Invisible-fingerprint coatings and process for forming same
A process for forming a coating on a substrate comprises forming a non-fluorinated alkyl silane hydrolysate polymer and applying the non-fluorinated alkyl silane hydrolysate polymer to a surface of the substrate. The formed invisible-fingerprint coating can have an initial oil angle less than 50.
Slip agent for protecting glass
This disclosure features use of a paper or polymer film that includes a slip agent that can transfer to its surfaces. Once the paper or film is pressed against a glass sheet, this will leave a thin surface roughness of slip agent that can prevent or reduce glass surface scratches from other surfaces or particles during shipping or finishing (e.g., cutting to size, conveyance of glass), thereby improving the yield of glass shipments between glass forming plants and customers. The thin discontinuous layer of slip agent remaining on the glass surface can be washed off easily in subsequent washing processes. The paper or film can have the slip agent imbibed within the paper or coated on it as a surface member.
Layered transparent conductive oxide thin films
Transparent conductive oxide thin films having a plurality of layers with voids located at each interface. Smooth TCO surfaces with no post growth processing and a largely tunable haze value. Methods of making include applying multiple layers of a conductive oxide onto a surface of a substrate, and interrupting the application between the multiple layers to form a plurality of voids at the interfaces.
Optical article comprising a surfactant-based temporary antifog coating with an improved durability
The present invention relates to an optical article comprising a substrate coated with a coating preferably comprising silanol groups on its surface and, directly contacting this coating, an antifog coating precursor coating, said precursor coating preferably having a static contact angle with water of more than 10 and of less than 50 and being obtained through the grafting of at least one organosilane compound possessing a polyoxyalkylene group and at least one silicon atom bearing at least one hydrolyzable group, and is further coated with a film obtained by applying a composition containing at least one surfactant of formula F(CF.sub.2).sub.y(CH.sub.2CH.sub.2O).sub.x+1H (VIII), wherein x is an integer ranging from 1 to 14, y is an integer lower than or equal to 10, compounds of formula (VIII) in which y=6 representing at least 90% by weight by weight, relative to the weight of compounds (VIII) present in the composition, so as to form an antifog coating, having preferably a static contact angle with water lower than or equal to 10.

Process for producing and processing a paste-like SiO2 composition, and the use thereof
The invention relates to a process for producing a paste-like SiO.sub.2 composition using an SiO.sub.2 slip which allows simple intermediate storage and transport conditions without the processability of the slip to give the paste-like SiO.sub.2 composition being impaired thereby. According to the invention, it is for this purpose proposed that a homogeneous SiO.sub.2 base slip be subjected to a drying step to form a dry SiO.sub.2 composition and subsequently be processed further by means of a remoistening step to give the paste-like SiO.sub.2 composition, where the remoistening step comprises the addition of liquid to the dry SiO.sub.2 composition to form a paste-like kneadable SiO.sub.2 composition having a solids content of more than 85% by weight. The invention further relates to the use of a paste-like SiO.sub.2 composition as repair composition.
