Brief: Discover the LE/LH 8214F Sealant Casting Epoxy Resin, a high-quality outdoor epoxy resin designed for medium and high voltage transformers casting process. This two-component system offers excellent dielectric and mechanical properties, making it ideal for vacuum casting applications.
Related Product Features:
  • Two-component epoxy resin system, liquid at room temperature, suitable for vacuum casting process.
  • Lower curing shrinkage ensures dimensional stability of the end product.
  • Excellent processing performance with high dielectric and mechanical properties.
  • Modified BPA type epoxy resin (LE-8214F) and modified carboxylic anhydride liquid hardener (LH-8214F).
  • Thermal conductivity ranges from 0.8-0.9W/mk, ensuring efficient heat dissipation.
  • High dielectric strength of 30kV/mm, suitable for medium and high voltage applications.
  • Low water absorption (0.10-0.20% by wt. at 23℃ ×10days), enhancing durability.
  • Complies with ROHS and REACH safety regulations, ensuring environmental and safety standards.
FAQS:
  • What is the shelf life of the LE/LH 8214F epoxy resin system?
    The shelf life is normally 12 months when stored in tightly sealed and dry original containers at 6~35℃. After this date, the product may be reanalyzed to confirm its validity.
  • What are the recommended processing parameters for vacuum casting?
    The recommended processing parameters include premixing at 70°C for 2 hours, final mixing for 15-30 minutes, feeding at 100°C for 8 hours, mold temperature at 105°C for 4-6 hours, and post-curing at 130°C for 10 hours.
  • What applications is the LE/LH 8214F epoxy resin system suitable for?
    It is suitable for medium and high voltage electrical insulation products such as dry type transformers, 10-66kV current and voltage transformers, and other high voltage switch insulation parts.
