BetterBond's TC-20™ is the ultimate high-solids, fast drying, and non-flammable adhesive for copper veneer. TC-20 creates a permanent bond to a variety of substrates including MDF, particle board, plywood, and other porous surfaces. We have thoroughly tested and tortured dozens of copper sample panels with TC-20 and the results have been outstanding!
Tip from Joe:
Don't forget a glue roller. It's worth every penny.
This item can not be shipped outside of the USA and Canada.
In a well ventilated area, thoroughly wash the back side of the copper with water or acetone using a steel wool or synthetic steel wool (Scotch-Brite) pad. Apply TC-20 to the porous substrate with a glue roller or short nap paint roller. Set the copper veneer onto the substrate. If necessary, apply painter's blue tape over the edges of the copper to prevent movement. Clamp the surface for 45 minutes using a flat piece of plywood and plenty of weight on top (books, tools, wood, etc). A vacuum press will also work very nicely.
TC-20 is not suitable for exterior projects.
Allow an additional 90 minutes of curing before machining. Not for use with copper containing zinc or copper which has been treated with a protective or gloss-enhancing chemical or process.

I have tried epoxy, gorilla glue, custom-made silicones just for copper, etc., and TC-20 works way better than these. I'm really glad I tried it.

Joe asked me to write my two cents on this glue so here goes.
I work for an elevator repair company in New York. Most of our clients are up scale apartment buildings and offices. We have been installing copper veneer as trim and accents on the interior panels of each elevator cab for over 10 years. I've had my share of horror stories of delamination and repair work is not easy once the unit is installed.
Recently I tried the TC20 glue on a whim. We were using an industrial grade contact adhesive previously. I honestly didn't think a "retail" glue would work very well. I found this to be untrue. The TC20 is excellent. We ended up buying so much of this adhesive that we had to convince Joe to offer it in a gallon size, which he promptly obliged.
It's a bit expensive but you get what you pay for. Since we've began using this one, I have yet to be called back on a delamination repair.

This is not much of a review. I really just wanted to mention that it does take 12 hours to fully harden. After 2 hours, I tried removing the copper sheet and found that it would lift off with some pulling. This was of course disappointing but a day later I found the bond was like epoxy. Its never coming off now. This is a great product and it's also great because it doesnt have the stink of other copper adhesives.

I am an artist and I paint on copper panels that I make myself. I've tried YES! paste (horrible!), epoxies, and Gorilla glue during the construction of over 50 panels. None of the glues I tried were any better than poor and some (gorilla glue) caused random problems.
I tried your TC-20 last night and it worked perfectly, easily and quickly. It's a great product and I'm ordering more.
