Weight loss cured adhesive

While this paper reports only preliminary findings. It does Illustrate the usefulness of photocalorimetry to define optimum cure conditions for UV curable adhesives. In addition, once the mechanical spectrum of fully cured adhesive has been mapped, mechanical spectroscopy can be used to monitor cure efficiency. In this paper we have not explored the molecular weight Implications of Incomplete polymerization. Preliminary evaluation of loss and storage modulus data would suggest that time-temperature superposition may be necessary to evaluate molecular welght/degree of cure relationships and terminal, plateau, and transition zones (4). 

Thermogravimetric analysis (TGA) is a technique whereby weight changes in a sample can be continuously monitored with respect to temperature. TGA can be used to look at weight losses associated with the polymerization of an adhesive product, or to determine percentage volatiles released from a cured product during thermal cycling.
