Claim:
1. A monolithic support member comprising channels having a polygonal cross-section profile, with walls separating the channels from each other and the walls having a coating deposited thereon, wherein a mean thickness d C is the shortest distance between a surface of the coating of a fillet portion and a corner of the wall and wherein the mean thickness d C of the coating in the corner of said cross-section profile is smaller than or equal to a mean thickness d E of the coating on an edge of said cross-section profile plus 85 micrometer (d C ≦(d E +85 micrometer)), wherein the coating has a radius of curvature R that is at most 0.2 mm, and wherein the coating contains at least one carrier in an amount from 0.5 to 2.5 g/in 3 based on the volume of the monolithic support, wherein said monolithic support member is prepared by a method comprising: (i) providing a suspension having a viscosity in a range of from 1.5 to 5 mPas, determined by shearing the suspension at a shear rate of 100 s (ii) dispersing the suspension into a gas stream to obtain a gas stream comprising droplets having a droplet size in the range of from d (iii) directing said gas stream comprising said droplets towards the monolithic support member along an axial direction of the channels of the support.
