CA 2322782

A coating composition for the linerboard of corrugated paperboard provides water and grease resistance but is water vapor permeable, and thus permits a different mode of manufacture of corrugated paperboard when aqueous adhesives are employed in the assembly of the linerboards and corrugated medium; in particular the linerboards may be coated with the coating composition prior to assembly of the corrugated paperboard because the water vapor permeable coating permits escape of the water of the aqueous adhesive, during drying of the assembled components of the corrugated paperboard; the coating composition employs a styrene-acrylate copolymer and a C14-C18 fatty acid complex of a metal ion having an oxidation state of at least 3, such as chromium.

L'invention concerne une composition de revêtement pour la couverture du carton ondulé qui assure une imperméabilité à l'eau et aux graisses, mais qui est perméable à la vapeur d'eau et qui permet de ce fait de fabriquer de manière différente du carton ondulé lorsque l'on utilise des adhésifs aqueux dans l'ensemble de la couverture et du support ondulé. Plus précisément, la couverture peut être enduite de la composition de revêtement avant l'assemblage du carton ondulé parce que le revêtement perméable à la vapeur d'eau permet l'évacuation de l'eau de l'adhésif aqueux pendant le séchage des composants assemblés du carton ondulé. La composition de revêtement utilise un copolymère styrène-acrylate et un complexe d'acides gras C14-C18 d'un ion métallique présentant un état d'oxydation d'au moins 3, comme le chrome.
