## Description

206-B Slow Hardener

## Features

- 206 SLOW HARDENER is a low-viscosity epoxy curing agent. It is useful in a majority of bonding situations, and when extended working time and cure time are needed. 206 Slow Hardener produces a slow epoxy cure that develops its full physical properties at room temperature. It yields a rigid, high-strength moisture-vapor resistant and functionally waterproof solid.
- MIX WITH WEST SYSTEM 105 Resin in a five-part resin to one-part hardener ratio. The resulting cured epoxy is a rigid, high-strength, moisture-resistant solid. The combination of 105 Resin/206 Slow Hardener has excellent bonding, coating and barrier coating properties.
- CURES AT TEMPERATURES as low as 60°F (16°C). Will cure faster at warmer temperatures. Pot life at 72°F is 20 to 25 Minutes. Cures to a solid state in 10 to 15 hours. Cures to maximum strength in 1 to 4 days. Minimum recommended working temperature is 60°F (16°C).
- PAIR WITH 105-B WEST SYSTEM 105 Epoxy Resin at a 5-parts resin to 1-part hardener ratio.
- EASILY MODIFIED with WEST SYSTEM Fillers, Additives, and Pigments to suit the job at hand, whether coating, applying fiberglass, structural bonding, or fairing. Not intended for clear coating.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good, Strong.
*by W***P on December 7, 2024*

I'm almost at the end of this can. It's not something I use often, but when you need epoxy, West System is a good choice. I undoubtedly will buy this again.

### ⭐⭐⭐⭐⭐ Pricey but the best material to work with
*by O***S on June 11, 2025*

Nice to get it at home versus finding a West Marine supply store 2 hours away. As always, product does what it says it will and work s perfectly. Just you wish it was a little cheaper as the price seems a bit inflated but about the same that you would spend at a store.

### ⭐⭐⭐⭐⭐ Great for woodworking
*by T***3 on December 4, 2017*

I use this with the 105 resin to fill cracks and imperfections in solid wood. You can either dye it to a color you want or use it clear as is. You’re going to end up with a lot of bubbles as with any epoxy, but I use a small torch with indirect heat to pop those and get a perfect finish every time. It’s difficult to work with so if it’s your first time I would recommend watching some videos on YouTube or something to learn more before you dive in. But the product works exactly as intended. Don’t expect to fill a large crack all in one pour. Work in stages or you’ll end up with voids. Get the pumps that they sell as well in order to get the perfect mix and make it easier on yourself.
