Abstract
A hybrid coating including a mixture of an organosilane component, a metal alkoxide component and a surfactant component. A method for coating a substrate including cleaning a substrate surface, treating the surface with oxygen plasma, applying an adhesion promoter to the surface, then applying a hybrid coating to the surface and curing the hybrid coating. A method for making a hybrid coating includes preparing a mixture comprising an organosilane, a metal alkoxide and a surfactant, heating the mixture; and filtering the mixture.
Claims14
A method of replenishing a worn substrate comprising the steps of:
- cleaning a surface of said worn substrate;
- treating said surface with oxygen plasma;
- after said treating step, applying an adhesion promoter to said surface;
- after said step of applying said adhesion promoter, applying a hybrid coating mixture to said surface to form a hybrid coating, said hybrid coating including an organosilane component, a metal alkoxide component and a surfactant component;
- and
- curing said hybrid coating to restore clarity and abrasion resistance to said worn substrate;
- wherein said worn substrate is a transparent part having an optical clarity acceptable for a window;
- wherein said metal alkoxide component is present in said mixture at a molar ratio of about 75:1 with respect to said surfactant component, and after curing the hybrid coating has an initial clarity greater than 98.
