The basic structure of OGSOL acrylate is bisaryl fluorene, with the advantages of a high refractive index, low cure shrinkage, and high transparency. Our lineup includes OGSOL EA, the standard type, and the OGSOL EA-F series whose viscosity is reduced to improve handling performance. As photoinitiators (or thermal polymerization initiators) are added to these products, it is easy to cure them by UV irradiation (or heating).
