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

The West System 40715 Low Density Filler is a blended microballoon-based additive designed for creating lightweight fairing compounds when mixed with epoxy resin. This versatile filler produces smooth, easily workable putties ideal for filling and fairing applications on fiberglass, wood, and composite surfaces.

Key Features:

  • Microballoon-based formula creates easy-to-sand and easy-to-carve fairing putties
  • Excellent strength-to-weight ratio for lightweight repairs and fairings
  • Cures to a distinctive dark red-brown color for easy identification
  • 12 oz container provides ample material for multiple projects
  • Compatible with West System epoxy resins for consistent performance
  • Ideal for boat building, repair, and composite fabrication

Mix this low-density filler with West System epoxy resin to achieve the desired consistency for your application. The resulting mixture is perfect for shaping large radius curves, filling voids, and creating smooth transitions on hulls, decks, and other surfaces. The lightweight nature of the cured mixture makes it especially valuable for applications where weight savings are critical.

Great service and fast shipping. They were the lowest and best price I could find on the internet. Thanks!

Fast&amp; easy checkout, unfortunately no option for faster than ground shipping that I really need for this purchase. I will be vertu impressed if it gets sent out this morning &amp; to me tomorrow

Easy fast thanks

Autoplicity was the cheapest place I could find for my Turbosmart Eboost2. I ordered my controller yesterday and they promptly gave me a receipt and a normal time frame for delivery. Today I got the tracking number and at lunch I got an email saying order complete and delivered. This was an awesome experience and I will definitely be using them next time i'm in the market for a similar product.

Great service

Ordered two items where Autoplicity had the cheapest price and within a few days, it was shipped here as ordered in perfect shape. No hassles at all!

very good

Quick and convenient.

Super easy site to use will come back too.

Customer service was great. FEDEX Freight had damaged my order and they sent another one. I have no complaints and will do buisiness again with Autoplicity.

Great experience. Good service. Reasonable prices.

Had to call technical service for a question. Hold time was very long but once connected the technician was friendly and helpful.

Great price on a hard to find item! Ordered on a Sunday and it shipped the next day via FedEx...so great service!

Easy website to shop on. Good phone support. Package will be arriving in a timely manner. All in all seems like a good company.
