West System 206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working and cure time is needed or to provide adequate working time at higher temperatures.
At 72-degrees, 206 Slow Hardener will have a 20-25 minute pot life. When combined with 105 Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties.
Not intended for clear coating applications.

Questions & Answers about WEST System 206 Slow Hardeners:
2012-04-04HERBERT SCHAAK asked: The product description for 206 hardner says ,not intended for clear applications . i want to use it with 4 inch tape to seal seams on a flat bottom canoe. Can I varnish over it and get a nice clear finish or will I have to use a color finish?
+Expand Answers
2012-04-04ALEXANDER NANAI: Hi Herbert, the 206 will dry with a cloudy appearence to the resin. This will help to disguise the fiberglass tape. The finish you decide to use will either enhance (let you see) or cover the repair. It's your choice.
2012-04-04GLENN SIKES: Slow hardener takes on a reddish tint when exposed to moisture prior to mixing (this is only a problem with that leftover can from last year) - also, over time it will become hazy/opaque and degrade when exposed to UV, even under good varnish. I would pick a UV stable brand.
2012-04-04GARY STEVENS: I have used the Slow hardener for clear applications many times. It is more clear than many amber-colored marine varnished. The "newer" hardener for clear applications used different pumps (3 to 1, rather than the 5 to 1 pumps of the Fast and Slow) and ends up being more expensive. The clear coating hardener is a little more user-friendly and, here's the important thing, it has more UV protection.
For your use and most normal uses, the 205 and 206 will work very well if you use something like Epifanes varnish or a solid-color paint.
In my experience, which goes back to the early 1980s, I always use the Slow, mainly because I like a long pot life and I'm never in that much of a hurry to have the glue kick off.
You don't mention what the canoe is made of. It could be wood, canvas over wood, plastic, aluminum. West will stick to most anything except vapor barrier poly plastic and similar plastics. Do a test!! Give it 24 hours, then stress to the breaking point, if you can make a sample.
As always, abrasion with sandpaper will afford a good mechanical grip. Clean with denatured alcohol or lacquer thinner before gluing.
In choosing your clear finish, try to find one that is intended for below waterline use.
Wood strip canoes are typically built with West and Dynel cloth with 3 or 4 coats of Slow over the cloth, followed by several coats of something like Epifanes over that. If the canoe will be in the water all of the time, a bottom paint would be a good idea.

2012-04-04JIM WOODS: Never used this with tape but in thin layers it turns a light amber. If you need water clear then probably won't work but if your varnish gives an amber cast anyway then it may be OK.
2012-04-04JOHN CRONIN: This hardener does have a slight amber hue to it , and if you have it sitting around for long lengths oif time (many months) , this hue darkens even more. But if your using this over 4 inch tape, (I'm assuming this is a wooden canoe), well saturated tape will result in seeing through the tape to the underlying structure with a "wet" look until you sand it. After sanding and some spot touch up to missed spots, this will take on the look of any good solvent based varnish. So I wouldn't hesitate in applying a varnish to the taped seems and the rest of the surface to achieve a nice amber hue look, but I wouldn't call it clear.
2012-04-05THOMAS STEARNS: Here're some general answers on epoxy use in boatbuilding
1. If West says the 206 is not intended for clear coat applications then why use it? You will probably see a darker band where the 4" tape is which could be objectionable.
2. Why use a slow hardener anyway? West probably has a medium hardener that they say is appropriate for your application. Working time is a function of the temperature in your shop, temperature of the resin and hardner, the mass of resin/hardener and the thermal conductivity of the surface you're working on. If you mix in small batches--for example, less than a total of 150 grams or 5 oz or so, mix thoroughly and then dump the mixed resin onto the tape and spread it out so there's no big mass of it in any one place (like the mixing cup) then it won't exotherm or "run away" with self heating and you can use a "normal" hardener. I use the West 8oz plastic mixing/measuring cups, stir for 30 seconds or so and get the stuff onto the work and spread out quickly and have no problems. My shop area tends to be cool--low 50's in the winter and maybe 70ish in the summer.
3. A much bigger worry than change in colour is "blushing." Blushing in epoxy coatings is not the same as blushing in paints or varnishes--it's much worse. Some "how-to" epoxy books tell you that you must wash cured epoxy with warm soapy water to remove "blush" before you can proceed with a varnish overcoat or another layer of epoxy. If you have blush and don't remove it the next coating may fail to cure or harden properly and adhesion may be poor. Blushing is caused by inadequate quality control in the hardener manufacture and is aggravated by high humidity so be careful to avoid wet days. And use a system which sells a "No Blush" hardener. I use MAS and their "No Blush" normal hardener and do not bother with a soapy water wash-down. Who wants to get their partially finished boat wet??
This was my first time every using an epoxy and I was a bit concerned about my lack of experience. I got the pumps (I highly recommend them for proper measurements), read the directions on the epoxy, hardener and pumps and it was easy breezy. Great results!

Comments about WEST System 206 Slow Hardeners:
I'm now using this product with West 205 resin on a new multi-layer bottom for an antique Chris Craft. It allows plenty of time for clamping and fastening and completely cures in a couple of days resulting in a bottom much more solid and leak resistant than the original construction.

Comments about WEST System 206 Slow Hardeners:
Great epoxy for using on laminating wood. Very thin and flows out easily. I recommend getting a good postal scale so you can do some small batches. Easy ratio to remember, hardener is .20 of the resin. So a 5 gram of resin needs 1 gram of hardener. Dries real hard too.

I have been using WEST system since 1980. Never a problem. I balance my use of 205 and 206 hardeners for seasonal conditions. Think before you mix. Plan each project. All the best.

Great Hardener. I started using 206 slow when I was new with glass, and continue using it today because it provides a comfortable working pace. Setting project next to a space heater expedites curing once project is laid up.
