<h3>About WEST SYSTEM Epoxy</h3><p>Since 1969, <strong>WEST SYSTEM</strong> has been the benchmark for marine-grade epoxy technology. Founded and headquartered in Bay City, Michigan, the brand built its reputation in the demanding world of boat building and boat repair — environments where structural integrity and long-term moisture resistance are non-negotiable. Decades later, WEST SYSTEM remains the go-to choice for professional boatbuilders, marine repair technicians, and dedicated DIYers around the world.</p><p>At the heart of the brand is the legendary <strong>105 System</strong> — a modular, field-proven approach to epoxy that gives users precise control over every aspect of a repair or build. The system centers on WEST SYSTEM Epoxy Products, which pair the 105 Epoxy Resin with a selection of hardeners, each engineered for different working conditions and cure speeds. Whether you need a fast-setting compound for a quick on-the-water fix or a slow-curing formulation for a complex laminating job in warm weather, there is a hardener designed for the task.</p><p><a href="/7644-west-systems-epoxy-adhesives-200378">WEST SYSTEM Epoxy Adhesives</a> take that same foundation and extend it into high-strength structural bonding. These formulations are compatible with wood, fiberglass, Kevlar, carbon fiber, metals, and ceramics — making them equally at home in a marine boatyard, a woodworking shop, or a composite fabrication facility. WEST SYSTEM epoxy forms strong, load-bearing bonds that often exceed the strength of the surrounding material , which is why builders trust it for everything from hull construction to bulkhead installation.</p><p>Rounding out the system, <a href="/200404-fillers-west-systems-7644">WEST SYSTEM Fillers</a> allow users to fine-tune the physical characteristics of a mixed epoxy batch. Users can adjust the epoxy with one of six WEST SYSTEM fillers, or add one of several additives to create specific coating properties. Options range from low-density fairing compounds ideal for creating smooth, sandable surfaces, to high-density microfiber blends engineered for structural glue joints and filleting work.</p><h3>Why WEST SYSTEM Stands Apart</h3><ul style="list-style:disc"><li><strong>Modular versatility:</strong> WEST SYSTEM Epoxy products make up a versatile epoxy system that can be used for everything from basic, long-lasting, marine epoxy repairs to the construction of high-performance composites. </li><li><strong>Moisture resistance:</strong> Designed to create a protective barrier, WEST SYSTEM epoxy prevents water infiltration, ensuring long-term durability in marine environments. </li><li><strong>Broad material compatibility:</strong> WEST SYSTEM marine epoxy is compatible with various materials, including fiberglass, Kevlar, and carbon fiber, for superior structural integrity. </li><li><strong>User-focused design:</strong> WEST SYSTEM 105 Epoxy Resin, Hardeners, Fillers, Additives, and Materials are designed and developed with the end-user in mind. </li></ul><p>Whether you are restoring a classic wooden sailboat, cold-molding a new hull, patching a delaminating deck, or fabricating a custom composite component, WEST SYSTEM provides the engineered materials and the technical guidance to get the job done right the first time.</p>

Product Details

The West System 731 is a versatile 9 oz. fiberglass cloth tape designed specifically for structural reinforcement applications in boat building and repair. This professional-grade tape measures 3 inches wide by 50 yards long and is sold in cases of 4 rolls.

Key Features:

  • 9 oz. per square yard fiberglass cloth construction for optimal strength-to-weight ratio
  • 3-inch width ideal for reinforcing chines, hull-deck joints, and structural corners
  • 50 yard length per roll provides excellent coverage for large projects
  • Designed to bond with WEST SYSTEM epoxy resins for maximum adhesion
  • Provides exceptional tensile strength to resist stress cracking and joint failure
  • Adds abrasion resistance to high-wear areas
  • Conforms easily to curved surfaces and complex geometries

When saturated with WEST SYSTEM epoxy, this fiberglass tape creates a strong, durable composite laminate that reinforces critical joints and stress points. The 9 oz. weight strikes an excellent balance between conformability and structural strength, making it easier to wet out than heavier fabrics while still providing robust reinforcement. Ideal for marine applications including wooden boat construction, fiberglass repairs, composite fabrication, and general structural bonding where additional tensile strength is required.
