What is Sheet Powder Coating?
Sheet powder coating refers to the process of applying powdered paint particles electrostatically to surfaces such as metal or plastic sheets. This method is applied using an electrostatic powder gun. Sheet powder coating applications create a homogeneous paint layer on the sheet, providing a durable and aesthetically pleasing surface, supported by various devices.
How is Sheet Powder Coating Applied?
Sheet powder coating is a coating method applied to preserve metal sheets and give them an aesthetic appearance. Our company performs sheet powder coating applications by electrostatically applying powder paints and baking them at a specific temperature to enhance adhesion to the metal surface.
For sheet powder coating, preliminary preparations are carried out. The sheet's surface must be completely clean and smooth to ensure a durable and sturdy coating. Any oil, dirt, and other foreign substances on the metal surface are cleaned using an alkaline-based solution. To prevent oxidation and corrosion on the sheet surface, it is washed with an acid-based solution. After the washing process, rinsing is carried out. The sheet is thoroughly rinsed with water. To protect metals against rust in sheet powder coating, a phosphate coating is also applied. However, a final rinse is performed after phosphate coating. After all these processes, the sheets are heated and dried to evaporate the water.
In electrostatic powder coating processes, the sheet is painted with an electrostatic powder gun. The powder gun imparts a negative charge to the paint particles, and these negatively charged particles adhere to the positively charged sheet. High voltage is used to enhance the adhesion of the paint particles to the sheets.
Painted sheets are baked in a special oven to melt the paint and adhere it well to the metal surfaces. During baking, which is generally done at a temperature between 180°C and 200°C for a specified period, the powder paint undergoes polymerization. This results in a durable, hard, and smooth surface. After the baking process, the sheet is cooled naturally or in a controlled environment. Finally, the quality of the painting is checked, and the product is packaged. Powder coating has many advantages over traditional liquid paints, including durability, longevity, and environmental friendliness. Powder coating applications that provide excellent protection for the surfaces they are applied to are carried out by our company, Fiber Metal.
Sheet Powder Coating Prices
Sheet powder coating prices vary depending on many factors. The dimensions of the materials to be painted and the type of paint used are some of the factors affecting sheet powder coating prices. Labor costs, as well as the complexity of the work, also cause variations in sheet powder coating prices. The type of material, size, details, color, and type of coating requested also affect the prices, making it impossible to provide precise information on sheet powder coating prices. For accurate information on sheet powder coating prices and to receive the best-priced services tailored to your project's requirements, you can contact our company, Fiber Metal.
What are the Application Areas of Sheet Powder Coating?
The application areas of sheet powder coating vary, and it is widely used in many fields. Industrial applications are at the forefront, followed by decorative applications where sheet powder coating processes are applied. Automotive parts, construction materials, lighting products, electronic devices, outdoor or indoor furniture, and accessories are among the areas where sheet powder coating is preferred.
