Rubber Cement question

[Rawhide]

I keep my rubber cememt in a teflon pot, just as I do my contact cement. I know every so often the contact cement needs thinner to maintain consistency, but the rubber cement seems to be thinning on its own. Is this common? Is there a way to combat this?

Thanks,

Marlon

Sorry I can't answer your R.C. question....

I've been buying small cans of C.C. from Tandy, but they get all thick and goobery after a month. I would like to get 1/2 gal from my local home building supply store for about $6, or less than the cost of shipping! What exactly do you use to thin C.C.?

Hey Marlon,

Rubber cement thinning on it's own....the only reason I can think of for this is that there's more solvent staying in the bottle than is being removed. RC has a pretty high volatility, and the partial pressure in the bottle may be playing a role here. I suggest setting out a test batch and letting it breath for a couple of hours, letting some of the VOCs escape. That should more or less equalize the mix.

Of course, I'm FARRRRRR from being a chemist, so I may be totally off track here.

Hilly, Tandy carries a cement thinner that's used to thin it down.

Twin, Thanks for the idea. I may give it a shot. It's only about a 1/4 of a quart left in the pot, but I don't know if that's the problem since the remainder in the can still has good viscosity.

HMMM????

Hilly,

You can use Lacquer Thinner. Don't try Paint Thinner it is not strong enough to mix in.

We use a fair amount of contact cement on Aircraft panels. To dissolve the old contact cement and to thin it we use toluene. It can be found in the paint section of most hardware stores with other solvents. Refer to the MSDS.

Everyone has thier favorite cement but whatever it is be sure to mix, shake or sturr the container before use. Cement is just like anything else, you let it set and some of the components will settle. I buy duall 88 by the gallon and have not had much trouble with it needing thinned. Maybe because I shake well before use. I gave up on my pot a long time ago because of these problems. I just put my cement in an old water bottle with a small hole in the lid. Squeeze out the amount you need and use small scrap of sheepskin to apply. Stick the sheepskin over the hole when done and it is sealed until next time. My thoughts on rubber cement is buy the best you can find. I buy the Barge or Masters Brand of rubber cement it works a lot better that some of the others I have tried in the past. I think the secret here, (if there is any) is to keep your containers sealed when not in use and shake, stirr or mix well before use.

Thanks Randy. When I run out I will go with a better brand, and remember to shake well.

I may be wrong about this, but I think that the formula for rubber cement was to disolve some tan rubber bands in acetone. I think the source for acetone is cheap, unscented finger nail polish remover.

Thanks,

I may be completely wrong, and I've never had any experience with this at all. . . But I thought I had heard somewhere that the rubber cement thinning by itself had something to do with the teflon pot.

Has anyone else heard of anything like this?

On the subject of thinning CC... I have some acetone lying around. Does anyone have experience with using this to thin CC?

I like the idea of transferring CC to a water bottle.
