The Common Culprits Behind Epoxy Resin Not Hardening

  • Incorrect Mixing Ratio: One of the most critical steps in preparing epoxy resin is measuring and mixing it in the correct ratio. Most systems work on a 1:1 ratio; however, deviations from these proportions can result in a tacky or soft finish.
  • Improper Mixing: Under-mixing can leave parts of the resin and hardener unmixed, leading to uneven curing. Ensure thorough blending to achieve a consistent mixture.
  • Temperature Factors: Epoxy resin requires a specific temperature range to cure correctly. If your workspace is too cold, the chemical reaction might not initiate, causing the resin to remain liquid.
  • Quality of the Epoxy: Using high-quality epoxy resin, such as those provided by ZDS™, is crucial. Low-grade resins may have impurities or incorrect formulations that affect the curing process.
  • Expired Products: All epoxy resins have a shelf life. Using materials past their expiration date can hinder proper hardening.
  • Environmental Humidity: Excessive humidity can interfere with the curing process, especially for certain types of epoxy resin designed for low-humidity conditions.
