ABSTRACT:
The invention relates to a method for rapidly setting or stiffening a soft, freshly formed body such as fragile and complex thin-walled cellular substrate to prevent damage and distortions and to preserve the integrity of the substrate during the pre-firing stages of the manufacturing process. A method is disclosed for rapidly setting such objects by impregnating the object with a rapid-setting compound for a time and at a temperature sufficient to irreversibly stiffen the object, and thereafter removing any excess compound from the object. Useful rapid-setting compounds having a high affinity for water, and having appropriate molecular blocking configuration are disclosed.
