Curtain coating process creates an uninterrupted curtain of fluid that falls onto a substrate. The object to be coated, such as a door, is passed along the conveyor at a controlled speed and so receives even coating on its upper face. The curtain is created by using a slit at the base of the holding tank, allowing the liquid to fall upon the substrate.
