Customer Cases
Powder coating is a dry finishing process used to apply a protective and decorative coating on metal or other surfaces. Instead of using liquid paint, fine powder particles (usually made of polyester, epoxy, or hybrid resins) are electrostatically charged and sprayed onto a conductive surface. The coated object is then baked in an oven, where the powder melts, flows, and cures into a smooth, durable finish.
Key features:
Durable, hard finish
Resistant to scratches, corrosion, and UV
Environmentally friendly (no VOCs)
Powder coating offers several advantages over traditional liquid painting:
Durability: Resistant to chipping, scratching, fading, and wear.
Corrosion Protection: Provides excellent protection against rust and chemicals.
Environmentally Friendly: No volatile organic compounds (VOCs) and minimal waste.
Efficiency: Overspray can be collected and reused, up to 99% material utilization.
Uniform Finish: Smooth, even coating without runs or drips.
Cost-Effective: Single-coat systems can achieve high film thickness, reducing labor and energy.
Aesthetic Variety: Wide range of colors, textures, and effects.
The curing temperature depends on the type of powder used:
Epoxy powder: ~160–200°C (320–392°F)
Polyester powder: ~180–210°C (356–410°F)
Hybrid (Epoxy-Polyester) powder: ~180–200°C (356–392°F)
Typical curing time: 10–20 minutes depending on thickness and oven type.
Always follow the powder manufacturer’s specifications for best results.
The powder coating process usually follows these steps:
Surface Preparation:
Clean the surface thoroughly (remove oil, grease, rust, or dirt)
Methods: chemical cleaning, sandblasting, or phosphating
Pre-Treatment:
Apply a conversion coating or primer if needed to improve adhesion
Powder Application:
Spray the powder using an electrostatic spray gun or fluidized bed
Curing:
Bake the coated object in an oven at the recommended temperature for the powder type
The powder melts and forms a continuous, smooth film
Cooling & Inspection:
Let the coated item cool
Inspect for defects, uniform coverage, and desired thickness
Equipment Needed:
Electrostatic spray gun
Compressed air supply
Powder feed hopper or container
Grounding of the object
Steps:
Ground the object: Ensures the charged powder is attracted to the surface.
Spray evenly: Hold the gun 6–12 inches from the surface, moving in smooth, overlapping strokes.
Apply sufficient powder: Ensure full coverage without excessive buildup.
Cure immediately: Transfer the sprayed item to the curing oven to fuse the powder into a solid coating.
Tips:
Maintain consistent speed and distance while spraying.
Use proper ventilation to reduce airborne powder accumulation.
Test a small area to check film thickness and color before full application.
