Zusammenfassung:	An antibacterial and /or antiviral treatment composition for optical components and method of application comprises a Quaternary Ammonium Compound (QAC) that contains a silicon moiety. The SiQAC is configured to covalently bond to an optical component. The optical component may be fabricated from a glass material, a polar polymer, a polysilicate, a polyalkylsilicate, a polyzirconate, or a fluoroether or fluoroalkyl polymer. The covalent bond between the SiQAC and the material surface of the optical component endows antibacterial and / or antiviral activity to the surface of the optical component. In applying the SiQAC to the surface of the optical component using an evaporative process, a condensed form of SiQAC is deposited onto an optically active surface. Additionally, the composition can also include a thermosettable moiety instead of a hydrolyzable silicon moiety, said thermosettable moiety being selected from the group consisting of epoxy, isocyanate, and blocked isocyanate. L'invention porte sur une composition de traitement antibactérien et/ou antiviral destinée à des composants optiques et un procédé d'application comprenant un composé d'ammonium quaternaire (QAC) qui contient une fraction de silicium. Le SiQAC est conçu pour se lier de manière covalente à un composant optique. Le composant optique peut être fabriqué à partir d'un matériau de verre, d'un polymère polaire, d'un polysilicate, d'un polyalkylsilicate, d'un polyzirconate ou d'un polymère de fluoroéther ou de fluoroalkyle. La liaison covalente entre le SiQAC et la surface de matériau du composant optique confère une activité antibactérienne et/ou antivirale à la surface du composant optique. Lors de l'application du SiQAC à la surface du composant optique à l'aide d'un procédé d'évaporation, une forme condensée de SiQAC est déposée sur une surface optiquement active. De plus, la composition peut également comprendre une fraction thermodurcissable au lieu d'une fraction de silicium hydrolysable, ladite fraction thermodurcissable étant choisie dans le groupe constitué par époxy, isocyanate et isocyanate bloqué.
