Compared with the solvent coating for coil,it is with high usage,anti-scratch performance and environmental-friendly, no VOC exhaust, energy-saving, doesn’t need the roller coating and be cleaning,has advantages of extraordinary T-bend and MEK at the meantime.

1.Special powder coatings for steel coil and color pre coating plates are not easy to scratch and can guarantee good leveling performance under thin coating. This product is not only with excellent weatherability, extraordinary T-bend, anti-scratch performance,but also with brilliant resistance of organic solvent.

2.Special powder coatings for aluminum coil and color pre coating plate which with good leveling, excellent salt spray resistance performance, extraordinary T-bend and anti-curing performance, also has brilliant T-bend and impact performance even after low-temperature impact.

Product Application:

1.It can be applied in coil color pre coating plate including steel&aluminum coil color pre coating plate.

2.It can be designed to be 30m/min-100m/min fast spraying speed according to your requirements.

3.We can design the smooth, wrinkle, orange peel texture, sand texture, snowflake texture and silver powder etc according client’s requirements.

Application Range:

For its convenient application,high intensity, easy to clean and anti-impact performance etc, our product can be applied to steel coils and pre coating plate, for example, plant, house building precast piece, roof, wall,retail booth,container,isolated column,counter and door frame etc.

This product is also suitable for high decorative hardware surface coating for outdoor high-end metal furniture, industrial electric application, metal craftwork, lockset and audio etc.

Types of powder coating

Powder coatings can be categorized by resin system (epoxy, polyester, hybrid, polyurethane), appearance (smooth, texture, hammer, metallic, pearlescent), or performance level (anti-corrosion, heat-resistant, UV-resistant, architectural grade, automotive grade).

Powder coating colours and effects

Powder coatings offer thousands of colors in gloss, matte, satin, metallic, candy, texture, wrinkle, hammer tone, wood grain, fluorescent, and other custom effects. Special powders can create soft-touch, anti-scratch, anti-fingerprint, or anti-graffiti surfaces.

Powder coating process

The process generally includes surface pretreatment (degreasing, phosphating, chromating, sandblasting), drying, electrostatic spraying, curing in an oven, and cooling. A well-controlled pretreatment and curing process ensures strong adhesion and long service life.

Powder coating benefits

Powder coatings are environmentally friendly, solvent-free, and produce minimal waste. They offer excellent corrosion resistance, weather durability, mechanical strength, and uniform film appearance. The coating is tough, impact-resistant, scratch-resistant, and has a long lifespan.

Applications for Powder Coatings

Powder coatings are widely used in appliances, aluminum profiles, architectural components, automotive parts, bicycles, furniture, outdoor equipment, machinery, electrical cabinets, pipeline systems, and general industrial and consumer goods.

FAQ

What is Powder Coating?

Powder coating is a dry finishing technology where finely ground powder is electrostatically sprayed onto a metal or non-metal surface and then cured at high temperature. After curing, the powder melts into a continuous, durable, and decorative coating layer.

What does powder coating do?

Powder coating protects the substrate from corrosion, weathering, chemical attack, and mechanical wear. It also provides decorative appearance with rich colors, gloss levels, textures, and special effects.

Is powder coating better than paint?

In many industrial applications, powder coating outperforms liquid paint. It forms a thicker and tougher coating, resists corrosion and chemicals better, and does not contain VOCs. It also provides excellent consistency and cost-effective mass production.

Why is it called powder coating?

It is called powder coating because the coating material is a solid powder instead of a liquid paint. The coating is formed by melting and curing powder particles under heat.

What are the different types of powder coating?

Powder coatings include several families depending on resin chemistry:

• Epoxy powders

• Polyester powders

• Epoxy-polyester hybrid powders

• Polyurethane powders

• Acrylic powders

• Fluorocarbon (PVDF) powders

Each type has its own performance features such as corrosion resistance, UV resistance, chemical resistance, outdoor durability, or decorative properties.

Which material is used in powder coating?

Powder coatings are based on thermoset or thermoplastic resins combined with pigments, curing agents, fillers, additives, and in some cases metallic or effect particles. Common substrates include steel, aluminum, galvanized metal, MDF, and certain heat-resistant plastics.

How long will powder coating last?

The lifespan depends on powder type, film thickness, application method, pretreatment, and service environment. Indoor coatings can last more than 10–20 years. High-grade outdoor polyester or fluorocarbon powders can last 15–25 years or longer under UV exposure.
