HYBRID EPOXY-ACRYLIC WITH ZIRCONIUM OXIDE NANOCOMPOSITE FOR CURABLE COATINGS

摘要

A composition comprising: a continuous liquid phase comprising an acrylic monomer and an epoxy monomer; and a dispersed nanoparticulate comprising ZrO2 modified with an acrylic silane; and wherein the composition is transparent to visible light when coated on a lens. In addition, a method comprising the steps of: mixing an acrylic silane and a methanol-based ZrO2 sol to create a methanol-based silane-modified ZrO2 sol; then mixing at least an acrylic monomer, an epoxy monomer, and the methanol-based silane-modified ZrO2 sol to obtain the composition. The composition can be adapted for coating and curing onto another substrate, such as an ophthalmic lens.
