Powder Coating Capabilities
Powder coating is a dry finishing process where finely ground particles of pigment and resin are electrostatically charged and sprayed onto a grounded metal surface. The coated part is then heated in a curing oven (typically 350-400°F for 10-20 minutes), where the powder melts and flows into a smooth, durable finish. Powder coating produces a thicker, more uniform coating than conventional liquid paint, with excellent adhesion, impact resistance, and corrosion protection. It is more environmentally friendly than liquid paint because it contains no solvents (VOCs) and overspray can be recycled. Powder coating is the most popular finish for metal fabrications, furniture, automotive parts, and industrial equipment.
