Product Description

LINQSOL BCP-1522 is a thermosetting coating powder designed for low to medium-voltage busbar and switchgear applications. Once cured, BCP-1522 forms a smooth, durable, and moisture-resistant coating, suitable for operations up to 38 KV. The powder allows for fast and significant coating buildup, which speeds up production cycles. It can be used effectively on both copper and aluminum busbars, creating coatings that are over 200 mil (5 mm) thick.

LINQSOL BCP-1522 also boasts a high UL746B Relative Thermal Index (130 °C), ensuring reliable performance even under elevated temperatures. Its fine particle size (44–210 µm), which is optimized for fluidized bed coating systems, promotes uniform application and consistent coating quality. 

 

Advantages of BCP-1522 for Busbar Coating

  • Suitable for copper and aluminum bar

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 @ 25°C 273 days
Electrical Properties
Arc Resistance
Arc Resistance
ASTM-D495 expresses arc resistance as the number of seconds that a material resists forming a surface-conducting path when exposed to a high-voltage, low-current arc occurring intermittently. Results obtained from a nominal 3 mm thickness are meant to represent the material’s reaction in any thickness.

Breakdown Voltage
Breakdown Voltage
Breakdown voltage is the minimum voltage necessary to force an insulator to conduct some amount of electricity.
It is the point at which a material ceases to be an insulator and becomes a resistor that  conducts electricity at some proportion of the total current. 

After dielectric breakdown, the material may or may not behave as an insulator any more because of the molecular structure alteration. The current flow tend to create a localised puncture that totally alters the dielectric properties of the material.

This electrical property is thickness dependent and is the maximum amount of voltage that a dielectric material can withstand before breaking down. The breakdown voltage is calculated by multiplying the dielectric strength of the material times the thickness of the film.
 38,000 V
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.

Dielectric Constant
Dielectric Constant
Dielectric Constant (k), commonly known as relative permittivity, is a number relating the ability of a material to carry alternating current to the ability of vacuum to carry alternating current.

It determines the ability of an insulator to store electrical energy and is the ratio of electric permeability in vacuum against the electric permeability of a material.

The lower the dielectric constant (κ) and dissipation factor, the less energy is absorbed from an electric field, making it a much better insulator.

It is a dimensionless property that can be affected by various factors such as the
thickness uniformity of a material, insufficient contact between the sample and electrodes, water adsorption and contact resistance.

Dissipation Factor
Dissipation Factor
Dissipation factor is commonly known as loss tangent or tan delta.



It is a ratio of the loss index and the relative permittivity and it measures the inefficiency of an insulating material to maintain energy (that otherwise dissipates in the form of heat). The lower the factor, the better the insulation.

It is the reciprocal of the quality factor and always refers to a specific temperature and frequency.

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 30 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

Additional Information

Storage and Handling

Powder should be stored at 10°C or below, in closed containers. After removal from cold storage, the material must be allowed to come to room temperature in the sealed container to avoid moisture contamination. The suggested waiting time is 24 hours. Please consult our Product Handling Recommendations for Coating Powders. For safe handling information on this product, consult the Material Safety Data Sheet (MSDS).
