Product Description


TC-20 Copper Adhesive

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!

Shelf Life: 12 Months

Features:

  • Fast Drying - Requires only 45 minutes of clamp time
  • Industrial Strength - Dries to a rigid film
  • Environmentally Safe - Contains no V.O.C.'s and is 100% solvent free
  • Ready to Use - No mixing required
  • Easy Clean-Up - Cleans up with water while wet
  • Heat Resistance - Up to 150° F
  • Very High Coverage - Get up to 32 square feet of coverage per pint or approximately 256 square feet per gallon
  • Highly Versatile - Bonds copper veneer to almost any porous material including MDF, particle board, or plywood

Directions:
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 while the adhesive is still wet. 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.

Allow 90 minutes of curing before machining. Full bond strength takes place after 24 hours.

TC-20 is not suitable for exterior projects. Not for use with copper containing zinc or copper surfaces which have been treated with a protective or gloss-enhancing chemical or process. Always test this adhesive on scrap material to determine its suitability for the project at hand.

Tip from Joe:
Don't forget a glue roller. It's worth every penny.


Freeze Protection Current Status: Optional
This adhesive can not be allowed to freeze. We have implemented a procedure using thermofoil bubble wrap and environmentally safe warming packs to protect this adhesive from freezing in transit. Freeze Protection is mandatory when the temperature drops below 32° F at our warehouse in Maryland. Freeze Protection is optional when the Maryland overnight low temperature is above 32° F for more than 72 hours. No orders with the freeze protection option will be shipped on Fridays.

When Freeze Protection is optional, customers may select freeze protection or decline this service based on their own assessment of the temperatures between Maryland and the delivery area. No refunds or replacements will be offered if the adhesive freezes in transit and the customer has declined the freeze protection option.

Will TC-20 bond thicker copper veneers?
As long as the bonding surface of the copper is free of surface contaminants, finishes, and coatings then TC-20 should bond with no problem. Always test a scrap first and then move on to the full size project.

What should I do if I just bonded some of your copper veneer to a piece of plywood and it's not sticking after 90 minutes?
This adhesive needs a full 24 hours to cure. If you "test" the panel before that time and try removing the copper, you will find the bond has not cured. It absolutely must have 24 hours before you judge the quality of the bond. I've yet to hear of a failure after the 24 hour bond time.

Does this adhesive work like contact cement?
This adhesive does not work like contact cement. The bonding and curing take place partly through an evaporative process.

Can this adhesive be used outdoors or in any type of wet environment?
TC-20 is not suitable for areas that will be exposed to water. Continuous exposure to water will cause this adhesive to soften and lose its bonding strength.

What is the vicosity of TC-20 glue?
It is a bit thinner than standard yellow woodworking glue.

What is the shelf life of this adhesive?
Twelve months.

Can this adhesive be used to bond one copper surface to another?
TC-20 requires one of the bonding surfaces to be porous so it will not bond copper to copper or to any other non-porous surface.

Does TC-20 have copper particles in it?
There is no reason to put copper particles in this adhesive since it would not positively affect the quality of the bond strength.

    Excellent adhesive for bonding copper to wood. Easy to use and cleanup too. I highly recommend this to anyone using copper veneer.

    This is the ONLY product to use if you are bonding copper to a surface. Though it is a little bit difficult to find, Veneer Supplies only carries the best products....items you don't find in the big box stores. These products, especially TC-20, are far superior, give better results, and will save you both time and money. Shipping is fast and the service is excellent!

    I have dealt with Veneer Supplies for several years now and have had excellent results. This was the only supplier that had a copper glue that I trust.


  4. Worked Flawlessly

    I was fortunate to find this website through a Google search for an adhesive to bond copper sheet to MDF. Joe's web site is very informative. After investing in more than 100 square feet of patina copper for an accent wall, I had mistakenly purchased contact cement for the project.

    Joe and Christine shipped product to me quickly and their TC-20 has worked perfectly! Trimming the copper sheet with a laminate trimmer (Bosch hand router) worked flawlessly, the TC-20 allowed no delamination.


  5. Review fom West Lafayette, Indiana

    I've done a lot of research and have tried contact cement to adhere copper but it doesn't compare to this. This glue is MUCH easier to work with and has great adhesion. I had problems with the corners coming up while routing the edges of the copper veneer when I used contact cement. I haven't had any such problems with this stuff. It's great. No odor, unlike contact cement. It also has a much more open working time.

    Honestly, if you're paying the money for a copper veneer then this price shouldn't scare you away. Don't cut corners and ruin a project. This stuff is well worth it.

    I have used this for copper and concur with all other reviews, but have a project requiring bonding a sheet of .020 brass. Since I had some left over TC-20, I laminated a scrap of brass stock to a scrap of plywood. I tried to peel off after normal cure time, and am simply peeling the plywood apart. The wood to brass bond will not give! Appears to work just as well with brass!


  7. Way Better...

    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.


  8. Many Tests - This One Works!

    Review by Scott B.

    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.


  9. A Last Minute Surprise - Good Product

    Review by Miles Elsin

    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.


  10. Great Product And I'm Ordering More

    Review by RICHARD MURDOCK
    Rating:

    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.

    Thanks,
    RM
