Can the SPI-Chem Low Acid GMA be polymerized with heat?
Yes! However, oxygen must be excluded at all times. There are a number of different choices for excluding oxygen, such as sealing the GMA blocks in gelatin capsules, BEEM® capsules, or Micromolds (with one stacked on top to exclude oxygen). Another possibility for those used to using silicone flat embedding molds is to overfill the cavities a bit and then place another identical mold on top; the capillary action will form an effective seal against oxygen. And the mold being used for the top seal still can be used as a mold.
