When in need of powder coating Mooresville NC should be given priority consideration. As the name suggests powdered painting is a technique of forming coats using dry and free flowing powder. This method has been in existence for long. It is different from its liquid paint counterpart in several ways. The differences are in form of formula, appearance, and mode of application.
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 2 main types of powdered coats. The two include thermoplastics and thermosets. Thermoset coats melt out and flow before undergoing chemical reaction to form higher molecular polymers when exposed to great temperatures. This entire process is what is called curing and usually results in net like structures. Curing occurs at a fixed temperature and is usually done for a predetermined duration that depends on the type of polymer in use.
Typical powder cures at an average temperature of 200 degrees Celsius within ten minutes. The temperature and duration are normally specified by the manufacturer of the powder. The heating can be done by infrared cure ovens or convection ovens. To cut on time consumed during the heating process laser curing is done.
Surfaces to be coated should be properly prepared. The preparation must entail removal of all lubrication greases, soil, metal oxides, oils, and welding scales. Chemical and mechanical techniques of removing this debris may be used where applicable. There should be effective cleaning of the surface as this improves adhesion of the powder to the metals.
Given that not every coat lasts forever there must be away of eliminating worn out and old coats. Most individuals resort to using thinners without knowing how inefficient they are on powdered coatings. The most efficient method is to use methylene chloride solution or acetone solution. Benzyl alcohol may be used instead of the named chemicals. The other two effective methods are abrasive blasting or using concentrated sulfuric acid.
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 need for better powder coating Mooresville NC provides a perfect place to be. Professionals in this region endeavor to formulate the best faultless coatings. They apply every possible method to make sure the client gets better services at reasonable prices. Details about them is available on their blogs on the internet for inquiries.
