Title
(EN) A COMPOSITION FOR A THIN GREEN SOLAR-CONTROL GLASS
(ES) UNA COMPOSICIÓN PARA UN VIDRIO VERDE DELGADO DE CONTROL SOLAR
(FR) COMPOSITION POUR VERRE VERT MINCE DE CONTRÔLE SOLAIRE
Abstract
(EN)
The invention relates to a glass composition and to a method for the commercial production of a thin green glass having solar control properties, primarily for use in the automotive industry, as symmetrical hybrid windscreens or asymmetrical hybrid windscreens, side lights and rear windows, including a composition based on a soda-lime-silica glass, and essentially consisting of the following, in percentage by weight: 1.30 to 2.50% of the total iron expressed as Fe2O3; 15 to 40% of Fe2+ (ferrous) and 0.15 to 0.65% of FeO, expressed as Fe2O3; approx. 0.05 to approx. 0.30% of SO3; approx. 0.02 to approx. 1.0% of TiO2; approx. 0.0002 to approx. 0.03% of Cr2O3; and approx. 0.0002 to approx. 0.015% of CuO. The thin green solar-control glass has a light transmittance “A” (TLA) greater than 70%, a direct solar transmittance (TDS) of less than 51%, a total UV transmittance (TUV) of less than 40% and a total solar transmittance (TTS) of less than 63%, a dominant wavelength (λ) of 490 to 600 nm, and an excitation purity lower than 7, for thicknesses of approx. 0.7 to 3.0 mm.
