Abstract
Organic polymer particles are provided in a cement composition that is used to apply a skin to a ceramic honeycomb, or to bond the ceramic honeycomb to another honeycomb or another material. The presence of the organic polymer particles reduces the penetration of the cement composition through porous walls of the honeycomb. In this way, less blocking of the honeycomb cells is seen, and the reduction in thermal shock performance that is often seen when cement compositions are applied to ceramic honeycombs is reduced.
