Guide to use

Curing conditions:

200℃/10min; In order to make the coating film of the coated object cure evenly and the gloss stable, it is best to make the temperature distribution in the baking furnace uniform; and reasonably control the curing temperature and time according to the situation of the workpiece.

Pretreatment:

The workpiece must be pretreated before spraying, and it must comply with the provisions of Chapter 5 of GB/T 8013.3-2007. The mass of the chromate conversion film should be between 0.4 and 1.0 g/㎡. The time interval between chemical conversion pretreatment and coating should not exceed 16 hours. In principle, coating should be applied immediately after the conversion treatment is dry.

Workpiece hanging:

When hanging the workpiece, hang it reasonably according to the shape and thickness of the workpiece to improve the powdering rate and yield; and pay attention to keeping the spraying system and the surrounding environment clean to prevent different brands of powder coating from mixing and affecting the surface effect of the coating.

Powder spraying:

Choose reasonable process parameters, control the voltage, air pressure and powder output. The powder spraying environment should preferably have a temperature and humidity control system. The optimal powder spraying temperature is 15-25℃, and the relative air humidity of the powder spraying room is preferably 45%-55%; in addition, the proportion of recycled powder should be controlled to ensure the color stability of the product.

The recommended coating thickness is 60-80um, otherwise it will affect the performance of the coating.

During the film formation process, the color will be slightly affected by process conditions such as temperature and thickness. It is recommended that users conduct tests before use to achieve satisfactory results.

Packaging and storage

The outer packaging of powder coating is a hard carton lined with a plastic bag, with a net weight of 25KG and 20KG per box. It should be stored at an ambient temperature below 30℃, and the storage environment should be kept ventilated and dry, and the powder should be prevented from direct sunlight. The location where the powder is stored is not allowed to be close to fire and away from heat sources.

Safety measures

This product is non-flammable and explosive, basically non-toxic, and must not be ingested.

FAQ

1. What is Powder Coating?

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)

2. Benefits of Powder Coating

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.

3. What Temperature to Cure Powder Coating

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.

4. Process for Powder Coating

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

5. How to Spray Powder Coat

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.
