Abstract: The present disclosure provides binder compositions formed with a plurality of binder materials having differing mean particles, the binder compositions being useful to improve washcoat adhesion on a substrate. Adhesion can be improved related to an increase in the binder concentration without a significant or substantial increase in associated viscosity. Such binder compositions can comprise a first binder material formed of a plurality of particles having a first mean particle size and a second binder material formed of a plurality of particles having a second mean particle size, wherein a ratio of the first mean particle size to the second mean particle size about 2 or greater. The present disclosure further provides catalyst compositions, catalyst articles, and emission systems incorporating the binder compositions.

Abstract: The presently claimed invention provides an emission control catalyst article comprising a substrate having an inlet axial end and an outlet axial end, a bottom washcoat layer coated on the 60 to 100% length of the substrate from the inlet axial end to the outlet axial end, and a top washcoat layer coated on the 60 to 100% length of the substrate from the inlet or the outlet or both end of the substrate such that the top coat covers at least 60% of the length of the bottom washcoat layer, wherein at least part of the top washcoat layer and/or the bottom washcoat layer comprises a first portion and a second portion, wherein the first portion begins at the inlet axial end or the outlet axial end of the substrate and exhibits a platinum group metal concentration of 2 to 100 times higher than the concentration of a platinum group metal in the second portion, wherein the first portion comprises 5-50% of the substrate volume and exhibits a three-dimensional axial and/or radial zone arrangement starting from the inlet axial end of the substrate or the outlet axial end or both, wherein the platinum group metal loading in the first portion is 10 to 1000 g/ft, as determined axially from a first end of the first portion to a second end of the first portion. The platinum group metal of the first portion is deposited by spraying a platin group metal precursor solution using an apparatus comprising a spray nozzle connected to the dosing unit via a second supply tube, a control arm device connected to the spray nozzle, wherein said control arm device is adapted to allow the 3-D positioning of the nozzle relative to a substrate face and adapt the radial and/or axial deposition of the platinum group metal within the individual channels.
