  • Method for coating CRT face panels
    Patent number: 5346721
    Abstract: The present invention is directed to a cathode ray tube having a surface with reduced reflectivity and electrical resistivity and to a method for providing such reduced reflectivity and electrical resistivity. In the method of the invention, a solution of a soluble metallic cation moiety and a silane in an organic solvent is provided. The solution is applied to the surface of a cathode ray tube to provide a coating of the silane and the metallic moiety of the metallic compound on the surface. Thereafter, the cathode ray tube is cured at an elevated temperature for a period of time sufficient to convert the metallic cation moiety to a metal oxide in situ and to provide a metallic oxide in a matrix of siloxane.
    Type: Grant

  • Alkoxysilane coating for cathode ray tubes
    Patent number: 5248915
    Abstract: The present invention is directed to a cathode ray tube (CRT) having a surface with improved antistatic and antiglare properties and to a method for providing such improved properties. In the method of the invention, a solution of an alkoxyilane in a solvent system of an alcohol, chloride ion and water is provided. The solution is applied to the surface of a cathode ray tube to impart antiglare and antistatic properties to the surface. Thereafter, the CRT with the saline applied is cured at an elevated temperature for a period of time sufficient to cause the saline to react and be converted to a siloxane.

  • Chlorinated silane and alkoxysilane coatings for cathode ray tubes
    Patent number: 5248916
    Abstract: The present invention is directed to a cathode ray tube (CRT) having a surface with improved antistatic and antiglare properties and to a method for providing such improved properties. In the method of the invention, a solution of a silane selected from a chlorinated silane and an alkoxysilane in a solvent system of on alcohol and chloride ion is provided. The solution is applied to the surface of a cathode ray tube to impart antiglare and antistatic properties to the surface. Thereafter, the CRT with the silane applied is cured at an elevated temperature for a period of time sufficient to cause the silane to react and be converted to a siloxane.

  • Cathode ray tube antiglare coating
    Patent number: 5150004
    Abstract: A cathode ray tube (CRT) having a surface with reduced gloss and reflectivity and a method for providing such reduced gloss and reflectivity. In the method of the invention, a solution of a silane and a saturated hydrocarbon in a solvent system of an alcohol and water is provided. The solution is applied to the surface of a cathode ray tube to impart antiglare properties to the surface. Thereafter, the CRT with the silane applied is cured at an elevated temperature for a period of time sufficient to cause the silane to react and be converted to siloxane.
