| description | A composition adapted for use in an in-situ coating process for coating an optical surface for ophthalmic applications. A coating composition according to the present invention includes at least one multifunctional acrylate compound which is cured onto a heated surface with controlled coating distribution in an ophthalmic injection mold. For example, the composition may include an acrylic base cured with an initiator, e.g., t-butyl perbenzoate, and may further include at least one catalyst and at least one metal salt. An acrylic base according to the present invention may include a combination of monofunctional and/or multifunctional acrylate and/or methacrylate compounds.
L'invention concerne une composition apte à être utilisée dans un procédé de revêtement in situ destiné au revêtement d'une surface optique pour des applications ophtalmiques. Selon la présente invention, une composition de revêtement inclut au moins un composé d'acrylate multifonctionnel qui est durci sur une surface chauffée avec une répartition de revêtement contrôlée dans un moule à injection ophtalmique. Par exemple, la composition peut inclure une base acrylique durcie avec un initiateur, par exemple, du perbenzoate de t-butyle, et peut en outre inclure au moins un catalyseur et au moins un sel de métal. Selon la présente invention, une base acrylique peut inclure une combinaison de composés d'acrylate et/ou de méthacrylate multifonctionnel et/ou monofonctionnel. |
