Abstract:
1. A method for preventing and/or eliminating face-plugging on an inlet of an aftertreatment device comprising: forming a substrate having an end and an interior with a cellular structure that is configured to enable fluid flow through the substrate; disposing an end surface on the end of the substrate and on outer surfaces of the cellular structure located at the end of the substrate, the end surface including an amount of a chemical coating that is configured to prevent and/or eliminate face-plugging on the substrate and cellular structure; and wherein the disposing the surface on the substrate further comprises at least one of: applying the amount of the chemical coating on the outer surface at the end of the substrate and on outer surfaces of the cellular structure present at the end of the substrate without the amount of chemical coating extending into the interior of the substrate; and applying the chemical coating on a three-dimensional topographical configuration on the end of the substrate without the amount of the chemical coating extending into the interior of the substrate, such that the chemical coating faces outward from the end of the substrate.
