Epiform F-335M | Green Armature coating powder

Main features
  • Motor Armature coating
  • Good heat resistance
  • Multiple application methods

Product Description

Epiform F-335M is an insulating epoxy powder resin that is engineered to protect and insulate motors and more specifically motor armatures. It offers high edge coverage good heat and electrical resistance and good adhesive strength. This product can be used with a Simple and Electrostatic Fluidised bed while also applicable through hot or electrostatic spray coating, making it a very flexible material for multiple application methods.

Epiform F-335M is designed for slot insulation of motor armatures. It offers excellent electric resistance (2x1016 Ω/cm) and breakdown voltage (18 kV/0.5mm) and has an average particle size of 60um.

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.

Thermal Properties
Gel Time
Gel Time
Gel time is the time it takes for a material to reach such a high viscosity (gel like) that it is no longer workable.

It is usually measured for different temperature conditions and even though it does not refer to full cure it is advisable to never move or manipulate the material after it reached its gel time since it can lose its desired end properties.
Gel Time @ 160°C / 320°F 13 sec
Glass Transition Temperature (Tg)
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.

The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
130 °C
