        Text of Abstract 
        
        NIR data can successfully be obtained from a coating curing on a rheometer plate, enabling simultaneous collection of both spectroscopic and rheological data and allowing for direct correlation of key rheological figures of merit with chemical conversion.  By combining NIR with cure rheology, we were able to obtain new insights into the relationship between chemical conversion and rheological behavior for a demonstration coating system, particularly as a function of cure temperature.
