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.

The antibacterial composition for glass coating of the present invention includes about 0.3 wt % to 15 wt % of copper nitrate; about 70 wt % to 95 wt % of a solvent; and about 0.1 wt % to 15 wt % of a structure former. The antibacterial composition for glass coating and antibacterial glass can increase the distribution of antibacterial particles on the surface of the coating layer, and have excellent hardness, weather resistance, and antifouling properties.

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.

A coating composition, coating glass and a method for preparation thereof, and a cooking appliance including the coating class are described. The coating composition includes a coating material and a heat conductive oxide nano powder that is 5 to 10 wt % with respect to a weight of the coating material. The coating composition provides an excellent infrared reflective function, a high transmittance, and an excellent cleaning performance.
