Product Description

DK15EG-05 Black is an epoxy based coating powder developed for the insulation of motor armatures and stators. It offers cut-through temperature resistance and is flex-fuel (unleaded gasoline and methanol) resistant. DK15EG-05 Black is designed to be applied by an electrostatic fluid bed process, offering a fast cure in an induction coil curing process. Particle size is tailored to provide low dusting levels.

DK15EG-05 is flex-fuel (gasohol, gasoline/ethanol blend) resistant, Class F-rated epoxy powder coating for slot insulation of automotive fuel pump motor armatures and stators. It works extremely well for both AC and DC electric motors, including those used for in-tank fuel pumps. The coating provides superior flex fuel resistance, edge coverage, and high impact strength. High cut through temperature serves to protect the motor even at high operating temperatures. DK15EG-05 is designed for electrostatic fluid bed application, and DK15EG-05 is tested and qualified for UL EIS 1446 155°C (Class F) rating.

DK15EG-05 is available in both black and green color. It is black in color, though DK15EG-05 Green is the green color version of DK15EG-05 Black.  Both versions have been used for over 20 years by major manufacturers of automotive enclosures, fuel pumps, windshield wipers, seat adjusters, and other, DK15EG-05 provides a smooth surface appearance with high edge coverage. Particle size is optimized for high productivity on an electrostatic fluidized bed coating process including Braun Sondermaschinen.

Advantages of DK15EG-05 for Slot Insulation

  • Flex-fuel resistant, suitable for exposure to automotive fluids
  • A high pickup powder, it provides high productivity on Braun Sondermaschinen and other electrostatic fluidized bed machines
  • Permits the use of more copper in the slots allowing for smaller, higher-power motors
  • Reduced copper waste compared to slot liners since the winding does not need to go up and over the liner
  • Excellent moisture resistance, even in high temperatures and corrosive conditions
  • A high-productivity coating powder, used for decades in the manufacture of fuel pump assemblies

Typical applications and uses of DK15EG-05 Black or Green include:

  • Slot Insulation of AC and DC Motor Armatures
  • Slot Insulation of Stators
  • Slot Insulation of Motor Armatures in Fuel Pump Motors
  • It has also been tested successfully for hairpin coating of 400V electric motors

Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Shelf Life
Shelf Life
Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties.

It differs vastly per product and it is based on temperature and storage conditions.

The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.
Shelf Life @ 15°C 12 months

Dielectric Strength
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.

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 25 sec
Glass Plate Flow
Glass Plate Flow
Glass plate flow determines the flow distance of thermosetting epoxies, resins or coating powders on a smooth inclined glass surface in a certain time and temperature.

This value is the distance in millimetres from the upper point of the original position of the pellet to the point of extreme flow.

Typically measured at 150°C but please check the TDS for more info

UL 94 Rating
Flammability rating classification.
It determines how fast a material burns or extinguishes once it is ignited.

HB: slow burning on a horizontal specimen; burning rate less than 76 mm/min for thickness less than 3 mm or burning stops before 100 mm
V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole.
