Elevate your marine projects with West System 406 Colloidal Silica. Description West System 406 Colloidal Silica is a versatile and essential thickening agent specifically formulated for use in marine epoxy applications. This fine, white powder is designed to be mixed with West System epoxy resin to create a low-viscosity adhesive that can be easily applied in various marine environments. Key features include its high filler content, enabling it to create a gel-like consistency that prevents sagging during application, making it ideal for vertical or overhead repairs. West System 406 enhances the bonding strength of epoxy by increasing its viscosity without sacrificing workability, ensuring that epoxy adheres effectively to metal, wood, fiberglass, and other materials commonly used in marine construction and maintenance. Typical use cases for West System 406 Colloidal Silica include bonding, filleting, and fairing marine structures, as well as sealing joints and repairs where added thickness is necessary. The added silica also increases the thixotropic properties of the epoxy, helping it to resist dripping and running, which is critical in retaining a clean working area. Practical benefits for marine users include improved control during applications, resulting in more precise fillet shapes and smoother fairing. The product’s chemical compatibility with West System epoxy ensures optimal performance, delivering long-lasting, water-resistant bonds that withstand the harsh marine environment. For those involved in boat building, repair, or maintenance, West System 406 Colloidal Silica is a reliable choice that enhances the performance and durability of epoxy applications, ultimately leading to better quality workmanship and increased longevity of marine vessels.Specification Specification Details Product Name West System 406 Colloidal Silica Type Thickening Agent Appearance White Powder Weight 1 lb (0.45 kg) Mix Ratio Up to 15% by weight Viscosity Increases viscosity of epoxy Applications Filling, fairing, and bonding Storage Cool, dry place Shelf Life Indefinite when stored properly
