A low infrared absorbing lithium glass includes FeO in the range of 0.0005-0.015 wt %, more preferably 0.001-0.010 wt %, and a redox ratio in the range of 0.005-0.15, more preferably in the range of 0.005-010. The glass can be chemically tempered and used to provide a ballistic viewing cover for night vision goggles or scope. A method is provided to change a glass making process from making a high infrared absorbing lithium glass having FeO in the range of 0.02 to 0.04 wt % and a redox ratio in the range of 0.2 to 0.4 to the low infrared absorbing lithium glass by adding additional oxidizers to the batch materials. A second method is provided to change a glass making process from making a low infrared absorbing lithium glass to the high infrared absorbing lithium glass by adding additional reducers to the batch material. In one embodiment of the invention the oxidizer is CeO. An embodiment of the invention covers a glass made according to the method.

An insulating unit includes a first spacer frame between first and second sheets, e.g. glass sheets, and a second spacer frame between the second sheet and a third sheet. A first surface of the first spacer frame is adhered to inner surface of the first sheet, and an opposite second surface of the first spacer frame is adhered to a first surface of the second sheet, by a moisture impervious adhesive layer. A first outer surface of the second spacer frame is adhered to a second surface of the second sheet, and an opposite second outer surface of the second spacer frame is adhered to an inner surface of the third sheet, by the adhesive layer. The first spacer frame and the second spacer frame have an offset of greater than zero.

A method is provided for applying a water repellant coating over a substrate surface. The surface is contacted with at least one coating composition including at least one perfluoroalkylalkylsilane, at least one hydrolyzable primer, e.g., a silane and/or siloxane, and at least one non-halogenated, e.g., non-fluorinated, alkylsilane. The perfluoroalkylalkylsilane and non-fluorinated alkylsilane can be selected such that the effective chain length of the non-fluorinated alkylsilane is equal to or longer than the effective chain length of the perfluoroalkylalkylsilane.

Water repellant surface treatment and treated articles

The present invention relates to a method of improving the durability of water-repellent films deposited on the surface of a substrate and to a coated article having a water-repellent film of improved durability deposited on the substrate surface. The method includes the steps of simultaneously abrasively and chemically preparing the surface to expose an increased number of bonding sites on the substrate surface by applying a dispersion including an acid solution and an abrasive material to the surface. The dispersion is then removed and the water-repellent film is formed over the prepared surface. The bonding sites react with the water-repellent film to more effectively bond the film to the substrate and thereby improve the durability of the water-repellent film. The abrading material is preferably selected from the group consisting of alumina, ceria, iron oxide, garnet, zirconia, silica, silicon carbide, chromic oxide, pumice and diamond, and the acid solution is preferably selected from the group consisting of solutions of hydrochloric acid, sulfuric acid, tartaric acid, phosphoric acid, hydrobromic acid, nitric acid, acetic acid, trifluoroacetic acid, oxalic acid and citric acid.

Water-repellent surface treatment

The present invention relates to improving the durability of water repellent films and a method for providing the film on a substrate. The water repellent film is preferably formed over the substrate by applying a water repellent composition Over the substrate which will form the water repellent film. The durability of the water repellency of the film is improved by activating the substrate with an acid prior to forming the water repellent film over the substrate.
