General Industrial Powder Coating is a finishing process that applies a dry powder to a surface, which is then cured under heat to create a tough, protective layer. Unlike traditional liquid paint, which contains solvents that evaporate during application, powder coating is composed of finely ground particles that can provide a thicker, more even coating.
Understanding the powder coating process involves several steps. Let’s break them down:
Before the powder coating can begin, the surface must be properly prepared. This often involves cleaning and removing any grease, dirt, or old paint. Common pre-treatment methods include sandblasting, acid washing, or using a phosphating solution to ensure optimal adhesion. Think of this step as giving the surface a clean slate to ensure that the powder will stick effectively.
Once the surface is prepped, the powder coating material is applied. There are several methods for doing this, the most common being the electrostatic spray process. In this method, an electric charge is applied to the powder particles, causing them to be attracted to the grounded surface. This results in an even coat that adheres well without the drips and runs often associated with liquid paint.
After application, the coated object is moved to a curing oven. The heat activates the powder, causing it to melt and flow into a smooth coating. This process typically occurs at temperatures around 350°F (175°C) for 10 to 30 minutes, depending on the type of powder used. The result? A hard, durable finish that bonds to the surface.

Once curing is complete, the coated item is removed from the oven and allowed to cool. This cooling process might reveal any imperfections in the coat, and any items that do not meet quality standards can be reprocessed. At this stage, inspections are critical to ensuring that every item meets the necessary specifications.
