Frequently Asked Questions

Q: What type of resin works best with this silicone rectangle mold?

A: This silicone cuboid mold is compatible with most types of epoxy resin, UV resin, and casting resin. Epoxy resin is especially popular for preserving flowers and insect specimens, as it creates a crystal-clear, durable finish that showcases every detail beautifully.

Q: Do I need any special tools to use the wooden support frame?

A: No special tools are required. The wooden support frame is designed to slot around or underneath the silicone mold to keep it stable and upright while you pour resin. Simply set it up on a level surface before pouring for best results.

Q: How do I demold the finished resin piece without damaging it?

A: Once your resin has fully cured (typically 24–72 hours for epoxy resin, depending on the brand), gently flex the silicone mold from the outside to loosen the edges, then carefully peel the mold away from your finished piece. The non-stick silicone surface makes demolding smooth and easy.

Q: Can this mold be reused multiple times?

A: Yes! The high-quality silicone construction is built for repeated use. After each pour, simply clean the mold with warm water and mild soap, allow it to dry completely, and it's ready for your next project.
