The West 406 Colloidal Silica is the most versatile filler and is a thickening additive for bonding, gap filling and filleting. The addition of this filler controls the viscosity of the epoxy and can be used to prevent epoxy runoff in vertical and overhead joints. When adding colloidal silica in varying amounts to epoxy mix, the viscosity is quickly and easily adjusted. Often used in combination with other fillers, it is used to improve the strength, abrasion resistance, and consistency of fairing compounds, resulting in a harder, smoother surface.
