SINOMER® BPEFDA (Bisphenol Fluorene Ethoxylate Diacrylate, CAS 161182-73-6) is a difunctional acrylate monomer containing a rigid fluorene backbone and flexible ethoxy chains. It offers exceptionally high refractive index (>1.600), high hardness, and excellent chemical resistance. The monomer is supplied as a blend with OPPEA (≤50%) to optimize handling and reactivity. SINOMER® BPEFDA is specifically designed for UV‑curable systems where high clarity and high refractive index are required, such as optical films, advanced coatings, inks, and adhesives.
