ABSTRACT:
A system for spray coating a substrate such as a flexible web of plastic film with a gas barrier coating containing a polymer dispersion. The system includes a spray coating booth or chamber including spray nozzles dispensing a spray of coating material onto the surface of a web of material continuously moving into and out of the coating chamber. A series of feed rollers move the web into the coating booth into proximity to the spray nozzles such that on actuation of the nozzles a stream of coating material coats both sides of the surface of the web with a wet coating layer. The coating booth includes a system for containing and removing the airborne liquid overspray carried from the booth with the web without disturbing the wet coating on the web and without substantially drawing of overspray from the coating chamber.
