Abstract
A method of forming an inorganic oxide coating on a monolith article to produce a coated monolith article suitable for the treatment of an exhaust gas comprises spraying, as a dry particulate aerosol, inorganic particles and a silicone resin to form a coating layer. The present invention also provides an uncalcined porous monolith article for use in forming a monolith article for the treatment of an exhaust gas. The uncalcined monolith article comprises a dry particulate composition comprising inorganic particles and a silicone resin.
