EBECRYL® 838 is a polyester hexaacrylate known for its fast cure response and moderate viscosity. When cured by ultraviolet light (UV) or electron beam (EB), films of EBECRYL® 838 display notable characteristics such as good abrasion and scratch resistance, solvent resistance, and hardness. This oligomer is used in radiation-curable coatings and finds applications in offset and lithographic printing, as well as other specialty coatings. Various application methods, including curtain coating, dip coating, gravure coating, roller coating, and slot-die coating, are suitable for utilizing EBECRYL® 838 in different coating processes.
