    When in search for powder coating Mooresville NC is the place to go. As the name implies, powdered painting is a method of forming coatings using free flowing and dry powders. This technique has existed for a long time. It is distinct from its liquid coating counterpart in many ways. The distinctions are in form of mode of application, formula, and appearance.

    Powder coatings do not necessarily require a liquid to sustain the binder and filler parts in liquid state/form. In addition, these types of coatings are applied electrostatically. The application is immediately followed by curing to form a nice coat with a harder surface in comparison to that of liquid paint. The method is applied in coating of metals even though with better new technologies in use medium density fiberboards may be coated by this technique.

    There are two major types of powdered coatings. The two are thermoplastics and thermosets. Thermoset powder melts, flows out before it chemically reacts forming a high molecular weight polymer when exposed to high temperature. This process is what is referred to as curing and it results in a net like structure. This process occurs at a given temperature and is carried out for certain duration, which is dependent on the type of polymer.

    Most polymer powders cure at an approximated temperature of 200 Fahrenheit in 10 minutes. The producer of the powder specifies both the heating duration and the necessary temperatures. The heating is sometimes done using infrared ovens or convection cure ovens. A laser cure is used if one wishes to cut on the time taken during heating.

    Surfaces to be coated have to be carefully prepared. The preparation should include removal of all former welding scales, metal oxides, lubrication greases, oils, and soil. Mechanical and/or chemical techniques of removing the mentioned imperfections may be applied where applicable. There must be efficient cleaning of the surfaces since this improves adhesion of the coating to the metal.

    Since not every coat is permanent there has to be away of removing old and worn out coatings. Most people resort to thinners without knowing that they are ineffective on powdered coats. The most effective way is to use acetone or methylene chloride solution. Benzyl alcohol can also be used in place of the mentioned chemicals. The other two efficient methods are using sulfuric acid of a concentration of up to 98 percent or abrasive blasting.

    This technique has its own disadvantages. The disadvantages include inability to apply smooth thin coats. Faded coats are produced when the thickness of the film is reduced. Several techniques have to be combined in order to come up with thin coats. As a result of this the cost of applying thin coats is higher compared that of applying thick coats.

    When in search for powder coating mooresville NC should be accorded priority consideration. Professionals within this region strive to come up with the best flawless coatings. They use every method possible to ensure customers are getting better services at affordable prices. Details on them is accessible on their consumer blogs over internet for questions.
