QUESTION: Why does crystallization happen?

ANSWER:

Simply put, the liquid resin is fighting to return to its natural state, which is a solid form. Crystallization in epoxies is so common that major manufacturers have written datasheets on the subject. According to these technical bulletins, extreme temperature cycles may kick-start the creation of crystals. For example, let’s say a container of epoxy is air-shipped to Mexico City. The cold temperatures in the high-altitude airplane are followed by hot temperatures in Mexico’s capital city. Temperature cycles are just one of many potential causes. Please keep this in mind: Crystallization is not in anyone’s control and, therefore, it’s difficult to avoid.
