How Powder Coating Mooresville NC Contractors Can Help You

By Gwen Lowe


Substrate materials such as metals experience problems like corrosion, rusting, flaking, chipping, and effects of impacts. With time, when metals remain exposed to weather elements like sunlight and moisture, they degrade in quality and their lifespan reduces. In order to protect them and make them last for longer, you can seek the help of powder coating Mooresville NC contractors to apply a coat on metal substrates before you make the finished products.

Its use stretches from things like the bicycles to the furniture. The finish is achieved by using electrostatic charge or compressed air. When the powdered material is applied on the surface of substrate, it is taken through a heating process until it reaches a melting point. As the coat material melts, it flows and spreads evenly over the substrate material thus creating a uniform and even finish, which is resistance to damage.

During the process, the substrate is blasted and the stripped in order to remove any debris and dirt. The presence of debris, dust, and dirt can affect the quality of the finish. When it is cleaned or stripped properly, the coating adheres properly to the substrate. Although an optional process, a pretreatment with use of a chemical is applied in order to protect and clean the substrate surface.

Any experienced coater will apply the pretreatment process in order to ensure that you get the best results in the finished work. The cleaned and stripped surface is then rinsed properly and dried completely before a coat is applied. This coat process results to higher quality products with uniform surfaces free of bubbles and sags.

Products coated using this process have a dry film coat, which is thick than that obtained through spray painting. In powder coats, the thickness is about 4 to 10 times of that of the traditional liquid painting. The wet painting is usually applied in thickness of about 1 mil or one thousandths of an inch. On the other hand, the powders coats are applied of thickness of about 2 to 6 mils particularly of decorative finishes.

Such powdered coats are flexible, and they can withstand bending without flaking or cracking. Where coats crack and flake especially when the substrate material bends, it means they can deteriorate fast and wear out thus exposing the protected material. However, this powdered coat adheres firmly to the surfaces, and it does not crack or flake even when you bend the metals. This means that the coats can last for long and offer good protection.

When cracks occur on coats, they expose the material that is coated to elements like moisture and heat. Tests on powdered coats have demonstrated an elongation of about 100 to 800 percent before failing. One of the major functional roles of coating substrates especially metals is to prevent corrosion.

One of important aspects in industrial processes is having procedures that are environmentally friendly. The powdered coats are environmentally friendly, and do not present significant fire, health, and environmental hazards. The process is termed as nuisance dust because it makes a dusty mess when it spills over the surface. This process does not produce carcinogenic compounds as may be found with other processes like spray paints. Besides, it does not produce volatile organic compounds.
