Select a hardener for its intended use and for the cure speed best suited for your job in the temperature range in which you are working. 3. Add one of six WEST SYSTEM fillers to thicken the mixture as needed. Select a filler for its handling characteristics or cured physical properties. Or, add WEST SYSTEM additives to provide specific coating properties. WEST SYSTEM pigments can be used to change the epoxy's color. ## Features - Slow-curing epoxy hardener for extended working time – WEST SYSTEM206 slow hardener is a Made in the USA low-viscosity epoxy curing agent designed for bonding applications at room temp (60 degrees) or higher. - Develops high-strength, moisture-resistant bonds – When cured, 206 produces a rigid, high-strength solid that is functionally waterproof and highly resistant to moisture vapor in structural and protective applications. - Designed to mix with WEST SYSTEM 105 resin – Used with WEST SYSTEM 105 epoxy resin at a 5-parts resin to 1-part hardener ratio, this combination provides excellent bonding and barrier coating performance. - Predictable cure profile across temperatures – At 72°F (22°C), pot life is 20 to 25 minutes, cures to a solid state in 10 to 15 hours, and reaches maximum strength in 1 to 4 days.

I think you will get a idea of coverage there. **Q: Can i use this to paste wood to Concrete ?** A: I have not used it for that. There are a bunch of products on the market that are made to glue wood to concrete. Check with your local building supply store. My understanding is that this West product is for fiberglass to fiberglass ,wood to wood ect. **Q: i bought the 105 and 206 with pumps as set. reading further i dont know if i got the correct products. using on reclaimed pine flooring. any opinions?** A: it works fine for filling voids in wood slabs but it is not a finishing product **Q: How much VOC is there in this product?** A: Hello Adu. There are 9.59 g/L (0.08 lb/gal) of VOC's in the combined resin/hardener system of 105/206.

The slow hardener is the best overall option. It takes overnight to set up but you are rewarded with a super glue job. I use this with 105 rather than any aliphatic wood glues. Wood glues are only when I need something simple and fast like fixing a stripped screw hole. ### ⭐⭐⭐⭐⭐ Pricey but the best material to work with *by on Reviewed in the United States 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. ### ⭐⭐⭐⭐⭐ FAST and low to NO Odor. *by on Reviewed in the United States November 15, 2020* Woah, once I finally got the lid off, I didn’t notice any odor. I had some leftover resin from other kits that I ran out of hardener for and this is the ONLY company on Amazon that I could find to purchase just the hardener. Yes, I know that there’s no good reason to come up short on hardener, but anyway, a leaky pump that defied theLaws of physics was a culprit on top of mixing by weight instead of volume. When working with less than 20ml, it’s difficult to pour and I have yet To find a pump that’s able To Effectively Pump thick resin. Anyway, back to this product, it has a slightly amber tint that doesn’t really change any color additives I used but forget about true colorless clear casting. Fast! Very fast! I only had 18ml in med cup and it was cured in 15 minutes and yes, I mixed it correctly at 5:1. It was still tacky and solid. So, maybe 10:1 if you need more working time. That’s been an hour ago and it’s touchable and not even tacky. ## Frequently Bought Together - West System 206-B Slow Hardener - West System 105-B Epoxy Resin - WEST SYSTEM 300 Mini Pump Set --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/2195958-west-system-206-b-slow-epoxy-hardener-quart-for-extended](https://www.desertcart.no/products/2195958-west-system-206-b-slow-epoxy-hardener-quart-for-extended) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-24*
