Abstract
A method for bonding glass components using an encapsulated photo-initiated optical adhesive, and the resulting glass assemblies produced by the same. A mixture containing a catalyst and a resin is provided where at least one of either the catalyst or the resin is encapsulated. The mixture is applied to a glass component. The encapsulated catalyst may then be exposed to ultraviolet light causing the capsules to release the portions contained therein and combine to form an adhesive. A second glass component is then placed on the adhesive so that the adhesive is interposed between the glass components and the adhesive is permitted to cure. Alternatively, the mixture may be exposed to UV light after the second glass component is placed. An exemplary method uses a frame with the first glass component to create a uniform thickness of adhesive and provide a low level of optical defects.
