First, durability. Powder coating produces a thicker, more uniform layer (60–100 microns) that resists scratches, impacts, and corrosion better than liquid paint, which is typically 25–50 microns.
On upfront cost, liquid paint looks cheaper per liter, but total cost of ownership is often higher: more coats required, longer drying times, and more frequent repainting.
Powder coating is solvent-free and VOC-free, and overspray waste can be recycled. Liquid paint requires solvents, special ventilation, and hazardous waste management that add compliance costs.
Powder coating's limitation: it suits only materials that can withstand oven heat (160–200°C), so it is not ideal for wood or low-density plastics. For metal products, it wins on almost every aspect.
In short, for metal products with medium-to-high production volume, powder coating is almost always more economical over the product's lifecycle. Run the numbers with the SIKKAS team for your specific needs.
