The degradation of optical clarity in transparent materials poses serious challenges in applications such as automotive windshields, helmet visors, and medical devices, primarily due to fog formation. Fogging occurs when high ambient energy coincides with low surface free energy, leading to moisture condensation and light scattering. A UV-curable antifog coating was developed to address this issue, utilizing formulations that included a low-viscosity tetra-functional polyether acrylate oligomer, polyethylene glycol diacrylate, 2-hydroxyethyl methacrylate, and potassium 3-sulfopropyl acrylate (SPA) for improved hydrophilicity. The formulations were applied to polycarbonate substrates and cured under UV light. The coatings maintained over 90% light transmittance in the 300–600 nm range and reduced the water contact angle of polycarbonate from ∼74° (uncoated) to ∼22–8° depending on SPA content. Swelling ratios were moderate (25–32%), indicating a stable crosslinked hydrophilic network. Formulations containing 5–10 wt% SPA exhibited superior antifog performance without haze formation, while mechanical tests confirmed high surface hardness (4H–5H) and excellent adhesion. These findings demonstrate that the developed formulation provides a highly durable, optically transparent, and hydrophilic antifog coating suitable for advanced optical applications.
