Starch-based alkaline curing corrugating adhesives containing, as crosslinking agent, the reaction product of a ketone, formaldehyde and a secondary amine

摘要

Starch-based alkaline curing corrugating adhesives, containing a novel crosslinking agent comprising the reaction product of a selected ketone, formaldehyde and a secondary amine, are useful in the manufacture of corrugated paperboard. These adhesives are characterized by their economy, their superior overall stability and their excellent wet strength performance.
