Electrostatic powder coating with Mitsuba Tribo Powder Spray Gun

Electrostatic Powder Charging Due to Friction

Tribo Powder Spray Gun

The Tribo powder coating gun, is the purest form of electro static powder charging. It charges the powder using friction, eliminating the issues caused by the Faraday’s cage effect occurs while spraying with Corona guns. Hence used to coat the most complex shapes perfectly.

Frequently Asked Questions

How does powder get charged in Tribo gun?

Tribo charging Guns charge the powder by friction. Powder moving through the gun rubs against the media in the gun and it will get charged.

Which is the better option: corona or tribo?

Corona guns are most versatile guns as they can charge any powder. Tribo guns can only charge powder specifically manufactured for tribo guns. Besides that tribo guns are very sensitive and charging also depends on other factors like atmospheric moisture, powder particle size. As the quantity of powder that can be charged from tribo guns is less, more tribo guns are required to coat.

What is Faraday’s Cage and how does the Tribo gun eliminates it?

Tribo Charges the powder by pure friction within the gun. There will be no free ions in the field to create the Faradays Cage effect. In the product with high amount of Faradays Cage area Tribo Gun coats the deep recess area very easily.

Can I operate both guns i.e., Corona as well as tribo on this panel?

Why do you need a dedicated tribo system when you can operate Corona as well as Tribo guns on the Multistatic panel?

When customer is sure of using only tribo gun for his present and future requirements he can buy this system.

Which powders are suitable for tribo charging?
