EBECRYL® 604

EBECRYL® 604 is a bisphenol A epoxy diacrylate oligomer diluted with 20% of 1,6 hexanediol diacrylate (HDDA) monomer. It is known for its light color, low odor, low viscosity, and fast cure response. When cured by ultraviolet light (UV) or electron beam (EB), EBECRYL® 604 forms films with high gloss, high surface hardness, and excellent solvent resistance typical of an epoxy resin. Here's an overview of its properties and applications:
