Precise Painting that is Environmentally-Friendly
The term “Electrostatic Painting” describes a process by which the properties of electricity are used to apply a high-solids coating to any conductive material. Using the “opposites attract” principle, the painting equipment is charged with one electrical polarity, while the metal objects to be painted are charged with the reverse polarity. When the coating is sprayed it is attracted to the metal surface and electronically bonds with that substrate. What results are well-coated surfaces and virtually no overspray.
Electrostatic painting has been used in the controlled environments of factories for many years. It has only been in the last decade that mobile equipment was developed that allowed coatings to be electrostatically applied in nearly any situation in any location.
The cost of electrostatic painting
Electrostatic painting is not the cheapest method of applying a coating to metal surfaces, but it may actually be the most cost effective, since there is very little preparation required to protect the area where the painting is to occur and there is little or no overspray to clean up afterwards. Painting electrostatically causes a minimum of disruption in the workplace, whether it is a factory, where machinery is to be returned to its former glory, or an office where file cabinets and other metal objects are to be rendered beautiful again. The coatings may be applied during a normal shutdown for the evening or over a weekend. The workers return to a bright, clean workplace without having been disturbed or interrupted in their duties.
The need for professional application
Electrostatic painting isn’t for amateurs. It requires highly specialized spray equipment and the knowledge of how to use it, an understanding of which types of coatings to select and how to prepare them for application and how to prepare the substrate to be coated and the area in which the task is to be accomplished. This is definitely not for the do-it-yourself-weekend-painter; rather it is for the properly trained and equipped professional.
Materials that can receive electrostatic painting
Only metal surfaces; steel, aluminum, copper or other conductive material, are candidates for electrostatic painting. It is used in factory set-ups where fabricated, extruded or rolled metal parts are finished before assembly into completed products. It is used on bridges, standpipes, radio towers and other outdoor metal structures. It is used in offices to repaint file cabinets and other metal office equipment. It is used to refurbish production equipment, rolling stock, farm equipment, trucks and trailers and any other metal objects, mobile or immobile.
The end result of electrostatic painting is a clean, smooth, fully-coated substrate that has a hard, durable surface. By their very nature, high-solids, electrostatically applied coatings are very tough and very well bonded to the surfaces coated. They are long-lasting and attractive. Most importantly, they have been applied with very little fuss, bother or disruption to the workplace.
