Abstract
A process for frontal, alternate sealing of ducts in a ceramic honeycomb monolith includes temporarily sealing some ducts with a first, hardenable viscous composition; permanently sealing the then still vacant duct openings with a second hardenable, viscous composition. The first composition is removed during the course of hardening the second composition. The ceramic honeycomb monolith is for exhaust gas cleaning systems of internal combustion engines.
