Electrostatic powder paint

How Does It Work?

The paint in electrostatic painting has a positive charge and is typically sprayed through a nozzle. Like a magnet, positive and negative charges attract the paint to a metal surface. The paint will then wrap itself around the object that is being painted – typically a grounded, metal object. There is a very high attraction between the conflicting charges of the paint droplets and the object that is to be painted, with the paint being attracted statically to the metal from all directions.

after electrostatic spraying the finished sprayed workparts will be placed into the oven, and the powder coatings generate chemically reaction under the a specific temperature , crosslinking and curing into a polymer coating film, which has a certain physical and chemical properties.

The Benefits Of Electrostatic Spray Painting

The method of electrostatic painting provides numerous benefits, making it a favored choice for various industries.

The "wrap-around" effect

Paint particles with a positive charge 'seek out' uncoated surfaces with a negative charge. This means that the backs and sides of a workpiece draw paint toward them once the front side is coated.

Uniformity

 Electrostatic painting guarantees an even and smooth finish, regardless of the shape and size of the object, making it ideal for complex and intricate structures.

Durability 

 the ionic bonds between the paint and the metal surface underneath it create a long-lasting surface that will stand up to use and the elements.

Resistance

Resists the buildup of dirt and contaminants
