In the world of finishing and protecting metal surfaces, powdercoating stands out as a superior method. But what exactly is powdercoating, and what does it do? Let’s dive into the basics of this versatile and durable finishing technique.
What Is Powdercoating?
Powdercoating is a dry finishing process that has become extremely popular since its introduction in North America in the 1960s. It involves applying a free-flowing, dry powder to a surface, which is then cured under heat to form a solid, protective layer. Unlike traditional liquid paint, powdercoating doesn’t require a solvent to keep the binder and filler parts in a liquid suspension form.
How Does Powdercoating Work?
Preparation: The surface to be coated is thoroughly cleaned to remove any dirt, oil, or other contaminants. This step is crucial for ensuring a strong bond between the powder and the metal.
Application: The powder can be applied using an electrostatic spray gun. The gun imparts a positive electric charge to the powder particles, which are then sprayed onto the grounded surface. This creates an electrostatic attraction, ensuring an even coating.
Curing: After application, the coated item is placed in a curing oven. The heat causes the powder to melt and form a uniform, durable “skin” over the item. This curing process usually takes between 10 to 30 minutes.
What Does Powdercoating Do?
Durability: Powdercoating creates a hard finish that is tougher than conventional paint. It is highly resistant to chipping, scratching, and fading.
Corrosion Resistance: It provides excellent protection against rust and other forms of corrosion, making it ideal for outdoor and industrial applications.
Aesthetic Versatility: Powdercoating is available in a wide range of colors and finishes, from glossy and matte to textured and metallic, allowing for extensive customization.
Environmental Benefits: Powdercoating is an eco-friendly option. It emits virtually no volatile organic compounds (VOCs) and the overspray can be recycled, reducing waste.
