West System206-B Slow Hardener

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.

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.

Hardener arrived faster than expected. I have been using the West System for years because of its reliability and predictable handling characteristics. While it may cost more per ounce than other brands, I consider my labor as a valuable asset, and to me it seems foolish to try to save a few dollars to jeopardize a task that will take many hours to do right the first time.

Been using West System 206 hardener for years refinishing carbon fiber racing boat hulls.It’s excellent for my needs!

Very good product. I have used this several times in the past and highly recommend it.

Product was fresh. I've used seven gallons of west system epoxy on my boat rebuild project. So I had to purchase 205 and 206 hardeners in the quart size seven times. This is only the second time that the hardener wasn't colored amber. (which is still ok to use according to West System tech support) It turns that color from age. This has changed my way of shopping on Amazon which is turning into a dumping ground for old and expiring or already expired products. I bought a quart of gelcoat from a third party seller that had the expiration date sanded off. I didn't discover this until nearly a year after I purchased it. Since I had no experience with fiberglass before this project, I didn't know that gelcoat has a shelf life of about one year.

West System epoxies and hardeners have been working great for me. The 206 hardener dries hard and clear.Amazon's packing of the item is my only complaint. The container wasn't in a bag and there was nothing else in the box to keep it from moving around during delivery. The container leaked into the box making a bit of a mess.

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.
