Optimisation of moisture barrier properties using UV/EB curing resins

The use of UV/EB technology in developing applications such as photovoltaic and flat panel displays demands improved properties in key application parameters such as moisture vapour transmission. Molecular weight, acrylate functionality, solubility parameter and resin backbone have all a direct impact on the efficiency of the barrier coating or adhesive. This paper covers the barrier test performance of several monomers and oligomers and demonstrates that a correlation can be drawn between the physico-chemical properties of the tested materials and the obtained barrier performance.
