EPOXYLITE E6107

Main features

  • Equal-Weight Two-Component Mixing
  • Two-Day Room-Temperature Pot Life
  • VPI and Vacuum Impregnation

Product Description

EPOXYLITE E6107 Hi Temp Epoxy Resin System is a two-component heat-cured impregnation and casting system with a viscous liquid resin and fluid liquid hardener. It is used for VPI, vacuum impregnation, and bench casting of motor armatures, stators, coils, and glass-wrapped electrical or structural components. The components mix at 100:100 by weight. Typical resin viscosity is 18,000 to 28,000 cP, while hardener viscosity is 150 to 400 cP. A staged heat cure develops Shore D 90 hardness together with stated mechanical and electrical insulation properties.

Key features

  • Equal-weight component mixing: The resin and hardener use a 100:100 mix ratio by weight.
  • Extended processing window: The mixed system has a pot life of at least two days at room temperature.
  • Impregnation and casting versatility: The system supports VPI, vacuum impregnation, and bench casting processes.

Applications

  • Impregnation of motor armatures, stators, and coils
  • Impregnation and casting of glass-wrapped electrical and structural components

Thermal Properties
Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.
94 °C
Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
19 kV/mm
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
