Overview
|
WEST SYSTEM brand resins and hardeners, form a two-part epoxy system developed by Gougeon Brothers specifically for wood and composite boat construction. Rutan Aircraft Factory now recommends WEST SYSTEM epoxy for certain homebuilt aircraft applications, particularly where a moisture resistant epoxy is desired. 105 Resin is the base material on which all of the WEST SYSTEM epoxy systems are built. The resin is a clear, light amber, low-viscosity liquid. It is designed specifically to wet out wood fiber. With roller applications, it possesses excellent thin film characteristics in flowing out and is self-leveling without fish-eyeing. Its relatively high flash point makes it safer to work with than polyesters. It can be cured in a wide temperature range, then sanded and shaped. It cures quite clear so that the natural finish shines through.
205 Fast Hardener, when mixed with the 105 Resin in a ratio of 5 parts Resin to 1 part Hardener, yields a high-strength, rigid solid with excellent cohesive properties and provides an excellent moisture vapor barrier. The 105 Resin/205 Fast Hardener has a pot life of 10-15 minutes at 70°F. It is also recommended in coating applications where natural finishing is desired. Partial cure time at 70°F is 5-7 hours. 206 Slow Hardener is a low-viscosity mixture of polyamines. The 105 Resin/206 Slow Hardener has a pot life of 30-40 minutes at 70°F. It is normally used when extended time is needed for large coating and bonding applications. It is especially well suited to working in warmer climates. Partial cure time is 9 hours at 70°F. Order by size and hardener below. Note: Pumps sold separately. Ratio pumps consists of three pumps to cover 301 and 303 A, B, & C kits. Resin pump fits either gallons or quarts. |

Reviews
The best epoxy available.
Being the first epoxy used on small wood projects I’m soooo impressed with this stuff. I really like the labeling/ font/ colour etc of the packaging, Simple & Effective. Works wonders on small cracks! The viscosity is amazing for that. I like the slow cure time as it’s less stressful as you have plenty of time to work it. Amazing!
Great, thanks!
Works great for sealing wood to prevent rot.
As with past orders at least one of the metal containers was dented, fortunately not leaking.
The West System of epoxy systems is one of the simplest products to use, the are quite expensive, but the product does exactly as advertised, and they made the product simple to use. V/r Mick Cowell
Unbelievable fast shipping. Order late in the day, was at my shop early next morning.
Excellent service! Good quality product. Works exactly as described.
Cures up nice and the pumps available for the west system are excellent, they make if fast, clean, and easy to make up small samples of resin.
Works as advertised.

Yes and no. This product is ideal for fiberglass applications. It is not intended for use with Dacron or Poly-Fiber fabrics.
This will all depend on what the builders manual recommends. You can use a filler with the West System kits, but you will need to check where this will apply to your aircraft application.
There is a 2-year shelf life, the hardener should still be reactive with the resin.
