Optimizing Pentamethyl Diethylenetriamine (PC-5) in Low-Shrinkage Epoxy Electronics Packaging

Optimizing Pentamethyl Diethylenetriamine (PC-5) in Low-Shrinkage Epoxy Electronics Packaging Abstract: Pentamethyl Diethylenetriamine (PC-5), a tertiary amine catalyst, plays a crucial role in the curing kinetics and final properties of epoxy resin systems used in electronics packaging. This article delves into the optimization of PC-5 concentration in low-shrinkage epoxy formulations, focusing on its impact on cure kinetics, glass transition temperature (Tg), coefficient of thermal expansion (CTE), mechanical…
