WEST SYSTEM 406 Colloidal Silica is an off-white epoxy thickening additive supplied in a 5.5 oz (approximately 156 g) pack. Manufacturer part number: 323618.

When used with other fillers, it may help improve the strength, abrasion resistance and consistency of epoxy fairing compounds.

Use in accordance with the applicable WEST SYSTEM mixing, safety and product instructions. Verify suitability for the intended maintenance or repair task before use.
