The present invention relates to a process for producing an antimicrobial coating on a glass substrate, an antimicrobial coated glass substrate prepared by the process and use thereof, the process comprising the steps of: i) providing a glass substrate having a first surface and a second surface; ii) providing a silicon containing solution and a particle containing solution; iii) mixing together the silicon containing solution and the particle containing solution to form a silica coating composition; iv) contacting at least said first surface of the substrate with the silica coating composition to deposit a layer of silica on the glass substrate; and iv) curing the silica coating composition deposited on the glass substrate to form a silica matrix coating layer, wherein the particles are deposited on and/or within the silica matrix coating layer wherein the particles are deposited on and/or within the silica matrix coating layer in an amount of from 0.1 to 20% by weight.

Scratch-resistant coatings, especially for cooktops, and substrates or products having said scratch-resistant coatings and methods for the production thereof are described herein. More particularly, scratch-resistant coatings obtained via sol-gel approach and coated substrates having thereon a hard material layer comprising metal nitride(s) and/or metal oxynitride complexes are described, as well as the manufacturing thereof.

A method is provided to form a dust mitigation coating that also mitigates or repels water, ice, and other liquids. Techniques to coat the surfaces of equipment and items with these dust, liquid, and ice mitigation coatings, minimize or eliminate mission problems caused by dust, liquid, or ice accumulation, particularly in outer space or on another planetary body or moon. Further, the dust mitigation coatings exhibit a Lotus-like effect, making the coated surfaces ultra-hydrophobic. The present invention is also directed to techniques for improving the functioning of terrestrial-based equipment and systems where dust, liquid, or ice accumulation is a problem, such as in hospitals and other health contexts, to prevent contamination.

An apparatus for applying the film to the substrate includes a bed having a substrate placement surface and a selectively positionable tack bar, a roller support moveable over the span of the bed, and including the location of the positioning bar, and a roller rotatably supported to the positioning bar and moveable over the bed in response to movement of the roller support with respect to the bed. In another aspect, the tack bar is of the same thickness, or slightly less thick, as the substrate onto which the film is to be applied, such that a portion of the film to be applied can be secured thereto and not on the substrate before the backing is removed from additional portions of the film, such that the tack bar supports an end of the film in substantially the plane of, or slightly below the plane of, the substrate.

The applicator assembly comprises a conveyance means disposed on a frame. Further disclosed are innovative applicator heads that comprise a deformable sponge-like core surrounded by a microporous layer. The structure, when in contact with a substrate surface, deposits a uniform layer of coating solution over a large surface.
