large surface area make it ideal for thickening, reinforcing, and improving flow behavior in various formulations.
In adhesives and sealants, it enhances bonding strength and prevents sagging. In coatings and paints, it improves durability, scratch resistance, and prevents pigment settling. For silicone rubber and epoxy systems, Fusil 200 acts as a reinforcing filler that increases tensile strength and elasticity.
Fusil 200 is also used in pharmaceutical, food packaging, plastics, and printing industries as an anti-caking and free-flow agent. Its versatility and consistent quality make it a trusted choice among manufacturers seeking performance and purity.
Avex International ensures every batch of Fusil 200 meets global industrial standards — stored in controlled warehouse conditions to maintain its quality and performance.
