I used to know this but when a customer asked today I drew a blank.
Can anyone help?
Mike
Taking a stab in the dark here, but I say 1 part epoxy to 5 parts acetone?
I use about 1:4 of Devcon Long-Set epoxy to acetone. That works well for wipeon. I tried it with spray and it didn't do so well. Someone reported a 1:10 epoxy to MEK does well for spraying.
1 part epoxy to 3,4 or 5 parts acetone. Everyone uses a little different mix I think. The more you thin it the easier it is to work with. I thin it quite a bit and it allows me to wipe over it a couple times. I put about 4 thin coats on a knife handle. If it is thicker, say 3 parts acetone then you can only wipe it once as you put it on because it is so sticky. Chad
Chad,
Once you mix it up at 5:1, can you save the thinned material in a sealed jar while it cures on the wood. Will it last for several wipe on coats, or do you have to make a couple of batches?
Steve
The mix will keep several weeks in a sealed jar.
I like to go really thin...1 to 10 or more...for a first coat on arrows. I think I get a bit more penetration that way and the shafts seem more durable. Then I switch to 1 to 5...
Th exact ratio isn't real important but use the MEK as JS (now you remember who JS?!) said for better results and spray-ability.
The exact ratio isn't important. In fact I never have measured either the epoxy or acetone. I just add a splash of acetone until it is kind of a watery consistancy. I don't want it thick at all or it gets too sticky.
What's the work time on the MEK mix?
Mike
Any kind of epoxy can be used ???
Maybe this would be a good addition to the Hints and tricks section. I'd LIKE to say I can keep it in my mental section, but you know how that goes wingnut...
Mike
I use Devcon 2-ton epoxy in the double syringe. The regular stuff, not the quicker setting stuff. Has worked good for me so far. I apply with one of those foam brushes and have found that the thinner I go the more passes I can make over the same spot before it starts getting tacky. I've also heard thae MEK gives you a little more time for multiple passes. So far I've only used acetone.
Aaron
Mike, with the regular 2ton epoxy I buy I mix enough acetone or lacquer thinner to get the consistancy I want. I have never used a formula. Pat
Thanks guys,
I'll let my customer know. I think he is going to use on the pens he turns.
Mike
Only use two-ton of any brand, never 5 minute as it is garbage. I tried once with smmoth-on and that was a failure.
Work time with MEK is enough unlike withe acetone. Don't know what that is in minutes just "some" time as opposed to none.
MEK ?
Methyl-Ethylen-Ketone or what is it?
Please help me!
Yes, Methyl Ethyl Ketone. It has a lower vapor pressure is why it is better than acetone.
Just be careful with the MEK guys.....it is supposed to be some very bad stuff.
