WEST SYSTEM® Epoxy

Highly trusted by boat-builders, WEST SYSTEM Epoxy is ideal for use as an ultra-tough waterproof coating, a high-strength, gap-filling adhesive or an easily sanded surface filler. The Resin works in conjunction with a variety of WEST SYSTEM Hardeners, Fillers and Pumps for a wide range of applications.

The 105 Epoxy Resin is the base material of the WEST SYSTEM family. A clear, pale yellow, low-viscosity resin, 105 forms a high-strength solid with excellent moisture resistance, and is designed specifically for wood fiber, fiberglass, reinforcing fabrics and a variety of metals.

105 Resin

• 105 Resin viscosity is approximately 1000 cP (centipoise) at 72°F (22°C).
• Coverage for “A” resin containers: Porous surfaces: 90–105 sq. ft. (8.5–10m2) Non-porous surfaces: 120–135 sq. ft. (11–12.5 m2)
• Coverage for “B” resin containers: Porous surfaces: 350–430 sq. ft. (32–40 m2) Non-porous surfaces: 462–550 sq. ft. (43–50 m2)

Combined with 205 Fast, 206 Slow and 209 Extra-Slow Hardeners, the cure time of 105 can be fine-tuned and adjusted for a wide range of temperatures. For coating and roller applications, it can be combined with 207 Coating Hardener, which provides excellent thin-film characteristics to flow out and self-level without "fisheyeing." Cures clear to light amber, so you can achieve a natural wood finish when coating with varnish.

205 Fast Hardener

• Pot life at 72°F (22°C) – 9 to 12 minutes.
• Cure to a solid state – 6 to 8 hours.
• Cure to maximum strength – 1 to 4 days.
• Minimum recommended temperature – 40°F (4°C).

206 Slow Hardener

• Pot life at 72°F (22°C) – 20 to 25 minutes.
• Cure to a solid state – 9 to 12 hours.
• Cure to maximum strength – 1 to 4 days.
• Minimum recommended temperature – 60°F (16°C).

209 Extra-Slow Hardener

• Pot life at 72°F (22°C) – 40 to 50 minutes.
• at 95°F (35°C) – 15 to 20 minutes.
• Cure to a solid state at 72°F (22°C) – 20 to 24 hours.
• at 95°F – 6 to 8 hours(35°C).
• Cure to maximum strength at 72°F – 4 to 9 days.
• Minimum recommended temperature – 70°F (21°C).

206 Coating Hardener

• Pot life at 72°F (22°C) – 22 to 27 minutes.
• Cure to a solid state – 9 to 12 hours.
• Cure to maximum strength – 4 to 7 days.
• Minimum recommended temperature – 60°F (16°C).

When combined with 404 High Density Filler (optimum strength) 407 Low Density Filler (optimum volume) or 406 Colloidal Silica Filler (optimum versatility), WEST SYSTEM epoxy will bridge large gaps and voids and can be easily sanded and shaped when cured. It has no strong solvent odor, making it far safer and more pleasant to work with.

Round out your set with the 300 Mini Pump Set, which includes one resin and two hardener pumps calibrated to dispense perfect ratios every time. Pumps mount directly on the resin and hardener containers, eliminating mess, and include extension tubes for various container sizes. NOTE: “A” and “B” sized resin containers correspond with “A” and “B” sized hardener containers. The 300 Mini Pumps can be configured to fit any size.
