Curtain Coating

Definition - What does Curtain Coating mean?

A curtain coating is a process in which the object or substrate that needs to be coated is guided through a curtain of fluid. This curtain of fluid is located in a gap between two conveyors. A tank containing the coating fluid supplies the equipment in which a thin screen of coating falls down in between the two conveyors.

Corrosionpedia explains Curtain Coating

The thickness of the coating layer is mainly determined by the conveyor speed and the amount of fluid leaving the tank (i.e., pump speed). Curtain coating is a pre-metered method.

Curtain coating is a technique used in the converting industry to modify the properties of a substrate.
