EBECRYL® 870 is a fatty acid modified polyester hexaacrylate. Because of the special structure of the backbone and the high acrylic functionality, EBECRYL® 870 provides the proper hydrophilic-lipophilic balance necessary for lithography, and high reactivity when cured by ultraviolet light (UV) or an electron beam (EB). It is recommended for: fast curing lithographic inks and clear varnishes, and improving lithographic behavior as an additive.
