West System is the industry standard epoxy for high-strength waterproof adhesives. There are three epoxy resin kits available.
The #205 fast-cure hardener has a working time of about 60 to 70 minutes at 70°F (20°C) with a minimum cure temperature of 40°F (4°C).
The #206 slow-cure hardener has a longer working time of 90 to 110 minutes at 70°F (20°C) with a minimum cure temperature of 60°F (16°C).
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 70°F () with a minimum cure temperature of 60°F (16°C).
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 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.
Thickeners for these mixtures are available separately.
