Product Description

DK15-0463 is an epoxy-based coating powder developed for the insulation of low-voltage busbars. It offers improved moisture resistance and dielectric strength along with a smooth surface appearance. The particle size distribution is optimized for use in large fluid bed coating operations. DK15-0463 has a UL Relative Thermal Index (RTI) rating of 130°C, making it ideal for applications requiring high thermal stability. Used for over 20 years by major power distribution companies for low-voltage outdoor bus bar applications, DK15-0463 provides a reliable coating with high edge coverage. The fusion bonded coating is smooth, tough, and moisture-resistant for applications up to 600V. DK15-0463 is UL recognized Particle size is optimized for the fluidized bed coating process.

Advantages of DK15-0463 for Busbar Coating

  • Excellent bed life—so important for large busbar coating operations
  • Excellent moisture resistance, even in high temperatures and corrosive conditions
  • Suitable for both copper and aluminum busbar coating
  • Smooth surface allows closer bar spacing in busway
  • An extremely reliable coating powder, used for decades in the power distribution industry

Typical applications and uses of DK15-0463 Black include:

  • Low Voltage (600V) Copper, Aluminum and Brass Busbars
  • Outdoor busbar applications
  • Switchgear Equipment for Power Distribution

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
Electrical Properties
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.

Volume Resistivity
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.

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 48 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
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.
5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole

Curing Conditions
Curing Schedule
Curing Schedule
Curing schedule is the time and temperature required for a mixed material to fully cure. While this applies to materials that cure with heat, there are also other materials that can be cured with UV.

Even though some materials can cure on ambient temperatures, others will require elevated temperature conditions to properly cure.

There are various curing schedules depending on the material type and application. For heat curing, the most common ones are Snap cure, Low temperature cure, Step cure and Staged cure.

Recommended cure type, schedule, time and temperature can always be found on the Technical data sheets.
Cure Temperature 230 °C
