Emphasis on UV/EB curable acrylate based adhesives

摘要

The need for cost efficient and environmental friendly processes has continuously increased during the past years. In this context, UV/EB technology is considered as an ideal alternative to conventional methods in a variety of applications including laminating adhesives and pressure sensitive adhesives (PSA). Parameters such as the chemical nature, molecular weight of the oligomers and monomers, the photoinitiators content and the final glass transition temperature of the formulation have been demonstrated to greatly influence the process and the final performances of the adhesive. This paper describes the different physico-chemical analyses that have been developed to better understand the mechanisms governing the final adhesion of UV adhesives and how they can be used to design the formulation. The influence of the formulation on the final properties is also highlighted and will be discussed.
