CA Debonder

I have heard that nail polish remover is pretty much the same stuff. I do not know this for a fact. I used the commercial stuff just last night which worked well so I will keep using it. I bought the bottle at least two years ago and have probably only used 5% of it. If that. At that rate, I dont think I need to find a cheaper alternative, myself.

acetone ?

Debonder is almost pure Nitro Methane.

No, de-bonder is acetone. From the Pacer Tech web site, the MSDS for Zap A-7 Debonder :

MATERIAL SAFETY DATA SHEET DATE: 07/23/02

Revision #3 Page 1 of 2 Section 1 For Chemical Emergency Only: PACER TECHNOLOGY HAZARD RATING In the US and Canada: (800) 424-9300

(didn't quote the whole MSDS sheet)

You can buy a whole ounce of acetone unnder the Zap Z-7 Debonder label from Tower Hobbies (or any hobby source), or you can buy a quart of acetone at any home improvement store (The BORG, Lowe's, Ace Hardware) for something like ten bucks.

I keep a quart in the building shop, to replenish the Ball jar I keep the CA tips in. The acetone dissolves the CA and keeps the tips looking like brand-new. Cheers, Fred McClellan The House Of Balsa Dust

Acetone, from a paint or home improvement store, is exactly the same thing as high-priced hobby de-bonders, for a _lot_ less money.

A word of caution, though. Some plastics don't like acetone at all. IIRC polycarbonate is one. Matter of fact, polycarbonate doesn't like many chemicals at all.

DAMHIKT.

Try a small drop on the plastic part where it can't do any harm, and see if the plastic softens or discolors.

The acetone may need a bit of time to dissolve cured CA, but it _will_ dissolve the stuff.

Buy the acetone as Fred says and use it for your debonding, then with all the leftover acetone, use it to clean the CA bottle applicator tips. I pour acetone in a baby jar, close the lid, and let it soak the applicator tips a few hours. Since I started doing that, I've never had to buy an extra tip.

I did some google searches on this, and acetone, acetonitrile and nitromethane all work.

There were some references to 'chlorinated organic solvents' as well with may mean things like dry cleaning fluid?

acetone and nitro methane. Really!

pure acetone doesn't work nearly as well. Most of the commercial stuff has some nitro methane in it.

No really. Better yet, you add a bit of nitro glycerine, some battery acid and shake it up real well. It'll clean up most anything within a 9 foot radius. Double the nitro glycerine and it'll clean out your entire garage in like, a half a second :-)

I try to read the MSDS for every chemical I routinely use, including three flavors of "commercial stuff" debonders.

None of the debonder MSDS sheets I've ever read listed nitromethane.

Fred,

What DID they menti>

I found a couple of web sites - loctite was one, and another I forget. Both mentioned nitromethane as being very good, acetone also good.

Could use a fairly 'hot' glo fuuel then...

Do a google on 'Cyanoacrylate solvent' and see for yourself.

I store my used tips in Debonder that I put into an old film canister. Those plastic "cans" tend to pile up or get tossed.

Wow, kinda expensive use of debonder. Acetone will work just fine for that.

Only one component listed : acetone.

The post is back up the thread somewhere.

OK, lemme rephrase that: Since those plastic film cans tend to pile up or get tossed, I decided to use one to keep my plastic tips in along with a small amount of debonder. Better?
