Duco Cement

[Tom Dempsey]

I've been experimenting with Duco Cement Pegamento pn 402 62435 for adherring card stock to wood and it's been impressing me favorably. However, it has been concerning to me that there may be long term issues with this cement on models due to outgassing, etc. Any of you old heads care to weigh in on the merits or otherwise that you know of?

Martin is your guy for this. Duco is probably the same thing we use to glue aircraft fabric. It is either nitrocellulose acetate or something similar - the solvents do not hang around very long at all.

[Tom Dempsey]

It says it contains acetone and 2-Propanol so I'm inclined to agree with you, but, I thought it best to check before I start closing up the box.

....card stock to wood .....outgassing........

acetone and 2-Propanol

Should not be a problem - both are porous and neither air tight and neither react to solvents like styrene does/can....

Thanks guys, I shall proceed with trepidation.

Embrace it.

I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain.

[Tom Dempsey]

I shall, right up to the point where the worm engulfs me.

Usul has called a big one!

Duco is an additive glue rather than a solvent adhesive. You may want to thin it with acetone for laminating to avoid lumps between the sheets. Its best to clean off any excess before it dries. I've got a couple of balsa model airplane frames built with Duco that are still structurally sound 40 years after they were built.

A little history, for those who don't get invited to dinner parties.

DUCO was the name for a range of nitrocellulose product from DuPont. When you hear about a colour called Duco in a prototype railroad painting diagram for some sort of equipment, they are talking about their cell'y lacquer range for industrial/automotive use.

Dulux, btw, was a range name for a DuPont quick-dry industrial/automotive enamel, so that famous "Dulux Gold" that the decal guys label their lettering sets is really a misnomer taken from a misread of prototype railroad painting diagrams. Dulux referred to the paint type (as does Duco) on the diagram, not some specific shade of gold or yellow.

Back to point, Duco cement originally was a nitrocellulose cement, a product made in a similar enough manner to the paints such that it carried that same type-name. It was a better cement for wood modelbuilding back in the day. I have aircraft models still tight after decades, stronger than the Testors wood cement and much more stable over time than the Goo of that era.

Both Duco as a paint range and as a cement still exist, but are marketed by folks other than DuPont. I have no idea what their chemical and physical makeup is today.

[Tom Dempsey]

The stuff I'm using is marketed as a Devcon product. So far, it seems to be a great adhesive for cardstock to wood. I guess we shall see how it works over time. I also used it to re-adhere age hardened little rubber feet to my mother's "marble" cutting board, seems to be working great there too.

I'm repairing some electronic gadget for my MiL that's made out of some sort of vinyl or some other soft plastic - so far, nothing will touch it. Next up, J-B Weld.

Have you tried CA and Walther Goo yet???

That was the 3rd thing I tried and it failed, although I had trouble cleaning it off the one part.

Rufus,
My eyes will not focus on your avatar photo.
Would you enlarge or explain it for me?
