What is Powder Coating? Vitarag Chemicals is a prominent metal pre treatment chemicals manufacturer for powder coating. - Powder coating is a type of dry finishing process used to apply a protective and decorative coating to metal (and sometimes plastic or MDF) surfaces. Instead of using liquid paint, powder coating uses a dry powder, which is applied electrostatically and then cured with heat to form a hard, durable finish. * How Powder Coating Works: 1. Surface Preparation Clean the surface using blasting, degreasing, or a chemical pre-treatment (e.g., 3-in-1 chemical). Ensures good adhesion and corrosion resistance. 2. Powder Application The powder (a fine, dry mix of resin, pigment, and additives) is sprayed onto the surface using a powder coating gun. The gun imparts an electrostatic charge to the powder, causing it to stick to the grounded part. 3. Curing The coated part is placed in an oven, typically at 160–200°C (320–392°F) for 10–20 minutes. The powder melts, flows, and chemically crosslinks into a smooth, uniform, and durable film. * Advantages of Powder Coating Durability: Tougher and more resistant to scratches, corrosion, and weather than traditional paint. Eco-Friendly: No solvents or VOCs (volatile organic compounds). Efficiency: Overspray can often be recycled, reducing waste. Aesthetics: Available in a wide range of colors, textures, and finishes (glossy, matte, metallic, etc.). # Powder Coating Remover Chemical Manufacturer.
