Powder coating stands as a hallmark in the modern painting and coating industry, revolutionising how we approach surface finishing for a wide array of products. Its rise to prominence owes much to its efficiency, durability, and environmental friendliness compared to traditional liquid paints. In this comprehensive exploration, we’ll delve into the intricacies of powder coating, its composition, process, and how it differs from other painting methods. We’ll also touch on the role of industry leaders like AkzoNobel in providing high-quality powder coatings, culminating with insights into how NSP Coatings effectively utilises these products to deliver outstanding results.

Understanding Powder Coating

What is Powder Coating?

Powder coating is a dry finishing process used extensively to create a high-quality, durable finish on metals and various substrates. Unlike traditional wet paint, powder coating involves applying a dry powder that doesn’t require a solvent to keep the binder and filler parts in a liquid suspension form.

Composition of Powder Coating

The powder used in powder coating typically consists of a mixture of polymer resin systems, pigments for colour, levelling agents, flow modifiers, and other additives. These ingredients are melt-mixed, cooled, and ground into a uniform powder, resembling baking flour in consistency.

The Powder Coating Process


The process begins with the preparation of the parts to be coated. This typically involves cleaning and sandblasting to remove any impurities, oils, or old paint, which helps achieve a smoother and more consistent finish.


The application process involves an electrostatic spray deposition (ESD) system. Here, the powder is charged electrostatically and sprayed onto the grounded substrate. This electrostatic charge causes the powder to cling to the surface, ensuring even coverage.


Once applied, the parts are moved into a curing oven. The powder melts and fuses into a smooth coating in the heat of the oven. This curing process creates a high cross-link density in the polymers, resulting in a tough and durable finish.

Comparing Powder Coating to Other Painting Processes

Environmental Impact

Powder coating is more environmentally friendly than conventional liquid paints. It contains no solvents and emits negligible volatile organic compounds (VOCs), making it a safer choice for the environment and the workers involved in the process.

Efficiency and Durability

The finish from powder coating is typically thicker and more uniform than that achieved with liquid paint. It’s also more resistant to chipping, scratching, and other wear and tear, making it ideal for products subjected to harsh conditions.

Aesthetic Versatility

Powder coating offers a range of textures and finishes, from smooth and glossy to matte and textured. The range of colours available is virtually limitless, with excellent colour retention properties.
