Powder coating is a means of painting that has experienced seismic popularity. Powder coating can be used by consumers and industries to apply both decorative and protective finishes on any metal. A mixture of resin and pigment is ground finely to produce the powder used for painting. The powder is sprayed electrostatically on a surface for coating. Charged particles of the powder adhere to surface that is electrically grounded to produce durable, tiptop, uniform, and professional finish. Powder coating is aesthetically appealing.
How it works
It is important to understand how powder coating works to appreciate the benefits of this marvelous technology. Powder coating, unlike wet pain operates in a dry environment. It involves electrostatic spray deposition process which is not friendly to water. Positive charged dry powder is sprayed on negatively charged unfinished fabricated metal object. The electrochemical charge attaches powder to the metal. Negative and positive current electric polarization creates an even coating. Bases used in powder coating include polyester, acrylic, and polyurethane.
Profesional powder coating is used in the automotive industry to paint bumpers, door handles, wheels, and door handles. It is also used in architecture to coat doors, windows, and furniture. Lastly, it also benefits the appliance industry to coating washer tops, water heaters, dishwashers, air conditioner, and refrigerators.
So why get powder coating?
One of the main reasons why industries, business, and consumers endear powder coating is because it is long-lasting. It is more durable by far than other options. These durable color finishes are economical and can be applied in any metal. Compared to other surfaces, powder-coated surfaces are more resistant to wear, fading, chipping, and scratching. This means that you will benefit from vibrant and bright colors for longer. During the cutting process, the powder forms strong chemical bonds that enhance durability. As metal move and vibrate there is only small amount of flexing.
Powder Coating has a Shorter Processing Time
The processing time for powder processing is also relatively shorter since it does not require flash off or solvent. The powder-coated articles pass into the oven, directly saving time, and space.
Powder Coating is Eco-Friendly
Powder coating is friendlier to the environment. Liquid paints have Volatile Organic compounds (VOC’s) containing solvents. On the other hand, powder coating has a negligible amount of VOC and no solvents. Designer and consumers should embrace powder coating bay area in the bid to protect the environment from pollution.
Reduce the Risk of Health Hazards to Workers
As mentioned above, powder contains no solvent. It significantly reduces irritation in the throat, nose, and mouth. Contrastingly, liquid paint requires washing and emulsification with hot water and soap once it comes into contact with skin of the operator. Generally, powder does not irritate the operator skin. If you come into contact with the powder, you can easily remove warm water.
Professional powder coating uses electromagnetic charge which reduces spillages significantly. In fact, there is very little spillage. But that is not all. You do not have to wait for one coat to dry before spraying the next. Application is done in a single step. The coating cures evenly. This does not only save time but also operating cost.
Powder is Cleaner
The powder is cleaner to apply than wet paint. Also, it is very easy to clean a spray both using rubber squeegee while normal air extraction is operational in the booth. Avoid using air hose or brushes for the cleaning process. You should use vacuum cleaner to remove powders pillages outside the booth. The vacuum should be fitted with dust-tight or air-driven motor.
In addition to cost saved by simplifying the application process, the powder is less expensive compared to wet paint. Also, powder coating allows you to purchase raw materials that are specific to specifications and size of the job at hand. The powder also takes less storage space than paints cans.
Powder coating is easy to maintain
Best Powder coating is easy to maintain in the long run. You do need special solvent or cleaners to keep it clean. Regular soapy water will do the trick. Better still, it is corrosion resistant. Moreover, rust should be the least of your worries.
