Cement and skinning material based on a water-swellable clay, and method for producing segmented or skinned ceramic honeycomb structures

Skins and/or adhesive layers are formed on a porous ceramic honeycomb by applying a layer of a cement composition to a surface of the honeycomb and firing the cement composition. The cement composition contains a water-swellable clay, high aspect inorganic filler particles and water, and are nearly...

More Information
Summary:Skins and/or adhesive layers are formed on a porous ceramic honeycomb by applying a layer of a cement composition to a surface of the honeycomb and firing the cement composition. The cement composition contains a water-swellable clay, high aspect inorganic filler particles and water, and are nearly or completely devoid of particles smaller than 100 nm and a cellulosic polymer.
