Electrostatic Spraying

The UK electrostatic spraying market is developing but is still untapped compared with other painting related markets. At CeilCote we believe electrostatic spraying provides a quality finished surface when applied correctly. Skilled applicators follow tried and tested procedures from detailed preparation to spray application. The electrostatic spraying industry has evolved over the last 20 years.

The electrostatic spraying application uses a charge applied to the paint to assist in the paint adhering to the sprayed surface. Electrostatic spraying can be used to restore areas such as metal window frames, furniture, balustrades etc. Building facilities managers often specify this method of spray application when carrying out refurbishment works. With little to no overspray this method of spray application is well suited for small tight areas. Electrostatic spraying brings powerful capabilities of efficiency and cost reduction to any industry that applies liquid solutions. Tests have shown that our sprayers give 4-10 times better coverage than conventional sprayers!

Electrostatic spraying has been used for many years in the automotive industry to apply paint. The latest technology uses lower voltages, making it safe for exciting new applications. Air-assisted electrostatic sprayers produce electrically charged spray droplets which are carried to the target in an air stream. Electrical charges on the surface of the spray particles cause them to be attracted to the target where they are directed.

Coulomb's Law says that opposites attract, or more specifically, unlike electrical charges attract each other. Because of Coulombic forces when charged spray particles are near any object they will be attracted to that object. They will follow electric field lines and wrap around and coat all sides.

The advantage of this physical principle is to allow spray applicators to do a better job and to help provide less environmental impact. In addition air-assistance helps with spray delivery. Air is necessary in electrostatic spraying to cause the charged spray to push deep into complex targets. Electrostatics, with air-assist, plus the right droplet size is a good combination for the best spray job.
