Bertrange, Luxembourg, September 22, 2016 – A unique technology has been developed that improves the quality and reduces the time required for edge enameling of Guardian heat treatable sputtered coated glass.
In structural glazing applications, the areas of the glazing where sealant is applied normally requires adequate edge deletion. Similarly, in glazing with ‘all-glass’ corners, ceramic paint is applied to cover the structural elements such as joints. In fact, more than 90% of cut-to-size, high performance coated glass is now requested with an edge enamel (perimetrical). However, the edge enameling process is time-consuming and requires additional handling steps, resulting in long lead times. Quality issues may also arise, as often the area to be treated is too wide for conventional edge deletion devices, resulting in poor optical quality and non-uniform surfaces.
With Guardian System TEA, the material-dissolving ceramic paint (enamel) is applied directly to the sputter coating, dissolving it during the heat treatment process. The high quality Ferro enamel simultaneously fuses with the glass, creating an exceptionally strong bond and a perfectly uniform surface with excellent optical qualities. After cooling, the coating material is fully embedded in the enamel.
The efficiency of Guardian System TEA effectively reduces the number of post-processing steps into a singly process, enabling the glazing to be delivered to the customer faster, with shorter lead times.
Guardian System TEA can be applied using silk-screen printing, roller coating or manually. The technology can be used with Guardian SunGuard® or ClimaGuard® architectural heat treatable sputter coating and in combination with a number of widely used structural glazing sealants. The technology is certified ETAG 002 by the Institut für Fenstertechnik (IFT) in Rosenheim, Germany, and the AbZ of the German DIBT.
