West System Epoxy 406 Colloidal Silica Filler 0.06kg

West System Colloidal Silica is an epoxy thickening additive that controls the viscosity of the mixed epoxy. The strong filler creates a smooth mixture, making it ideal for epoxy bonding and filleting. 406 is West System's most versatile filler and when used with other fillers, can improve strength, abrasion resistance and the consistency of epoxy fairing compounds, resulting in a tougher, smoother surface.
