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.
