Choosing a West System Hardener: 205 Fast, 206 Slow or 207 Clear

West System 105 epoxy resin is a clear to pale yellow, low-viscosity resin that wets out timber fibre and cures once mixed with a hardener. Choose the hardener by working time and finish: 205 Fast Hardener for a quick set, 206 Slow Hardener for longer assembly in warmer conditions, and 207 Special Coating Hardener when the cured epoxy needs to look clear. The 205 has a 9 to 12 minute pot life at 22°C and works down to 4°C, while the 206 gives 20 to 25 minutes at 22°C and needs at least 16°C.

205 Fast Hardener: 5 parts resin to 1 part hardener. Best for a quick set and cooler workshops.
206 Slow Hardener: 5 parts resin to 1 part hardener. Best for longer working time in warm conditions.
207 Special Coating Hardener: 3 parts resin to 1 part hardener. Best for clear coating and finishes.

The 205 and 206 are not for clear coating. For other brands, see all Epoxy & Resin Adhesives.

Resin Sizes, Fillers and Pigment for Bonding, Filleting and Coating

The listings describe the 105 resin as solvent-free with a high flash point, curing to a moisture-resistant solid with no shrinkage. It comes in 500ml, 1 litre and 4 litre packs, the 205 and 206 hardeners in 100ml, 200ml and 800ml, and the 207 in 330ml and 1.33 litre, so a small repair and a larger glue-up use the same epoxy. The West System 413 Microfibre Blend thickens mixed epoxy into a high-strength adhesive for bonding, filleting and hardware bonding. West System Black Pigment colours mixed epoxy but is not colourfast and may degrade in sunlight, so use it indoors, in shade or under a UV-resistant topcoat.

Pumps, Syringes and Mixing Pots for Measuring and Applying Epoxy

The West System pump sets, such as the 1.2ltr Pump Set, are reusable, easy to clean and transfer to new packs. The West System Mini Syringe Set places epoxy into gaps that are hard to reach, and the 500ml mixing pot is reusable. For casting projects, see Resin, and for wood glue, see Titebond.
