Methods & Tips To Store Super Glue or Cyanoacrylate Glue
One of the most common products in a workshop is Cyanoacrylate ester or as it is more commonly called, Super Glue or Cyanoacrylate. Super Glue or Cyanoacrylate adhesive can be a valuable addition to
your toolbox for numerous tasks around your workshop. Here are a few tips for using and storing Super Glue or Cyanoacrylate that will help you make the most of this versatile product.
Most Super Glue or Cyanoacrylate’s have an average shelf life of about 6-12 months once opened. Unopened bottles can be stored in the freezer for an extended period of time.
However, once a Super Glue or Cyanoacrylate bottle is opened and exposed to atmospheric moisture, different storage procedures are required to prevent premature curing in the bottle.
Unopened Super Glue or Cyanoacrylate bottles should be stored in the freezer for the longest shelf life. Before using, allow the bottle to come to room temperature. It would be preferrable to allow the frozen bottle to sit overnight on the bench before using it, to insure that it has reached uniform ambient temperature.
Do not store opened bottles without their caps, unless you live in areas that routinely have very lowhumidity levels year round. Exposure to high humidity can cause premature curing of the Super Glue or Cyanoacrylate in the bottle.
If you purchase your Super Glue or Cyanoacrylate in bulk containers and transfer them into smaller applicator bottles for use, ensure that these bottles are manufactured from polyethylene for best storage results.
Do not store opened Super Glue or Cyanoacrylate containers near your manual pump accelerator bottle. During the summer months, high heat can cause accelerator vapors to leave the pump spray unit, causing premature curing of a nearby CA bottle. Some accelerators are now available in pressurized spray cans. While these are more expensive initially than bulk liquids, over time I have found out that they end up costing less per use than the bulk liquids.
It’s a quite common and frustrating fact that Super Glue or Cyanoacrylate tend to clog the tips of their applicator bottles. If you employ one of the following procedures, you can effectively mitigate this problem.
When you have finished using the Super Glue or Cyanoacrylate , allow sufficient time for the Super Glue or Cyanoacrylate left in the tip to return to the bottle before replacing the cap. Sometimes, a sharp rap on the counter will assist in clearing the tip of the bottle of any uncured Super Glue or Cyanoacrylate . Always cover the bottle with a cloth and wear face and eye protection when rapping the bottle to clear the tip. Wipe the exterior of the tip with paper towels before storing the bottle away.
Do not touch the tip of the bottle onto a surface that has been sprayed with active accelerator, or the accelerator will cure the Super Glue or Cyanoacrylate inside the nozzle. When you have finished using the Super Glue or Cyanoacrylate, simply switch the used tip for a spare clean tip. Place the used tip in a small jar of Acetone until it is needed again.
When another fresh tip is needed, use tweezers to swap the clean tip in the Acetone jar with the used tip. Allow the tip to fully dry before replacing the tip on the Super Glue or Cyanoacrylate bottle. Spare tips can be purchased at most suppliers that sell Super Glue or Cyanoacrylate .
