West System 403 Microfibres are high-quality, light-weight fillers designed for use with epoxy systems in the marine industry. These microfibres improve the strength and bonding characteristics of epoxy, making them ideal for enhancing the durability of repairs and providing excellent adhesion to wood, fiberglass, and metals. They also reduce the brittleness of cured epoxy, allowing for effective control of viscosity during application. Perfect for boat building and repair applications, West System 403 Microfibres ensure a smooth and resilient finish for all your marine projects. Description West System 403 Microfibres are designed specifically for use with WEST SYSTEM Epoxy to enhance its performance in a variety of marine applications. These ultra-fine glass microfibres are effective for thickening epoxy, improving its texture and reducing sagging, making them ideal for vertical applications. By adding 403 Microfibres to epoxy, users can achieve a trowelable consistency that is perfect for filling gaps, creating fillets, and performing structural repairs. The addition of microfibres also contributes to the structural integrity of the cured epoxy, ensuring high tensile and impact strength. These microfibres are particularly beneficial when working on boats, kayaks, and other marine vehicles, as they create a robust bond that withstands harsh marine environments. The increased viscosity helps prevent run-off during application, allowing for precise control in complex repair situations. Additionally, West System 403 Microfibres are compatible with a wide range of WEST SYSTEM Epoxy products, making them a versatile choice for both professional boatbuilders and DIY enthusiasts. For those looking to achieve a durable, long-lasting repair in their marine projects, West System 403 Microfibres serve as an essential additive, providing enhanced strength and ease of use in various conditions.Specification Specification Details Product Name West System 403 Microfibres Type Filler Appearance White powder Mix Ratio Varies depending on application Density Approximately 0.2 g/cm³ Recommended Use Thickening epoxy for filleting and fairing Packaging Various sizes available Shelf Life Indefinite if stored properly
