        WEST SYSTEM® 406 Colloidal Silica Adhesive Filler is a premium epoxy thickening additive designed to produce strong, moisture-resistant structural adhesives and smooth, durable fillets. Made from fumed silica, this white powder blends easily with WEST SYSTEM 105 Epoxy Resin and compatible hardeners to create a non-sagging epoxy mixture that remains easy to apply on vertical and overhead surfaces while delivering exceptional bonding performance.

        As one of the most widely used general-purpose adhesive fillers in the WEST SYSTEM product line, 406 Colloidal Silica significantly increases the strength, toughness, and water resistance of cured epoxy. It is ideal for structural bonding, gap filling, filleting, laminating, and reinforcing joints in wood, fiberglass, composites, and many other materials. It can also be blended with other WEST SYSTEM fillers to modify handling characteristics, sanding properties, or finished appearance for specialized applications.

        Compatible with WEST SYSTEM 105 Epoxy Resin, 200 Series Hardeners, G/flex® 650, and G/5® Five-Minute Adhesive, 406 Colloidal Silica is trusted by professional boat builders, repair technicians, woodworkers, and composite fabricators for demanding marine and industrial projects.
