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
  • Very High Coverage - Get up to 32 square foot of coverage per pint
  • 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: Mandatory
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 assessment of the temperatures in 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. You are responsible for selecting the appropriate option based on the temperature forecast in your area.

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.
