What mold materials are compatible with EcoPoxy’s casting resins?

If you choose to build a mold, we recommend using melamine, medium density fibreboard (MDF), or smooth plywood for the base and walls. Visit EcoPoxy’s support website for the tutorial on how to build your own casting mold. If you are wondering about other materials for your mold surface, see below for a list of materials that epoxy will and will not stick to.

Epoxy will stick to:

  • Wood
  • Glass
  • Aluminum

Epoxy will not stick to:

  • EcoPoxy Epoxy Mold Release Tape
  • High Density Polyethylene (HDPE)
  • Teflon
  • Polyethylene
  • Polypropylene
  • Nylon
  • Mylar
  • Silicone

Pre-made molds are available from epoxy or other woodworking stores. Follow manufacturer instructions for surface preparation prior to casting.
