Appl. No.:

09/699681

Inventors:

David A. Russo - Norristown PA
Clem S. McKown - Glenmoore PA
Christophe Roger - Limerick PA
Jeffrey L. Stricker - Wynnewood PA

Assignee:

Atofina Chemicals, Inc. - Philadelphia PA

International Classification:

B32B 1706

US Classification:

428432, 428426, 428688, 428689, 428697, 428699, 428701, 428702

Abstract:

A solar-control glass that has acceptable visible light transmission, absorbs near infrared wavelength light (NIR) and reflects midrange infrared light (low emissivity mid IR) along with a preselected color within the visible light spectrum for reflected light is provided. Also provided is a method of producing the improved, coated, solar-controlled glass. The improved glass has a solar energy (NIR) absorbing layer comprising tin oxide having a dopant such as antimony and a low emissivity control layer (low emissivity) capable of reflecting midrange infrared light and comprising tin oxide having fluorine and/or phosphorus dopant. A separate iridescence color suppressing layer as described in the prior art is generally not needed to achieve a neutral (colorless) appearance for the coated glass, however an iridescence suppressing layer or other layers may be combined with the two layer assemblage provided by the present invention. If desired, multiple solar control and/or multiple low emissivity layers can be utilized. The NIR layer and the low emissivity layer can be separate portions of a single tin oxide film since both layers are composed of doped tin oxide.

International Classification:

B05D 5/12
H01B 1/08

US Classification:

4271263, 42725523, 2525201

Abstract:

Tin oxide having high mobility and a low electron concentration, and methods for producing layers of the tin oxide layers on a substrate by atmospheric pressure chemical vapor deposition (APCVD) are disclosed. The tin oxide may undoped polycrystalline n-type tin oxide or it may be doped polycrystalline p-type tin oxide. When the layer of tin oxide is formed on a crystalline substrate, substantially crystalline tin oxide is formed. Dopant precursors for producing doped p-type tin oxide are also disclosed.

Abstract:

A composition for coating glass by chemical-vapor deposition comprises a mixture of a tin oxide precursor monobutyltin trichloride, a silicon dioxide precursor tetraethylorthosilicate, and an accelerant such as triethyl phosphite; the composition is gaseous below 200 C. , and permits coating glass having a temperature from 450 to 650 C. at deposition rates higher than 350 Å/sec. The layer of material deposited can be combined with other layers to produce an article with specific properties such as controlled emissivity, refractive index, abrasion resistance, or appearance.
