Tribo guns have two weak points. First, it coats at half the speed of a corona- charge powder gun. Second, it works best with epoxy powders. A tribo powder gun should have very long gun barrel. The longer length increases the inside surface area of the thereby increasing the tribo charging. Be careful to spray the powder consistently. The tribo charging effect decreases if powder is sprayed too quickly, because not all of the powder will rub on the interior barrel surface
