WEST SYSTEM 406-2 Fiberglass & Repair 406 Colloidal Silica is a premium thickening additive used to control the viscosity of epoxy and prevent runoff in vertical and overhead joints. This 1.7 oz container is perfect for smaller projects, repairs, and users who want to try this very strong filler before committing to larger quantities. Prevents Runoff on Vertical Surfaces: When mixed with epoxy, Colloidal Silica thickens the mixture to a consistency that stays in place on vertical and overhead surfaces without sagging or running. This makes it essential for bonding and filleting applications where gravity would otherwise cause unthickened epoxy to flow away from the joint. Very Strong Filler: 406 is one of the strongest fillers in the WEST SYSTEM line, creating high-strength bonds and structural fillets that can withstand significant loads. The fine particle size creates a smooth, workable mixture that's ideal for general bonding, filleting, and applications requiring maximum strength. Smooth, Workable Consistency: Unlike some fillers that create gritty or difficult-to-work mixtures, Colloidal Silica produces a smooth, creamy consistency that's easy to apply and tool into professional-looking fillets and joints. The smooth texture also makes it easier to fair and finish after cure. Versatile Filler Applications: Beyond standalone use, 406 is often combined with other fillers to improve their properties. When added to fairing compounds, it improves strength, abrasion resistance, and consistency, resulting in a tougher, smoother surface that's easier to sand and finish. Key Benefits: Prevents Runoff: Thickens epoxy for vertical and overhead applications Very Strong: Creates high-strength structural bonds and fillets Smooth Mixture: Easy to apply and tool into professional fillets Versatile: Use alone or combine with other fillers Improves Fairing: Adds strength and smoothness to fairing compounds Off-White Color: Neutral appearance for various applications Common Applications: General bonding and structural filleting Vertical and overhead joint bonding High-strength adhesive applications Improving fairing compound properties Creating smooth, strong fillets and joints Smaller repairs and projects Mixing Guidelines: Add Colloidal Silica to mixed epoxy resin and hardener gradually while stirring until you achieve the desired consistency. For bonding and filleting, mix to a peanut butter-like consistency that holds its shape without sagging. For thinner applications, use less filler. This 1.7 oz container is ideal for smaller bonding and filleting projects or for users who want to experience the very strong, smooth-working properties of Colloidal Silica before purchasing larger quantities.
