Difference between powder and Paint
What Is Powder Coating?
Powder coating is a highly durable colour application designed for metal surfaces. It forms a strong, protective layer over the object and is typically made from polyester, epoxy, nylon, or polyurethane resins, sometimes blended with metallic additives. The coating starts as a fine, dry powder that is sprayed onto an electrostatically charged metal surface to ensure strong adhesion. The coated part is then cured in an oven or furnace, where the powder melts, flows, and hardens into a smooth, uniform finish.
Like liquid paint, powder coating comes in a wide range of colours, textures, and finishes. However, it is generally considered more efficient and environmentally friendly because excess powder can often be reused, disposal is simpler, and it releases significantly fewer Volatile Organic Compounds (VOCs) into the air. In addition, powder coating typically outperforms liquid paint in both longevity and durability.
Because powder coating requires oven curing at high temperatures, items made of multiple components must be fully disassembled beforehand. Any parts that could melt—such as plastic—must be removed prior to coating. Once applied and cured, the coating is extremely tough, meaning assembled components may no longer come apart without damaging or completely stripping the finish.
Choosing Between Liquid Paint and Powder Coating
At Instant Coatings, we regularly work on automotive components such as wheels and calipers. Many customers come to us after previously trying liquid spray paint on their rims. Since wheels are constantly exposed to weather, road debris, and daily wear, hardware-store spray paints often begin to chip or peel within a short time. The same issue frequently occurs with brake calipers.
Because both finishes can look similar when freshly applied, it’s easy for consumers to assume they’re getting a long-lasting coating—even when they’re not. Some businesses may charge premium prices for liquid-painted parts that don’t offer the durability customers expect. While there’s nothing inherently wrong with spray-painting calipers, it’s important to understand that some coatings may only last a short time despite the higher cost.
When deciding which coating system is right for your project, it’s best to consult a local paint or powder coating professional to explore your options. Our shop stocks approximately 150 colours, displayed in our showroom. When you visit us in Woodbridge, our team can help you choose the exact colour and finish you’re looking for, or inspire you with the wide variety of possibilities available in powder coating.
