What is Powder Coating: All You Need to Know About
Powder coating is a free-flowing dry finishing process. This process replaces liquid suspension with thermoplastic or thermoset powder material. The supplier applies the material to the desired surface, melted, and left aside to dry and harden into a durable coating.
Alternatively, the coating can be applied by dipping preheated parts into a powder material. For this purpose, a fluidized bed that fuses every corner of the part with paint material. In both cases, you get a surface with a smooth and protective finish, which is much harder than traditional paint.
Typically, the powder is used to coat metals but also has other applications. Powder-coated surfaces are also more resistant to scratching, fading, chipping, and wearing, unlike other finishes. You can have the custom colors for your powder coating products.
The Benefits of Powder Coating
- Highly durable: The long-lasting and durable finish that is both protective and decorative.
- Impact resistance: It increases parts’ resistance to moisture, chemicals, impact, and extreme weather conditions. Thus, it is suitable for high traffic and abrasive areas.
- Eco-Friendly: Powder coating does not contain harmful solvents or releases negligible amounts of VOC to the atmosphere.
- Minimal Health Hazard: Causes no breathing problems or irritation to the skin, mouth, nose, and throat irritation.
- Short Turnaround Time: Takes shorter time processing, curing, and drying as compared to wet stoving paints.
- Low Cost: Powder coating is cost-effective in many ways. The powder is less costly than the paint. It also helps you eliminate extra steps.
- Customization: Powder manufacturers can create unique mixtures to match any texture, color, and finish, which are not usually achievable using other coating methods.
Unlike liquid paint, where overspray can cause wastage or loss of the material, uncontaminated power overspray can be reclaimed and reused for future applications.

How Much Does Powder Coating Cost?
The actual cost depends on the size and complexity involved in the project. However, powder coating tends to be more affordable than spray or wet paint and many other coating procedures.
What Colors Does Powder Coating Come in?

In addition to colors, we also offer texture choices – high, semi, and low gloss, clear coating, and metallic coats.
Is Powder Coating Better Than Paint?
Powder coating is better than wet paint in many terms. It delivers better performance as compared to wet paint. It is more resistant to tear and wear because of its thermal bonding that creates thicker layers and excellent surface finishing.
Powder coating offers superior color retention that does not fade off with exposure to sunlight, heat, and moisture.
Compared to spray/wet paint, powder coating is safer because the active material is free of solvents and other toxins. On the other hand, paints usually contain volatile organic compounds, solvents, and toxins that can be harmful if inhaled.
When it comes to mechanical convenience, powder coating provides greater strength and higher flexibility than spray finishes.
Can You Paint Over Powder Coating?
Yes, we can paint over powder coating if required. This needs the right choice of materials and preparation.
If there is any rust, we use sandblasting to tackle the oxidation and prepare the surface for a successful application of paint over powder coating.
How Long Does A Powder Coating Last?
As mentioned above, powder coating is highly resistant to environmental impacts, tears, and wears.
Thus, it enjoys a long-life and retains its finish for longer. It is important to note that powder coating is pre-processed to ensure its longevity.
