Ultraviolet (UV), Electron Beam (EB), and UV-LED, also known as energy curable technology, developed in the late 1920’s, is one of the most sustainable technologies used in manufacturing. However, temperature related viscosity variations during application can result in significant quality problems with film build, color match, surface finish, gloss, adhesion, etc. This is even more important to UV Cure coatings than it is to more conventional solventborne and waterborne systems, due to their steeper viscosity vs. temperature curves.
In this presentation we contrast the temperature critical properties of common UV coatings with their conventional counterparts and examine how these properties affect the two most common application methods: spraying and rolling. We show how to turn temperature from an adversary, working against the process, to a tool that can be utilized to assure that the outcomes of the UV coating process are both predictable and repeatable.
