METHOD OF MONITORING EXTENT OF CURE OF A COATING

摘要

Method of measuring extent of cure of a coating comprising operating a metal-containing substrate coating operation to provide a coated metal-containing substrate; positioning an investigative apparatus near the coated metal-containing substrate; and operating the investigative apparatus to obtain an extent of cure reading, the reading corresponding to an area on the coated metal-containing substrate. Areas on metal-containing substrate with an unacceptable extent of cure reading may be identified, and a process variable of the coating operation modified. The investigative apparatus may be a spectroscopic probe.
