West System Epoxy - Woodworking
West System Epoxy - Woodworking
West System is the industry standard epoxy for high-strength waterproof adhesives.

The #105 epoxy resin is mixed in a 5:1 ratio with the #205 and #206 hardeners, and a 3:1 ratio with the #207 hardener to form a high-strength solid with excellent moisture resistance.

The #205 fast-cure hardener has a working time of about 60 to 70 minutes at 20°C/70°F with a minimum cure temperature of 4°C/40°F. The #206 slow-cure hardener has a longer working time of 90 to 110 minutes at 20°C/70°F with a minimum cure temperature of 16°C/60°F.

The #207 special coating hardener was developed for coating and fiberglass cloth application where an exceptionally clear, moisture-resistant, natural wood finish is desired. The 105/207 mixture resists clouding in humid conditions and has a low blush formation. Three coats or more can be applied in one day without additional surface preparation. The #207 working time is 110 to 130 minutes at 20°C/70°F with a minimum cure temperature of 16°C/60°F.

The curing time for maximum strength is 1-4 days for #205 and #206 hardeners, and 4-7 days for the #207.

The 5:1 kits contain 32 fl oz (946ml of resin and 7 fl oz (207ml) of hardener, and the 3:1 kit contains 32 fl oz (946ml) of resin and 10.6 fl oz (310ml) of hardener. Kits include three dispensing pumps and a 30-page manual. Components are also available individually.

The fillers thicken the mixture for specific applications. All cure to an off-white color, except for the #407, which cures to a dark red/brown. The #403 microfiber blend is suitable for gap filling. The #404 high-density filler is used for filleting and gap filling where maximum strength is needed, such as screw and bolt holes. The #406 colloidal silica is a thickening additive to prevent run-off in vertical and overhead joints, but can also be used for additional strength or a tougher surface. The #407 is a micro-balloon-based, low-density filler for making fairing putties that are easy to sand or carve. The #410 microlight filler is a thermoplastic-based filler that mixes and sands easily. Its smooth texture produces a fairing compound that allows a fine feather edge.

The repair kit (about 38g of resin, fast hardener, and filler) is ideal for emergency repairs around the boat, shop or home.

Wooden Boat Restoration & Repair is a 78-page booklet that contains in-depth technical information on dry rot and hull and deck plank repairs, plus general information on the restoration of wooden boats with West System epoxies.

Made in USA.
