When Searching For Elegant Powder Coating Mooresville NC Needs The Priority

By Maryanne Goff


When in need of nice powder coating Mooresville NC is the place to consider first. Powder coating is a kind of coating that is applied as free flowing and dry powder. The powders may be thermoset or thermostatic polymers. The coats are applied electrostatically, followed immediately by curing under intense heat in order to trickle freely and form a skin. Most individuals find it hard to distinguish between standard liquid paints and powdered coats.

Differentiating between the two requires some skills and once one is aware of what to look out for then it becomes quite easy. The coat does not need a liquid to maintain the filler parts and binder in suspension form. The coat creates a harder finish, which is tougher as compared to that of a conventional liquid paint.

The coats are majorly applied on metals such as automobile and bicycle parts, household appliances, and aluminuim extrusions among many others. With new technology, some special methods are applied that allow coating of materials like medium density fibreboard shortened as MDF. Coating such materials is difficult because they are non-metallic.

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 disadvantage with this particular technique is that it is difficult to apply thin films. In addition, it is quite costly to apply thin paints on smaller jobs. Thinner films cannot hide metal faults that might have come about during manufacture. In addition, thin coats may reveal fingerprints. The overspray can be recycled if only the color used remains unchanged throughout as this becomes hard if many colors are used.

The application procedure is sub-divided into 3 major stages. The stages are powder application, curing, and part preparation or pre-heating. Pre-heating entails removal of metal oxides, oil, welding scales, grease, and soil from the surface prior to applying a coat. This may be done by different mechanical and chemical techniques. The selected clearance technique depends on factors like the expected results and the size of the material.

The application of the films is done by use of electrostatic guns. Guns impart positive charges on the powders that are then sprayed onto the object by compacted or mechanical air. The electrostatic charges then impart the powders onto the surfaces. The nozzles are of varied shapes and are selected as per the design of the work piece. When the powder is applied the objects are heated in order to melt the paint into an even coat.

There is ongoing research on the technique that will see new application processes, formulations, and advanced equipment being introduced into the market. According to current records, industrial uses such as automotive, furniture, and appliance industries are the leading users of this technique. With improved technology, this technique has been incorporated in other areas such as telecommunication and information technology. Therefore when in need of elegant powder coating Mooresville NC has to be prioritized.
