The present invention describes a coating with lubricating and anti-scratch properties, comprising glycidoxypropyltrimethoxysilane and phenyltriethoxysilane. The present invention further describes a varnish product for producing such coating and a glass product, in particular a pharmaceutical primary glass container having such coating. Last, but not least, a method is disclosed for protecting a glass surface.

A nano-composite material for coating glass, as well as methods of its manufacture and use, are disclosed. The composite may be composed of a first metal oxide bridging a silicone oil moiety and an anionic surfactant moiety, and a second metal oxide bound to the silicone oil moiety. The composite may be fabricated by heating a first metal oxide and a second metal oxide with silicone oil, followed by the addition of a mixture of the surfactant and an oxidizing solution. The composite may be mixed with a suitable solvent and applied to a hot glass sheet. A glass coated with such a composite may transmit visible light, absorb some ultraviolet light, and reflect some near infrared light. The optical characteristics of the coated glass may be used to reduce heat in a glass-enclosed area by reducing the amount of infrared and ultraviolet light transmitted through the glass.

A method of manufacturing a microarray substrate having improved reliability and mass-production properties uses a vapor of a surface-reforming material, and includes washing a base substrate, supplying the vapor of the surface-reforming material into a container to which the base substrate is provided, and coupling the vapor of the surface-reforming material to a surface of the base substrate to form a self-assembled monolayer.

A coated glass element includes: a glass surface; and a coating that coats at least part of the glass surface. The coating includes at least one layer. The at least one layer of the coating fulfills the following parameter: [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.−].sub.20/[Si.sub.2C.sub.5H.sub.15O.sub.2.sup.−].sub.80≥1.0. [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.−].sub.20 are counts of [Si.sub.2C.sub.5H.sub.15O.sub.2] ions, measured by a time-of-flight secondary ion mass spectrometry (TOF-SIMS), at 20% of a time a sputter gun beam needs to reach the glass surface and [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.−].sub.80 are counts of [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.−].sub.80 ions, measured by a TOF-SIMS, at 80% of a time a sputter gun beam needs to reach the glass surface.

The present invention provides, in various embodiments, compositions and methods for strengthening glass without heat or chemical processing of the glass itself. The compositions of the present invention are emulsions comprising polymer colloid particles that are functionalized with an organosilicon compound. The polymer colloid particles can fill surface defects in the glass due to their size being smaller than the surface defects, and the functional groups thereon can react with the surface of the glass to anchor the particles in the defects.

A glass ceramic item, intended in particular for use with at least one light source and/or at least one heating element, includes at least one substrate, such as a plate, made of glass ceramic, and having at least one light region. The substrate is coated with respect to the region with a paint consisting of at least one silicone resin and pigment(s). The content of the pigment(s) are greater than or equal to 1% and less than 10% by weight of the paint. A method for producing such an item is also included.

Glass flakes of the present invention include glass flake substrates and a coating covering at least a portion of the surface of each of the glass flake substrates and composed of a binder. The binder includes a lubricant other than silicone, or a lubricant and an aminosilane. The proportion of the lubricant in the binder is 30 mass % or less.

A coating composition is disclosed comprising: (i) a non-zwitterionic compound comprising sulfonate-functional groups and (a) alkoxysilane groups and/or (b) silanol-functional groups; (ii) alcohol and/or water; and (iii) a tetraalkoxysilane, oligomers thereof, lithium silicate, sodium silicate, potassium silicate, silica, or combinations thereof.

The present invention concerns a method comprising the steps of: introducing a substrate comprising a surface to be coated in a low-pressure reaction chamber; exposing said surface to a plasma during a treatment period within said reaction chamber; ensuring a stable plasma ignition by applying a power input, characterized in that the power input is continuously strictly higher than zero Watt (W) during said treatment period and comprises at least a lower limit power and at least an upper limit power strictly larger than said lower limit power, thereby obtaining a substrate with a coated surface. The present invention further concerns an apparatus for treating a substrate with a low-pressure plasma process and a substrate treated as such.
