Is there a home brew for CA Accellerator?

No surprise.

Acetone is a solvent for CA. I keep formerly clogged nozzles soaking in it and switch if I forget to clear one in the heat of gluing.

The hardener appears to be an aromatic alcohol rather than a ketone. Home brews normally just use a basic substance like bicarb solution. It's too cheap to screw around with such things, in my opinion. Bicarb has a tendency to leave a really quick whitened film.

I've always understood that it was formic acid, but no guarantee.

Oww.... come on, now. There is cheap, and there is silly. Don't risk the integrity of your adhesive by using something you found under the bathroom sink. Hours and hours of work, yet not willing to put .02 into the hat for accelerator?

I have found that used correctly (read: bathing/soaking not required) accelerator lasts for a long, long time. I have used this combo now for three years.

$9 plus shipping? For that much product? I don't think you can go wrong.

Given that cure takes forever on acid woods, I'd put that one out of my mind.

I was just knocking around an idea - looking for the alternative if it was sitting under my nose would be better than having to make the trip to WC to get a new bottle!

I understand that anything with an -OH radical will work. They say water mist works slightly. I would expect alcohol to work. I agree, however, that the real stuff works so well that it's a no-brainer.

Satellite city have just offered for sale a new aerosol accelerator that will not evaporate in the heat or go off in the sun. A little goes a long way. There are many sources for it, I can provide a link should anyone require. it.

Water can work as an accelerator, but it depends on the water. "Hard water" is good, and the harder the water the better. City water is not good because the chlorine and fluorides are decelerators.

The cellulose in cloth or a paper towel will act as an accelerator if you are using the CA as a finish.

=======>I seem to recall that this topic came up once before and a suggestion was put forth that to speed setting of the CA to spray a bit of water in the area to be joined and then apply the CA with even giving it a quick spray. I have tried that and it seemed to work. However, I agree that the use of a commercial accelerant is cheap enough that it doesn't warrant doing under the kitchen sink chemistry.

Yes, please!

I put some C/A on the wood and started spreading it with a rag. The cure took off and attached my finger to the rag. There was lots of heat, and I wound up with a painful blister with a rag glued to it.

I don't do that any more.

Acetone is CA REMOVER if you like bargains, go to your local dollar store, purchase a 99cent PINT of nail polish remover it un-super-glues fingers quite effectively

LOL! CA is water activated by design. The moisture in the paper towel acts as a curing agent. One formula for an accelerator (told to me by a CA industrial adhesive mfgr.) is water and sodium bicarb mixture sprayed on one surface and CA spread on the other. The bicarb retains a little moisture, even after the surface water has evaporated.

Yes, its a mixture of water and acetone.

Leo,

Ik weet zeker dat ik dat van iemend gehoord heb die zegt dat van een wel ingelichte persoon te hebben gehoord. Nogal vaag he, meer kan ik daar niet over zeggen. Tot nu toe heb ik het nog niet geprobeerd, is nog niet nodig geweest, bovendien is het tamelijk smerig spul, zowel de lijm als de aceton, dus ik probeer eerst een andere oplossing te verzinnen dan meteen naar secondelijm te grijpen.
