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

The West System 72720 is a 15 oz. non-woven E-glass biaxial fabric tape measuring 4 inches wide by 20 yards long. This high-performance reinforcement material features two layers of fiberglass oriented at ±45 degrees, held together with light stitching for superior strength and conformability.

Key Features:

  • Biaxial construction with flat, non-crimped fibers for reduced print-through and higher stiffness compared to woven fabrics
  • ±45-degree fiber orientation provides excellent shear strength and impact resistance
  • Non-woven construction allows the tape to conform easily to curves and complex shapes
  • Light stitching holds the layers together without adding bulk or weight
  • 15 oz. per square yard weight provides robust reinforcement without excessive thickness

This biaxial glass tape is ideal for structural repairs, tabbing joints, reinforcing high-stress areas, and laminating applications where multidirectional strength is required. The ±45-degree fiber orientation makes it particularly effective for applications requiring torsional stiffness and shear strength. Works with epoxy, polyester, and vinylester resin systems.

Shipped really fast, haven't even had a chance to use the paint yet.

Fast and reliable

AutoPlicity was the only place that had my part very well pleased

Awesome!

The service is great. Wiper refills ordered for my Nissan Leaf did not fit, even though the website listing said they would. I was provided a refund over the phone without having to return the products. So, product listing--1 star; service--5 star
