West Systems 405 Filleting Blend Epoxy Filler

Manufacturer

West Systems

<p>Founded in 1969 by brothers Meade, Joel, and Jan Gougeon in Bay City, Michigan, West System emerged from a shared passion for building sailboats and iceboats. What began as experiments with epoxy technology in the late 1950s evolved into a collaboration with chemists at Dow Chemical Company's epoxy lab, resulting in formulations that could serve as both adhesive and coating. The formulations developed became the basis of the WEST SYSTEM group of products introduced in 1971, revolutionizing wooden boat construction and marine bonding applications.</p><h3>Pioneering Marine Epoxy Technology</h3><p>West System Epoxy was created by Gougeon Brothers—sailors, builders and formulators who know the engineering and chemistry required for high-performance composite structures. In 1970, the brothers launched Adagio, the first large, all epoxy bonded and sealed wooden boat built without the use of fasteners, demonstrating the structural integrity their epoxy formulations could achieve. For over 50 years, WEST SYSTEM epoxy has been the marine industry's trusted brand for versatile, high-quality epoxy resin systems, expanding from marine applications to woodworking, composite construction, and general repair.</p><h3>Comprehensive Product Lineup</h3><p>The company's signature <a href="/7644-west-systems-west-system-products-201176">West System Products</a> include their renowned two-part epoxy systems featuring 105 Epoxy Resin paired with specialized hardeners, fillers, and additives. West System Epoxy is a versatile, high-quality, two-part epoxy easily modified for a wide range of coating and adhesive applications, especially suited for marine applications requiring superior moisture resistance and high strength. The modular system allows users to customize working time, cure characteristics, and physical properties by selecting different hardeners and incorporating various fillers for specific bonding, fairing, or filleting applications.</p><p>Beyond traditional epoxy resins, West System offers specialized solutions like <a href="/7644-west-systems-vinyl-sealant-repair-kit-19328">Vinyl Sealant Repair Kits</a> designed for quick repairs and sealing applications. The brand also provides an extensive selection of <a href="/7644-west-systems-maintenance-parts-accessories-200647">Maintenance Parts & Accessories</a> including metering pumps, mixing pots, application tools, and roller covers specifically engineered for epoxy work.</p><h3>Engineering Excellence and Quality Standards</h3><p>Not all epoxies are created equal—epoxy brands can vary widely in formulations, quality of raw materials, and suitability for marine environments, and it's much more difficult to balance all of the physical and mechanical properties necessary for a versatile, high-quality marine epoxy. West System epoxies are marine-grade and undergo rigorous testing to ensure their strength, making them suitable for applications ranging from boat building and repair to composite construction, woodworking, and structural bonding in demanding environments.</p><p>As an employee-owned, family run organization operating since 1969, West System maintains the same commitment to quality and innovation that drove the Gougeon brothers' original experiments. Their products bond tenaciously to wood, fiberglass, carbon fiber, metals, and many plastics, providing excellent moisture resistance and creating durable, long-lasting repairs and construction that withstand the harshest conditions.</p>

Product Details

West Systems 405 Filleting Blend is a strong, wood-toned epoxy filler designed for creating smooth, professional-quality glue joints and fillets on wooden boat interiors and woodworking projects. This versatile additive blends seamlessly with West System epoxy resins to create a gap-filling adhesive paste ideal for structural bonding.

Key Features:

  • Improved formula mixes easily with epoxy resin for consistent application
  • Consistent brown coloration blends naturally with wood tones
  • Creates smooth, flowing fillets that require minimal sanding
  • Provides excellent structural strength for high-load bonding applications
  • Can be used to modify and adjust the color of other West System fillers
  • Ideal for wooden boat building, marine woodwork, and fine furniture projects

When mixed with epoxy resin, 405 Filleting Blend produces a wood-toned paste with excellent gap-filling and bonding properties. The smooth, easy-to-tool consistency allows for clean filleting work on naturally-finished wooden surfaces where appearance matters. This filler is particularly popular in boat building and marine applications where structural integrity and aesthetic appeal are both important.
