West System 105A Epoxy Resin - 1 Quart

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 105A Epoxy Resin is a clear, light amber, low-viscosity liquid epoxy resin specifically designed to wet out and bond with wood fiber, fiberglass, reinforcing fabrics, and a variety of metals. This Group Size A container holds 1 quart (4.3 pints) of resin and must be paired with an A-size container of West System hardener (205, 206, 207, or 209) sold separately.

Key Features:

  • Cures in a wide temperature range to form a high-strength solid bond with excellent moisture resistance
  • Formulated without volatile solvents, does not shrink after curing, and has a relatively high flash point with no strong solvent odor
  • Possesses excellent thin-film characteristics including superior flow out and the ability to self-level without fish-eyeing
  • Resin viscosity is approximately 1000 centipoise at 72°F (22°C)
  • Cures clear and can be easily sanded and shaped when altered with available additives
  • Mix ratio of 5:1 (resin to hardener) when using 205, 206, or 209 hardeners; 3:1 ratio when using 207 hardener

Multiple coats of 105 Epoxy Resin create a superior moisture barrier and a tough, stable base for paints and varnishes. When modified with West System fillers, 105 mixtures will bridge gaps and fill voids and can be sanded and shaped when cured. The resin must be mixed with a separately purchased West System hardener to cure properly. Choose from Fast (205), Slow (206), Special Clear (207), or Extra Slow (209) hardeners based on your temperature conditions and desired working time.

Organized website!

I ordered a bike rack and the rack was shipped promptly, and was exactly what I ordered. Best price on the internet

quick and easy so far, hopefully shipping will be the same.

Found what I needed at a price that was better than any other I found in my online search. Ordering was easy. I will definitely access your website for products as I continue with my car build process.

Items were easy to find BUT the pictures for MOOG sway bar link were of Tie Rods. So confusing I had to call Tech support for clarification of my ordered parts.

I was skeptical at first but checked it all out and it looked ligit, placed my order and wow low prices, first rate shipping and top quailty product. I am sold! will look to Autoplicity for future purchases, already told many of my friends about the fantatic deals at Autoplicity.

GREAT deals you should be more up front about shipping delays and how long it will take to get your products other than that great overall

Excellent price on name brand items, best prices for Bosch oxygen sensors.
