LOW REFRACTIVE INDEX COATING COMPOSITION

摘要

Coating compositions are provided that, when cured, provide a coating with low refractive index, surface hardness, scratch resistance, abrasion resistance and good curability at low film thickness. In one embodiment, a composition is provided that comprises reactive nanoparticles free of fluorinated group, reactive nanoparticles having at least one fluorinated group, and an ethylenically unsaturated urethane fluorinated component.
