EPON 8281

EPON™ Resin 8281 was developed for use in formulating highly filled compounds, particularly those with high levels of silica-type fillers. This resin allows the formulator to compound materials suitable for use in a wide variety of products, including adhesives, electrical encapsulants and molding compounds, tooling compounds, and most construction end uses. Benefits include:

  • Excellent resistance to pigment and filler settling
  • Low saponifiable chlorine level
  • Superior resistance to foaming under vacuum
  • Viscosity stability comparable to other conventional liquid EPON Resins

Processing/How to use

General Information Formulations using EPON Resin 8281 meet the requirements of the electronics industry for electrical and dimensional stability, high physical strength, excellent chemical resistance and good electrical properties Filler Settling Characteristics EPON Resin 8281 exhibits superior resistance to filler settling. In the most severe test, 72 hours at 60 °C, EPON Resin 8281 exhibited no settling of filler. This was measured by incorporating 50% by weight silica filler, under high shear conditions, into EPON Resin 8281. After evacuating the entrapped air, the mixture was placed in a 60 °C oven for 72 hours. The mixture was removed from the oven and by use of a metal stirring rod, tested for any filler build-up on the bottom or sides of the container.
