Unlike liquid paint, powder coating is an application in powder form applied electrostatically and cured under heat to form the coating. It is used to coat metals, among other applications. Powder coating is one of the most common types of applying paint. It is durable, eco-friendly, cost-effective and produces very little waste. The coating is done in a sealed booth so there is no risk of air pollution. It is tougher and harder than conventional paint. But does that mean it lasts longer? That is subjective to what it is applied on, and the type of powder treatment.
Powder coating is used in various metal parts, such as the exhaust, kitchen appliances, or brass railings. It is durable as compared to other alternatives. There are several kinds of powder treatments.
- Polyester Powder Coating: For extra durability, polyester is used for its UV resistance and tough chemical composition.
- Epoxy Powder Coating: Epoxy, which is used as a primer, is also extremely durable.
- Urethane Powder Coating: Although urethane has better matting ability, it tends to be more expensive.
On average, the life span of the treatment depends on the type of powder coating used. Powder coating professionals can guide you best on the most durable application for your requirements. If high-quality powder coating is applied by experienced professionals in the field, the coating can last up to 20 years with excellent resistance to extreme weather conditions. It does not corrode easily and looks gleaming for many years, so your investment goes far.
Powder coating limits corrosion, protecting the metal. Since it is applied electrostatically, the surface to be applied on needs to be thoroughly clean for which pre-treatment is important. Pre-treatment is a method where the existing coating and corrosion is stripped away so that the powder coating can be directly applied on the bare metal through a multi-step substrate process for smooth application. If it is not applied this way, the surface is prone to chipping.
Powder coating tends to be more expensive than liquid painting but it is more durable and withstands harsh weather conditions better than liquid paint. This is why it can be applied to a wide range of residential appliances from dishwashers to fireplaces and air conditioners, and diverse industrial-use machines. That does not mean it’s the most durable alternative, however.
