GPE-221

A cycloaliphatic, diepoxy functional compound, GPE-221 is the combination of aliphatic backbone, high oxirane content and no halogens provides resins low viscosity, weatherability, low dielectric constant and high-cured Tg properties. GPE-221 can be cured with polyacids, anydrides or UV initiators to give optically clear resins and coatings high-heat distortion.

Applications

  • Electrical and electronic component encapsulation
  • Radiation-curable inks and coatings
  • Electrical-insulating varnishes
  • Electrical-resin porcelains
  • Insulating sealants for semiconductors
  • Transparent insulating sealants for optoelectronics
  • Acid scavenger for vinyl-based transformer fluids and lubricating oils
  • Filament winding for aerial booms and antennas
  • Viscosity modifier for Bisphenol A epoxies in tooling compounds
  • Manufacture of plastic embedding kits for electron microscopy
