How to Remove Bubbles From Epoxy

Epoxy resin is used for many different purposes. It is used as an adhesive to bind objects and different types of material together. It is also used to waterproof different types of surfaces to prevent water damage from occurring. Pockets of air can develop in epoxy coating and cause the epoxy to not cure properly or provide adequate protection from water and moisture. There are several ways to eliminate the air bubbles in epoxy.

Things You'll Need

Syringe
Centrifuge
Oven-safe container
Oven

Instructions

- 1
  Draw the epoxy up inside a syringe. Place the syringe on a table, countertop or other type of flat surface, making sure that the tip of the syringe is tilted up so that the smaller bubbles can escape from the epoxy and out the syringe.
- 2
  Push up on the syringe plunger to help push out some of the bigger air bubbles in the epoxy. Stick the cap back on the syringe to prevent the epoxy from squirting out while you use the centrifuge.
- 3
  Place the syringe containing the epoxy into the centrifuge. Set the centrifuge run at 3,000 RPMs for around eight to ten minutes. This should finish removing the rest of the air bubbles inside the epoxy.
- 4
  Take some of your epoxy and place it into a container that is safe to use in an oven. Make sure the container is made out of material that will not melt while it is baking in the oven.
- 5
  Set the oven temperature at 100 degrees Fahrenheit. Set the container with the epoxy in it inside the oven. Allow it to stay in the oven for around eight to ten minutes. Remove the container and give the epoxy a few minutes to cool off.
