Dielectric analysis as cure monitoring system for melamine-formaldehyde laminates

摘要

Combinations of aminoplastic thermosetting resins are used for the production of the majority of laminates. The binder's degree of curing is the key factor for the quality of laminates. Dielectric analysis (DEA), a method well-known for the curing characterization of coatings, represents an interesting way for online cure monitoring of aminoplastic resins. By measuring the dielectric properties, process-related variations in the curing behavior can be detected directly during the production.
