basic information
UV curing has recently become widely used as a fast and economical surface processing technology that contributes to environmental conservation. It is fundamentally a simple technology, involving only the selection of light sources and formulations, as well as the choice of application fields. Therefore, it is not a difficult technology for newcomers to utilize. However, those who do not have a good understanding of the basic principles of this technology may encounter unexpected difficulties. In this course, we will provide a detailed introduction to UV radical curing as the foundation of UV curing technology, from a practical standpoint. Specifically, we will discuss important considerations regarding light sources and the selection methods for curing formulations in relation to their applications. Furthermore, we will explain the challenges of oxygen inhibition, curing shrinkage, and yellowing, along with their causes and countermeasures. We will also cover recent topics such as the significance of selecting UV-LEDs, thiol-ene UV curing methods, and hyperbranched polymers. Additionally, we will introduce the basics and current status of UV cationic curing and UV anionic curing in comparison to UV radical curing.
