APPARATUS AND METHOD FOR TREATING SUBSTRATES TO RESIST GREASE AND OIL PENETRATION AND TREATED ARTICLES THEREFROM

摘要

An apparatus and method for treating a substrate to provide grease and oil resistance the substrate. The apparatus and method includes, applying a first film layer of a non-fluoro grease and oil resistant chemical on the surface of the substrate to form a first film layer on the surface of the substrate. The apparatus also includes applying a second film layer of a water resistant chemical over the first film layer to prevent the first layer from being contacted by water and to hold the first layer to the surface of the substrate.
