How to Prevent Back Ionization in Powder Coating: Causes, Warning Signs, and Practical Solutions
In electrostatic powder coating, achieving a smooth and uniform finish depends on more than just powder quality. Even when the powder formulation is correct and the application equipment is functioning normally, certain electrostatic conditions can still lead to unexpected surface defects. One of these problems is back ionization. Back ionization is particularly frustrating because it can occur during an otherwise normal spraying process. Operators may notice small craters, pinhole-like marks, uneven film appearance, or rough surface areas after curing. InRead More …
