Powder Coating Research

Powder coating is the process you use to apply a coating without using solvents. This is the newest coating technique in the industry right now. You usually apply this type of coating to create a hard finish on metals and because it allows you flexibility to apply on a different layers of thickness. You would see this finishing in materials such as aluminum, medium density fiberboards, fusion-bonded epoxy and acrylics, usually on automobile finishing.

To produce the powdered finishing, polymer granules are mixed with pigments and powder ingredients. The mixture is heated in an extruder. It is then cooled and rolled flat before being broken into pieces. The chips are then milled to be produced as powder. Given that you can mix any type of pigment into the mixture, the colors you can produce are limitless. …show more content…
This may sound like a very tedious process, but what you can do is actually use an electronic gun to spray the powder. The gun gives an electronic charge to the powder causing it stick to the surface. The object is usually heated causing the powder to melt and sticking to the surface producing the hard coating. This is similar to the process of applying to dry paints. The final cured coating is similar to the effects of applying a two-pack wet paint. By giving the object a powder coating, the product ends up relatively hard and abrasion resistant.

There is a possibility for failure. Problems might occur when applying the powder coating. This is due to a lack of preparation. Each product needs different preparation depending on the material of the object. Search online for tips on avoiding these
