At DB Sheetmetals, we understand the importance of a flawless finish. That’s why we offer exceptional powder coating services, guaranteeing a durable, high quality aesthetic, whatever your sheet metal project entails. In this blog post we’ll delve into the process of powder coating and how we ensure a top quality finish every time.
The Magic Behind the Powder
Unlike traditional paint, powder coating utilises a dry, finely ground powder made from polymer resins, curatives, pigments, and other additives. This mixture is carefully combined, cooled, and milled into a flour-like consistency, ready to transform your metal surfaces.
Preparing for Perfection
Before the powder coating process begins, precise preparation is carried out to ensure a flawless bond. Our team carefully clean and degrease the metal using a phosphate wash. This removes any dirt, grime, or rust and also neutralises the metal’s surface for optimal powder adhesion.
The Power of Attraction
We utilise a cutting-edge technique known as electrostatic spray deposition (ESD). This involves a high-tech spray gun that electrostatically charges the powder particles. These charged particles are then naturally drawn to the grounded metal surface, ensuring a uniform coating.
Curing for Durability
With the powder accurately applied, the curing process solidifies its protective qualities. Inside our curing ovens, the metal undergoes a heat treatment. This heat triggers a fascinating chemical reaction within the powder, causing it to melt and form long, interconnected molecular chains. These chains create a dense, highly cross-linked structure, the secret weapon behind the exceptional durability of powder coated surfaces.
