    摘要: A method for measuring volatile organic compounds includes loading glass containers into an oven, heating the oven, purging the oven with dry clean air, collecting a volumetric portion of an oven exhaust, trapping volatile organic compounds from the volumetric portion, and measuring the volatile organic compounds trapped in the trap. The one or more glass containers are in-tact while measuring the VOCs of the coated glass container. An apparatus includes an oven having an interior volume that is capable of holding one or more in-tact glass containers, a flow meter fluidly connected to the first trap, and a pump fluidly connected to the flow meter. The first trap collects volatile organic compounds from a volumetric portion of the oven exhaust gas. The pump controls a flow rate of the volumetric portion of the oven exhaust gas across the first trap.

    摘要: An aqueous formulation and method of making an ultraviolet light blocking coating from an aqueous formulation having from greater than or equal to 15 wt % to less than or equal to 65 wt % water, from greater than or equal to 30 wt % to less than or equal to 70 wt % metal oxide particles, and from greater than or equal to 5 wt % to less than or equal to 35 wt % aminoalkylsilsesquioxane oligomers. An optical device including a housing, a lens element, potting material positioned between the lens element and the housing, and an ultraviolet light blocking coating positioned between the lens element and the potting material. The ultraviolet light blocking coating has from greater than or equal to 30 wt % to less than or equal to 90 wt % metal oxide particles and from greater than or equal to 10 wt % to less than or equal to 70 wt % silsesquioxane.
