Powder coating for furniture.

Powder coating is a modern finishing material that is popular and much used at this time. The powder coating can layer the metal surface with 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 fluidization 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 workpieces are connected to the ground, the electrostatic power will attract the finishing material to attach to and cover the entire surface of the workpieces. 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 workpieces 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 160°C - 200°C. For enamel paints the temperature is even higher, up to 700°C.

Powder coating has a very high material efficiency transfer and a 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 when he dries, he will 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 the metal furniture industry. The furniture made from metal with simple models is 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 of big complete furniture products.

There are several types of powder coating, such as enamel powder, polyurethane, polyester, epoxy, and epoxy polyester. Each type of powder has its own advantages and disadvantages, while the most widely used powder coating for furniture is the polyester type. This material can produce a thin layer of finish that is strong and quite stable against chalking and could also be used outdoors.

Powder coating is much used on metal furniture that requires strong film layers with simple models. Goods such as deposit boxes, refrigerators, or cabinets, and even tables or chairs from the metal, are able to be finished using powder coating. Powder coating is also suitable to be used for outdoor furniture. The metal parts in combination with wood, rattan, or other natural products in the outdoor furniture, such as legs, frames, or other accents, can be coated with powder coating.

This powder coating can produce a very strong film and protection, but the resulting color and appearance are very limited. This material cannot produce a finish with special effects, such as 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 available, but of course the color choice is rather limited. The automotive coatings, which are also used for the metal for outdoor furniture, have a lot more color variation and choice. The powder coating is more used on the products that require the higher protection instead of the beauty appearance. To generate furniture with a more beautiful appearance, some finishers 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 a more attractive and nice finishing look.
