What is the stuff they use to help accelerate CA glue curing?

Hi all,

Does anyone know what the chemical name of the accelerator for CA glue??
Thanks

Al

Actually, I think it's a mixture. Essentially I'll bet it's some type of amine, but I'm not sure. If you're trying to come up with a cheaper source bear in mind that they may have done a fair amount of work to get the accelerator to work properly, thus you may have something of a project on your hands.

Anybody else noticed the small print on bottles of accelerator saying that use of it may (will?) give a weaker bond?

The stuff that I have here smells quite strongly of lanolin, but I believe I read on the net somewhere that you can use a super saturated solution of sodium bicarbonate to do the job - it might be worth a little experiment.

I don't use much CA myself due to a bad reaction and have only used the kicker once or twice.

Isopropyl Alcohol,
N,N-Dialkyltoluidine and
Hydroquinone

At least that is what is in the stuff I use.

Have fun!

Back in the old days before kickers or accelerators for CA, we used Arm and Hammer baking soda. You can sprinkle it on a joint and then thin CA it ... sometimes we mixed it with water in a very strong mixture and sprayed it on parts to be joined. The dry method worked the best for me. I still use it sometimes to make a very strong light filleted joints. Be careful ... it really sets up FAST ... Try it ... you'll like it. Cheap too.

Al,

I used to use that stuff all the time but I don't even know where my bottle is now. The time it takes to set up thick CA isn't too bad and as previously noted, using an accelerator will make the joint weaker. I find it makes the joint brittle.

How is the DuskStik coming along? I know you wanted to try a Speed 280 on it. I put an M100 from www.parkflyers.com on mine and it's a little rocket. Battery life is cut in half though.

Thanks to all for replying.

Hi Doug,
I finished the Duskstik but haven't had the
time to fly the plane. It either has been too windy or no time. I did install a 280 on it. I hope to fly it this weekend.

Why would you want to accelerate CA. It cures in 30 seconds for the thick stuff and instant for thin. What gives? (Note: I'm not
arguing I just don't understand.)

Sometimes after the pieces are bonded together with thick CA,there is a small amount of "wet" CA on the surface.I sometimes mist accelerator onto these surfaces to keep them from sticking to my leg or something.

I'll add to this. Accelerator sprayed on ply and light ply before glueing will help make a better bond.

If needed, you can add slow or medium CA 'fillets' to joints for a bit extra strength. As you know, slow or medium CA will not cure quickly and the accelerator helps things along. Yes it will make for a more brittle glue job, but better that than nothing.

I like to make a CA fillet when a butt joint is used in a high stress area.

Have fun!

Steve

My understanding of how CA works is that an alkaline substance will accelerate the glue and an acidic substance will slow and even dissolve the bonded glue. I have tried using Javex to debond and it does soften the cured CA.

As mentioned sodium bicarbonate acts as an accelerator and it is basic.

You can use anti-acid pills used for stomach indigestion to accelerate the glue. I found that the ready made accelerators work best though.

Cheers

Lyndon

Please email me when you do. I'd love to know how the S280 works out. I expect it will need to fly a bit faster due to the increased weight.
