  • Patent number: 7955470
    Abstract: A method of decorating laminated glass is disclosed. A pigment package composition comprising a cross-linkable thermoset resin, a crosslinker capable of crosslinking the thermoset resin, and a pigment is applied to a glass substrate. The crosslinker and thermoset resin are cured at a relatively low temperature (ca. 400° F.). The use of an organic based pigment composition allows use of thinner glass sheets than with traditional ceramic enamel pigment compositions.

  • Publication number: 20110039018
    Abstract: A silver conductive coating possessing infrared absorbing properties is disclosed. The coating is made from a blend of one or more micron size silver powders and/or flakes together with carbon black, inorganic pigment, glass frit, and powdered selenium or bismuth metal. The foregoing dry ingredients are pasted with an organic vehicle, applied to a substrate, and fired at a temperature of up to 1400° F. The coating absorbs infrared radiation beyond the decomposition of carbon black, thus allowing higher firing temperatures and hence shorter firing times.

  • Patent number: 7832233
    Abstract: The present invention provides a method of making a decorated multilayer glass structure using a single firing step that includes that use of a crystallizing glass enamel composition that contains ingredients to ensure the complete burnout of the organic portion of the composition upon firing and bending of a mated pair of glass sheets. A benefit of the composition is that when applied to one sheet of a mated pair of glass sheets, it burns out completely during firing and bending of the pair. The presence of high levels of oxidizers in the composition ensures a supply of oxygen to enable combustion of the organic vehicle while firing the glass sheets and prior to the sintering of the enamel composition to only one glass sheet in a mated pair of decorated or colored glass sheets.

  • Patent number: 7527832
    Abstract: A plasma spray process for structuring self-cleaning glass surfaces and self-cleaning glass surfaces formed according to the process. Molten or heat softened particles of inorganic material are plasma spray deposited onto the surface of a substrate to create a micro-rough surface. If desired, a hydrophobic top coating layer can optionally be applied to the micro-rough surface. The micro-structured surface formed according to the invention is durable and self-cleaning.

  • Patent number: 7524531
    Abstract: The present invention involves growing diatoms on a surface for the purpose of forming nanoscale-sized siliceous structures on the surface. In accordance with the invention, diatom films are grown on various substrates, which are then fired to remove all organic material from the diatoms and produce a surface coated with intricate, nanoscale-sized structures. The nanoscale-sized structured surface is subsequently treated with a hydrophobic film-forming agent to form a structured self-cleaning surface.

  • Patent number: 6997018
    Abstract: The present invention provides a method of forming a glass article having a transparent hydrophobic surface during a glass-forming operation. In accordance with the method, a plurality of solid particles of inorganic material having an average diameter of less than about 400 nm are applied to a surface of the glass article when the glass article is at a temperature within the range of from about 700° C. to about 1200° C. The inorganic particles fuse to the surface of the glass article to form the transparent hydrophobic surface. Optionally, a fluorosilane agent can be applied to the transparent hydrophobic surface to further increase its hydrophobicity. The transparent hydrophobic surface has a nano-structured texture, which makes the surface of the glass article very hydrophobic and easy to clean.

  • Publication number: 20040202795
    Abstract: A method of screen printing and laser ablating various types of substrates is disclosed. The process may be used to make decorated auto glass with additional indicia such as serial numbers, bar codes, and the like. The substrate with the applied coating may subsequently be shape formed and/or heat strengthened to produce a final product. The invention also provides a screen and a screen printed pattern which include a portion that is subsequently laser ablated to provide specific information such as serialization. In one embodiment, the screen printed and laser ablated glass substrate is fired. In another embodiment, screen printed patterns may be laser ablated with no subsequent heat treatment required.
