EBECRYL® 3700

EBECRYL® 3700 is a bisphenol A epoxy diacrylate, which is a diacrylate ester of a bisphenol A epoxy resin. It's characterized by low odor and exceptional cure response. When cured by ultraviolet light (UV) or electron beam (EB), it forms films with high surface hardness, high gloss, and excellent chemical resistance. Here's a summary of its key features and specifications:
