Electrostatic Detearing

Definition - What does Electrostatic Detearing mean?

Electrostatic detearing is a process for removing excess wet coating material, such as drips, from the bottom edge of a dipped or coated object by passing it through an electrostatic field. Electrostatic detearing removes the tear-shaped drops that form on dipped objects.

Corrosionpedia explains Electrostatic Detearing

Whenever there is excess wet coating after dipping an object, there is a chance the excess will not remain attached to the surface and will drop. In order to remove the excess coating properly and effectively an electrostatic detearing process is performed. The process consists of passing the dipped object, after a limited period of draining, over a grid at a high-electrical potential. The blobs and thick edges of paint are removed from the article by their attraction to the grid.
