Abstract: UV curing has win a lot of attention nowadays and also seen a lot of application in fields like coatings, inks, adhesives and electronics. It is simple, fast and environment friendly and helps save cost & time in industry. UV curing making use of cationic polymerization is even better for it can be carried out in air. So a lot of research are looking into this field and many photoreactive formulations are being investigated to check their UV curing behavior. This project studies the formulation of Epiclon HP-7200, a new high performance type epoxy resin from DIC Corporation, as the monomer, Bis-(3, 4-epoxycyclohexyl) adipate as the co-solvent and Cyracure ® UVI-6976 as the photoinitiator using the photocalorimetry (DPC). Results show that this formulation system can function well in the sense that it can be UV cured and shows a consistency of the rate constant and activation energy & collision factor. Also, the proven applicability of the two modes for the autocatalyzed analysis lays foundation for future study. The effect of the UV light intensity which will increase the reaction rate is also proven. Finally, some recommendations are given to suggest some aspects that can be further investigated, including to exam the effects of other factors, and look into the electron beam curing of this formulation.
