POWDER COATING GUNS
Corona System: This technique is based on the principle that the cascade inside the gun body sends a high voltage to the needle at the tip of the gun, electrically charging the paint coming out of the gun. The high voltage disrupts the neutral state of the air and creates old ions. These ions cling to each other or to the nearest object, i.e. dust particles. Thus, the powder paint particles are charged and sprayed onto the previously grounded surface.

Tribo System: This system is based on the electrostatic charging of the powder paint particles through special paths in the gun due to the effect of friction. The difference of the Tribo loading system from Corona is that there is no high voltage cascade in the gun and the powder particles are charged by friction. This mechanism is activated by the contact between two substances of different charges. The specially designed loading paths in Tribo guns are made of Teflon, which prevents the accumulation of powder paint due to its mechanical properties and allows a fast loading without sticking to the surface.
