EPOXY/ACRYLATE HYBRID COATINGS FOR OPTHALMIC LENES |
摘要 |
An improved coating system for an ophthalmic lens that provides improved characteristics in the form of abrasion resistance, while also providing improved manufacturability and rapid curing as compared to prior art coating systems. The coating system is a composite coating that hybridizes both epoxy and acrylate coating materials into a single coating system. The coating material of the present disclosure includes at least a poly (meth) acrylate polymer, a polymerizable monomer containing at least one epoxy group and a cationic polymerization initiator. The coating may be further enhanced by the addition of colloidal nano-silica particles that serve to reinforce the mechanical properties of the coating system without compromising the overall transparency and optical clarity of the coating.
