Liquid coatings must be converted into a solid coating layer. Conventional thermal processes require energy for this purpose—for example, to evaporate solvents or water, as well as for polymerization and cross-linking.

This white paper demonstrates how electron beam curing can be used as a non-thermal process for liquid coatings on three-dimensional molded parts. It focuses on the physical fundamentals, process parameters such as dose, dose rate, and accelerating voltage, as well as the requirements for system design and coating application.

It also describes how compact, low-energy electron emitters can be integrated with industrial robots to selectively cure coatings on complex molded parts.
