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.
Powdered coats do not require a liquid in order to keep the binder and filler in liquid state. In addition, this type of coating is applied electro-statically. The application is followed by curing to form a good coat with a harder finish in comparison to that of conventional liquid paint. This technique is used in coating of metals although with improved new technologies medium density fibreboards may be coated using the technique.
There are two main forms of powdered coatings. The 2 include thermosets and thermoplastics. Thermoset powders melt and flow out prior to chemically reacting to give high molecular polymers upon exposure to high temperatures. The whole process is what is known as curing and it usually results in a mesh like structure. The process occurs at a predetermined temperature and is done for a specific duration, which depends on the polymer in question.
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.
A surface to be painted has to be thoroughly prepared. The preparation includes removal of all former metal oxides, welding scales, oils, lubrication greases, and soil. Mechanical and chemical cleaning methods may be applied where necessary. There should be systematic cleaning of the surfaces because this enhances bonding of the coat to the metal.
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 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.
