Description

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

The #205 and #206 hardeners are mixed in a 5:1 ratio with #105 epoxy resin, and the #207 hardener in a 3:1 ratio with the epoxy resin 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 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 (20°C) with a minimum cure temperature of 60°F (16°C).

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

The #105 epoxy resin is available separately. Kits containing the resin, hardeners, dispensing pumps and a 30-page manual are also available.

The #205 and #206 hardeners are available in a 7 fl oz container; the #207 hardener is available in a 10.6 fl oz container.

Made in USA.
