When one needs professional powder coating Mooresville NC presents the best choice to go for. Powder coating is a form of coating, which is applied as dry and free flowing powder. The substance can be either thermoset or thermostatic polymer. The coat is applied electrostatically, followed by curing under heat to enable it to flow freely and form a skin. Most people find it difficult to differentiate between a powdered coat and a conventional liquid paint.
Drawing a distinction between the methods requires skills and once a person knows what to look out for then this becomes simple. Powdered coats do not require liquids to keep the binder and filler parts in liquid state. Powdered coats form harder finish, which is in turn tougher compared to that of standard liquid paints.
The coats are mainly applied on metallic objects such as aluminuim extrusions, automobile and bicycle parts, and household appliances among several others. With modern technologies, some special techniques are applied, which allow coating of MDF materials. MDF stands for medium density fibreboard. Covering such materials using this method is tricky because they are non-metal.
Several advantages come with this method including being non emitter of VOC. VOC is the short form for volatile organic compounds. It can produce thicker coats without sagging or running and the coatings are recycled. The cost for capital equipment, running and operating the production line is less compared to that of other coating processes. There are fewer errors in this method because it is not easy to differentiate between horizontally and vertically coated surfaces. It is also easier to obtain a wide variety of specialty effects.
The drawback with this technique is that it is not simple to apply a thin film. In addition, it becomes quite costly to apply such layer on smaller jobs. Thin films cannot hide metal defects that may have come about at the time of production. They can also reveal fingerprints. The overspray may only be recycled if only the same color is used throughout because it becomes difficult if several colors are used.
The application formula is divided into three major stages. The steps are part preparation or pre-heating, powder application, and curing. Pre-heating involves removal of welding scales, oil, metal oxides, soil, and grease from the work piece prior to application of a coat. This may be achieved using several and different mechanical or chemical techniques. The chosen technique is determined by factors such as the size of the work piece and the wanted results.
Film application is done using electrostatic guns. The guns impart positive charges to the powder that is then sprayed on the object by compressed or mechanical air. Electrostatic charges then accelerate the powdered substance onto the surface. The nozzles are shaped differently and are chosen according to the shape of material to be worked on. Once the paint is applied the object is heated so that the powder melts into an even coat.
There are underway researches on the method that will result into new application procedures, formulations, and improved equipment introduced in the market. As per the present records, commercial uses like furniture, automotive, and appliance industries are the chief users of this technique. With advanced technologies, the method has been introduced in other fields like IT and telecommunication. This is why when in need of powder coating Mooresville NC should be prioritized.
