Product Description

Class 2 & 3 capable epoxy coating powder for ceramic capacitors/varistors and tantalum capacitors

DK18-05 Gold is a medium-performance, epoxy coating powder developed for Class 2 & 3 capacitors and varistors. DK18-05 has excellent pickup and curing at temperatures as low as 110°C, making it excellent also for tantalum capacitors and other temperature sensitive devices.

DK18-05 has a proven track record, is recognized with a UL 94 V-0 flammability rating, and is available in a wide range of colors.

Applications of DK18-05 Black

DK18-05 has found its way into a wide range of applications due to its wide process window and versatile properties. It is used in passive electronic components including varistors, resistors and inductors. It is also used extensive in thermal fuse applications.

Main Applications

  • Class 2 & Class 3 Ceramic Capacitors
  • Class 2 & Class 3 Ceramic Varsitors
  • Tantalum Capactitors
  • Niobium Capactitors

Product Features & Benefits:

  • Used for more than 20 years on capacitors, varistors, and other passive components

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.

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.
