WEST System 406 Colloidal Silica

West System 406 Colloidal Silica is a thickening additive used to control the viscosity of the epoxy and prevent epoxy runoff in vertical and overhead joints.

406 is a very strong filler that creates a smooth mixture ideal for general bonding and filleting. It is also our most versatile filler.

West System colloidal silica is often used in combination with other fillers to improve the strength, abrasion resistance, and consistency of fairing compounds, resulting in a tougher smoother surface. Color: off-white.

          Comments about WEST System 406 Colloidal Silica:

          Makes a great filler for bonding wood parts together if used very sparingly in the epoxy. Do not advise opening the tube in a windy place. It is so light that it will blow in the wind like wheat chaff.

            • Blister repair

            Comments about WEST System 406 Colloidal Silica:

            I used this mixed with epoxy resin to repair blisters on my boat. Even though it is extremely fine like talcum powder, it still mixed with the resin well and was easy to work out the clumps to form a consistent paste.

                Great filler. I used it to smooth out the fillet transition in a paddle I built.
