WEST System Epoxy was developed in the late 1960's and early 1970's to work as both an adhesive and coating since then it has established itself as a industry leader in epoxy technology. WEST epoxy bonds well to many substrates including wood, fiberglass, carbon fiber, and metals. WEST Epoxy is also highly resistant to water penetration. WEST System Epoxy is available with 4 different hardeners; 209 Extra Slow Tropical Hardener, 207 Special Clear for clear finished wood parts, 206 Slow, and 205 fast hardener.
This West System 303 (3:1 ratio) Positive Displacement Pump dispenses three parts resin and one part hardener (3:1) by volume. It consists of two separate parallel pump systems, one for the resin and one for the hardener. The two systems are operated simultaneously by a single lever. The pump delivers 2.3 fl oz of resin and hardener per full stroke of the dispensing lever. The reservoirs hold two gallons of resin and one gallon of hardener. For use with 105 Epoxy Resin and 207 Special Clear Hardener or 209 Extra Slow Hardener.
WEST System 404 High-Density Adhesive Filler is an epoxy thickening additive. We developed it for maximum physical adhesive properties in hardware bonding, or anywhere that high-cyclic loads are anticipated. Blended with epoxy, it makes an excellent gap filler or structural fillets. Use 404 High-Density wherever you need an especially strong bond. You can blend it into any WEST System 105 Resin/20X Hardener combination, G/flex Epoxy 650, or G/5 Five-Minute Adhesive. Blended with epoxy, it will cure to an off-white color.
WEST System 406 Colloidal Silica is an epoxy thickening additive used to control the viscosity of the epoxy. It prevents epoxy runoff in vertical and overhead joints. This is a very strong filler. It creates a smooth mixture, ideal for general epoxy bonding and filleting. It is also our most versatile epoxy filler. Often used in combination with other fillers, 406 can be used to improve strength, abrasion resistance, and consistency of epoxy fairing compounds. The result is a tougher, smoother surface.
WEST System 407 Low-Density is a blended microballoon-based fairing filler for WEST System Epoxy. Add 407 to a mixture of epoxy resin/hardener to create a fairing putty. It’s easy to sand or carve this putty once it has cured. Low-Density Fairing Filler filler is reasonably strong on a strength-to-weight basis. You can blend it into any WEST System 105 Resin/20X Hardener combination, G/flex Epoxy 650, or G/5 Five-Minute Adhesive. Blended with epoxy, it will cure to a dark red/brown color.
WEST System 410 Microlight is the ideal low-density filler. When you blend it with epoxy, it creates a light, easily-worked epoxy fairing compound. It’s especially suited for fairing large areas. We formulated Microlight to mix into epoxy more easily than typical fairing fillers.
After epoxy thickened with 410 cures, it is about 30% easier to sand than most other epoxy-based fairing compounds. Epoxy thickened with Microlight feathers to a fine edge. It’s more economical for large fairing jobs.
We don’t recommend using 410 under dark paint, or other surfaces subject to high temperatures.
WEST System Epoxy is a versatile epoxy system that has been around for decades and is trusted by craftsmen worldwide. In our books and videos section we carry many manuals written by WEST System for the use and application of WEST epoxies in various different projects.
Recommended Temperature Range for 205 Hardeners is 40F to 80F, at 72F the 205 hardener has a 9-12 minute pot life, keep in mind that epoxies set up faster in large masses or hot temperatures.
Recommended Temperature Range for 206 Hardeners is 60F to 90F, at 72F the 206 hardener has a 20-25 minute pot life, keep in mind that epoxies set up faster in large masses or hot temperatures.
Recommended Applications for WEST 206 Hardener are general bonding, fabric application, and barrier coating.
Recommended Temperature Range for 207 Hardeners is 60F to 90F, at 72F the 207 hardener has a 20-25 minute pot life, keep in mind that epoxies set up faster in large masses or hot temperatures.
Recommended Applications for WEST 207 Hardener are fabric application and wood coating where a crystal clear finish is desired. Such as wood strip or stitch and glue boats.
Recommended Temperature Range for 209 Hardener is 70F to 100F, at 72F the 209 hardener has a 40-50 minute pot life, keep in mind that epoxies set up faster in large masses or hot temperatures.
Recommended Applications for WEST 209 Hardener are general bonding, fabric application, and barrier coating.
WEST System's heavy duty, flexible plastic roller pan allows you to “pop out” epoxy after it has cured so the pan can be re-used. Eliminates the need for liners when working with epoxy.
A toughened, versatile, liquid epoxy for permanent waterproof bonding of fiberglass, ceramics, metals, plastics, damp and difficult-to-bond woods. With a modulus of elasticity of 150,000 PSI, it is a bit more flexible than standard epoxies and polyester, but much stiffer than adhesive sealants. This gives G/flex 650 the ability to make structural bonds that can absorb the stress of expansion, contraction, shock, and vibration. It is ideal for bonding dissimilar materials. It can be modified with WEST SYSTEM fillers and additives, and used to wet-out fiberglass tapes and fabrics. Mixed at a 1:1 ratio, G/flex 650 gives you 45 minutes of working time at 72°F. It reaches an initial cure in 7 to 10 hrs and full cure in 24 hrs.
