Product Description
406 Colloidal Silica is an epoxy thickening additive used to control the viscosity of the epoxy and prevent epoxy runoff in vertical and overhead joints. This is a very strong filler that creates a smooth mixture, ideal for general epoxy bonding and filleting. It is also West System’s most versatile epoxy filler. Often used in combination with other fillers, 406 can be used to improve strength, abrasion resistance, and consistency of epoxy fairing compounds, resulting in a tougher, smoother surface. It cures to an off-white color.
Adhesive fillers are suitable for most epoxy bonding situations especially with high-density materials like hardwoods and metals. Adhesive filler mixtures cure to a strong, hard-to-sand cured epoxy plastic useful in structural applications like general bonding, filleting and hardware bonding.
