CA Accelerator?
woodspinner/ Bill Hale
>I had posed a question to an old thread to a chemist about accelerator. I have searched for the answer but can not find it.
What is accelerator made of? I would like to make my own as it has to be cheaper than buying it by the bottle.
Good turning and be safe
Thanks Bill

>I had heard the same about water, instead of the accelerator in the store, and have tried it on several turnings, just misting the wood with water, and it works, can't say that I really have seen a difference, seems to carry the same holding power, with it is the mist or the accelerator in the bottle...try it on a few small test pieces and see if you can tell the difference...Dennis

>They used to use one of the freons as an accelerator. There were also some recipes that cirulated among the model airplane community, but all had their drawbacks. The main drawback to any accelerator is the glue joint is weaker. The set time is only around three seconds so there really isn't any need to weaken the joint.
The one thing that triggers CA is the moisture content in the wood. I have had some wood that I had to moisten as it was too dry for the glue to set. I had to dampened the wood slightly with a spone ti get the glue to set.

Andrew Hilton Strong base = In essence, ammonia, for most commercial CA accelerator formulas. Even a powder can be used such as baking soda. Water and water vapors, being in the 7ph range is "stronger" than the CA itself so it helps to accelerate the CA glue. It doesn't do it nearly as fast as a stronger base like ammonia but it does help speed it along. By the way, ever notice how putting CA glue on some things like foam gets a really rapid acceleration? Anyone care to guess as to why? Aeromatic Amine = This is a tougher one. It's not like you can just run out to the store and say "Hey, I'd like your Aeromatic Amine". It's a chemical that's used in many many household products among others, of course. Baby Oils has quite a bit of it but also some other stuff that interferes a little bit too. (Don't go around trying to extract the oil from Babies, folks!) Simply combining either or both of these two types of things isn't going to get you a commercially prepared CA Accelerator. Nope, it's not quite that easy but they will help in a pinch. Still, these are the basic ingredients to accelerate CA so you can use them as a starter for your own experiments. I did and it's a WHOLE lot cheaper to make your own. - Andrew
>CA (CyanoAcrylate) is "accelerated" by a stronger base and aeromatic amines, basically. So, what does THAT mean, you ask?
