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 70F. It is also recommended in coating applications where natural finishing is desired. Partial cure time at 70F 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 70F. 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 70F. 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.

I have used this product on multiple occasions and have always had excellent results. The available pumps allow for quick and accurate mixing and less waste when doing jobs requiring lengthy build up times such as the RV aircraft canopy fairing.

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!

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Do the West Systems Epoxy kits work well with fabrics?

Yes and no. This product is ideal for fiberglass applications. It is not intended for use with Dacron or Poly-Fiber fabrics.

Q: West System recommend for bonding that you wet up wood with 2 part epoxy, but that you then add fillers to thicken the epoxy before applying a thicker gap filling coat and clamping. For aircraft use, are fillers recommended or just the 2 part epoxy?

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.
