Electrostatic Powder Coating

Electrostatic powder coating provides a durable, consistent finish for metal components, combining efficient powder application with strong adhesion and long-term protection. At Frederick Cooper, we use electrostatic powder application as part of our comprehensive coating process, delivering high-quality finishes for manufacturers across a range of industries.

With experience dating back to 1879, we provide an end-to-end service covering preparation, coating, curing and inspection. Whether you require high-volume production or a more bespoke solution, our experienced team can develop a coating process around your component, specification and end-use requirements.

What Is Electrostatic Powder Coating?

Electrostatic powder coating is a method of applying dry powder to metal components using an electrical charge. The charged powder is attracted to the grounded component, helping create an even and consistent coating before the part is cured in an oven.

The process produces a durable, high-quality finish and can be used across a wide range of metal components and applications.

How Does Electrostatic Powder Coating Work?

Achieving a high-quality powder-coated finish involves more than simply applying powder to a component. Surface preparation, application, curing and inspection all play an important role in the final result.

1. Component Preparation

The surface must be suitably prepared before powder is applied. Depending on the substrate and specification, this can include cleaning, degreasing, pre-treatment, shot blasting, sanding or other preparation processes.

Our metal preparation services allow us to prepare a wide range of substrates before coating, helping ensure good adhesion and a consistent finish.

2. Masking

Where required, threads, bores, mating faces and other areas can be masked to prevent powder from being applied to specific surfaces.

This is particularly important for components that need to meet precise dimensional or assembly requirements.

3. Electrostatic Powder Application

The powder is applied to the prepared and grounded component using specialist electrostatic spray equipment.

The electrical charge causes the powder particles to be attracted to the component, helping provide consistent coverage across the surface.

The application process is carefully controlled according to the component, powder specification and required finish.

4. Curing

Once the powder has been applied, the component is transferred to a controlled curing oven.

Heat causes the powder to melt and cure, creating a continuous and durable coating. Correct control of curing temperature and time is essential to achieving the required coating performance and appearance.

5. Inspection

The finished component is inspected to ensure it meets the required specification.

At Frederick Cooper, quality control is integrated throughout our production process, with finished products checked before dispatch.

Benefits of Electrostatic Powder Coating

Electrostatic application offers several advantages for manufacturers looking for a reliable and consistent coating process.

Consistent Coverage

The electrostatic charge helps powder particles adhere to the grounded component, supporting an even coating across the surface.

Durable Protection

Once cured, powder coating creates a tough finish designed to withstand handling, wear and environmental exposure.

Efficient Application

The electrostatic process helps improve powder transfer to the component, making it an efficient method for coating metal parts.

Wide Choice of Finishes

Powder coating is available in a broad range of colours and finishes. At Frederick Cooper, we can provide colour options including RAL, Pantone and BS, with finishes ranging from smooth to textured and matt.

Suitable for High-Volume Production

Electrostatic powder coating is well suited to repeat production, making it an effective option for manufacturers requiring consistent finishes across large quantities of components.
