  • Step 4: Curing the Resin

    • Allow the resin to cure fully before moving the mold. Handling a partially cured resin may cause it to shift and leak.

5. Fixing Poorly Set or Soft Resin Keychains

When your resin keychain is still soft or bendable after curing, it could indicate that the resin hasn't properly set. Below is a quick guide on how to address the issue:

ProblemPossible CausesSolution
Soft Resin Keychain- Incorrect resin-to-hardener ratio- Mix the resin and hardener thoroughly according to instructions.
