Polyester acrylates for improved material performance in UV/EB curing systems
Polyester acrylates are part of the acrylate crosslinkers technologies consisting of polyester acrylates, epoxy acrylates, urethane acrylates, acrylated acrylics, amine modified polyether acrylates and acrylate monomers. They are used to achieve superior mechanical properties, improve coating processes, avoid or reduce VOCs and increase the reactivity. A lot of polyester acrylates tend to have lower viscosity which makes them very compatible for many applications. They allow for a better ease of handling and formulation changes become more predictable.
Polyester acrylates are usually cured under ultraviolet light (UV) or by an electron beam (EB). Therefore, the curing process is fast and efficient, while the results gain good flexibility, toughness, yellowing resistance and surface hardness.
