EBECRYL® 629 is an acrylated epoxy novolac diluted with the reactive diluents trimethylolpropane triacrylate (TMPTA) and hydroxyethyl methacrylate (HEMA). When cured via ultraviolet light (UV) or electron beam (EB), EBECRYL® 629 exhibits high surface hardness, good heat resistance, low shrinkage, and good adhesion to metal, particularly copper. This resin was specifically designed for UV cure solder resist applications.
