This series of products uses advanced Bonding technology equipment to produce surface metal powder with brighter optical effects, good metallic luster, no black spots, yin and yang colors, fingerprints and other defects in the coating, high powder application rate, and high utilization rate of recycled powder.
The metal pigment is tightly combined with the base powder, and there will be no clogging of the muzzle during spraying;
The adhesion between the metal powder and the substrate is strong, and it is not easy to fall off during painting:
The recycled powder spraying effect is compatible with the new powder;
The coated metal pigment is not easy to fall off, oxidize, and has no fingerprint defects.
Various wrinkles, metal, pearlescent effects and mixed colors, etc.
Metallic powder coating refers to various powder coatings containing metal pigments (such as: copper gold powder, silver aluminum powder, pearlescent pigments, etc.). Due to its gorgeous decorative effect of the coating, it is very suitable for spraying fitness equipment, furniture, automobiles, etc.
Carton packaging, lined with two layers of polyvinyl chloride plastic bags, net weight of each box is 20kg. Non-hazardous items can be transported in various ways, but should be kept away from direct sunlight, moisture, heat, and chemical substances.
Operators should wear dust masks during use to avoid inhaling dust and minimize long-term contact between skin and powder coating. Paint attached to the skin can be washed with soap.
| Specific gravity | 1.2~1.8g/cm’ (depending on the formulation and color) |
| Particle size | Depending on the purpose, the standard type has an average particle size of 35~40 microns, less than 10 microns powder <10%, and greater than 100 microns powder <0.5%. |
| Storage stability | Bonding metal powder coatings should be stored in a dry, ventilated room below 35°C, and avoid direct sunlight. If stored in an air-conditioned room, the powder must be stored at room temperature or the same (temperature) as the spraying equipment before use to avoid moisture. Under this condition, the powder can be stored stably for 6 months. If it exceeds the period, it must be re-tested. If the result meets the requirements, it can still be used. Note: For low-temperature curing types and powders with light below 40% (60°), the storage temperature should be below 30°C. |

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.
