Electrostatic Spray Coating

Electrostatic spray coating is used in a wide variety of applications to create a barrier or to retard the movement of electrically charged particles. The coating is created with the aid of an electrostatic charge that acts upon the charged particles. The particles are then slowed down or deflected. The deflected particles will not be able to reach their ends and will be forced to go around the surface they are attached too. In this way the coating will provide protection from electrostatic discharges and electrical damage.

Due to the water-conductive characteristics of the paint, water based paints are also too electrostatic. Therefore, they require specially designed electrostatic spray systems. In particular, certain conductivity additives can be used to add some electrostatic properties to them.

For electrostatic spray application on steel, zinc, copper or bronze, the use of a non-permeable oil-based coating is usually required. A protective spray can further be used to avoid corrosion of the metal while it is being sprayed. Another common material used for these applications is silicon carbide, which has good electrical and physical resistivity. Silicon carbide can also be coated with paint in order to make it more resistant to erosion and rusting. This coating is often called a thin metal.

The other common types of electrostatic spray application are known as solventborne and electrostatic spray coatings. Solventborne coatings are applied over a liquid substance. The liquids are usually water or some kind of oil. The substances used in solventborne coatings must have a very low solvents count in order to make sure that the coating does not attract any moisture or seep through into the space between the coating and the liquid to decrease its conductivity.

Electrostatic paint has been used extensively in industries. It is particularly suited to some kinds of machinery because it prevents the wheels from getting stuck when they are moving at high speeds. It is also used in brake pads and other parts of the motorcycle. By making use of this kind of paint, you can increase the friction between the wheels and reduce the wear and tear of the tires. Thus, your motor will run longer before you need to replace it. Electrostatic spray painting also helps to improve the overall performance of a braking system.

Electrostatic spray coating also ensures that your electrical components are not damaged by static electricity. This is because the higher the conductivity of the materials that you are coating, the less likely they are to be damaged by this kind of energy. Therefore, the use of electrostatic charge insulators increases safety in electrical installations and apparatus. Some of these conductivity agents are non-permeable and have a relatively higher level of resistivity, which means they can withstand static electricity for a longer period of time before they become damaged.

These coatings are available as liquid, dry powder or in a spray-able form. Most of the people prefer the dry powder versions because of their ease of application. The spray-able versions are easier to apply by using a spray gun, but they are more expensive. Both forms work effectively, but the cold method is believed to be more effective. The Quaternary ammonium salt form of these coatings is the most commonly used as a resistivity initiator, especially in the case of applications that require a chemical-resistant coating.

Some of the other materials that can be used as conductivity initiators include polyurethane, polystyrene, polycarbonate, calcium carbonate and the like. There are other methods, too, which include combining the liquid and the powder, or by applying an electrostatic charge on the surface to initiate the coating. The electrostatic spray coating is made up of oxides that have specific intensities, based on the characteristics of each material. Electrostatic discharge has been a known initiator for years, but this process is usually not performed by manufacturers. Because of this, electrostatic coatings are usually carried out only by manufacturers who have had experience in the field.
