Powder coating for furniture.

Powder coating



Powder coating is a modern finishing material that is popular and much used at this time. The powder coating can layer metal surface a very high efficiency. Its application can provide a very thin layer but very strong coating. However the paint application requires a special machine that is quite expensive. A high-temperature oven, electrostatic spray equipment and fluidized equipment are needed to apply the powder coating material. The paint also can only be used to coat goods made of metal. The use of electrostatic spray equipment is more efficient for the metal. With the recycling process, the powder coating has very high efficiency material application.
A coating in the powder form is put into a hopper for fluidized and poured into a spray gun or other spray equipment. In the spray gun, the material is electrically charged and then sprayed into the work pieces that need to be coated. While the work pieces are connected to the ground and then the electrostatic power will attract the finishing material to attach to and cover the entire surface of the work pieces. The powder that is not attached to the work piece can be collected again to be reused. It means almost there no waste material is produced.
After the work pieces have been coated with the paints they are brought into an oven to be heated. In this oven the layer of powder paint is heated, melted to coat the surface beneath and forming a thin, smooth and uniform layer of coating. The temperature in the oven is very high about 160C - 200 C. For enamel paints the temperature is even higher up to 700 C
Powder coating has a very high material efficiency transfer and very strong coating layer. The paint material used is a kind of baking paint that must be heated to get dry and cured, but soon it dry it would stick to the surface and coat the surface with a very strong bonding. Powder coating is very effective to coat a metal material when the electrostatic force can work maximally to make a high efficiency of material usage.
 
Powder coating for furniture.

 
Now there are many furniture industries that use powder coating to coat their furniture products. Powder coating is widely used in metal furniture industry. The furniture made from metal with simple models are very suitable with the powder coating system. Furniture made of metal that has been cleaned and treated well is then sent directly to the booth for powder coating application. The paint application is mostly done when the furniture is still in the parts instead or big complete furniture products.
There are several types of powder coating such as: enamels powder, polyurethane, polyester, epoxy and epoxy polyester. Each type of powder has each advantages and disadvantages, while the most widely powder coating used for furniture is the polyester type. This material can produce a thin layer of finish, strong and quite stable against chalking that could also be used for outdoor.
Powder coating is much use on metal furniture that requires strong film layers with simple models. Goods such as: deposit box, refrigerator, or cabinets, and even tables or chairs from the metal are be able to be finished using powder coating. Powder coating is also suitable to be used for outdoor furniture. The metals parts in combination with wood, rattan or other natural product in the outdoor furniture such as; legs, frames, or other accent can be coated with powder coating.
This powder coating although can produce a very strong film and protection but the resulting color and appearance is very limited. This material can not produce a finish with special effects such a finish with a stain and glaze application in a lacquer finish. The resulting appearance is the solid color in many colors. There are many colors is available but of course the color choice is rather limited. The automotive coating which are also used for the metal for outdoor furniture has a lot more color  variation and choice.
The powder coating is more used to the products that require the higher protection instead of the beauty appearance. To generate furniture with more beautiful appearance some finisher are doing the finishing process on the powder coating layer. The finishing process with stain and glaze with many effects can be applied to produce more attractive and nice finishing looked.
