Electrostatic Spray Tribo Charging is the second most common method of spraying a powder coating. This method relies on the powder to develop a charge while passing through special hoses and guns. As powder contacts these non-conductive surfaces,electrons are stripped off of the particles due to friction. These particles then develop a powerful positive charge. No high voltage or lines of force are used which allows for easier penetration into deep recesses. Tribo charging is efficient in developing a staticRead More …

Electrostatic Spray (Corona charging) is the most common method used in powder coating .The process disperses finely ground powder into corona field at the gun tip applying a strong negative charge to each particle. These particles have a strong attraction to the grounded part and deposit there. This process can apply coatings between 20um-245um in thickness. Corona charging can be used for decorative as well as functional coatings. Virtually all resins with the exception of nylon can be applied easilyRead More …
