A method and equipment to form a digital print by applying dry colorants on a surface of a panel, bonding a part of the colorants with a binder and removing the non-bonded colorants from the surface. The method of forming a digital print on a surface of a panel includes displacing the panel under a digital drop application head, applying a liquid binder with the digital drop application head on the surface; applying colorants on the liquid binder and the surface; bonding a part of the colorants to the surface with the liquid binder; removing non-bonded colorants from the surface such that a digital print is formed by the bonded colorants; and applying heat and pressure on the panel, the surface and the bonded colorants such that the colorants are permanently bonded to the surface.

A heating component and method of producing a heating component. The heating component includes a coating system applied to a substrate; and a sealant applied as at least one of a continuous or closed layer over the coating system.

A compressor includes a housing, and an anticorrosive coating covering a surface of the housing. The anticorrosive coating includes a base layer applied on the surface of the housing, and a surface layer applied on the base layer. Both the base layer and the surface layer are organic coatings. Thus, the housing of the compressor is effectively separated from the external environment by means of the two organic coatings, so as to ensure that the compressor is not corroded; moreover, the anticorrosive coating does not contain a metal coating, thereby preventing the problem of the compressor being severely corroded due to an exposed metal coating.

Disclosed is a shingle that uses a polyester sheet as a substrate layer. The polyester sheet has a sufficient weight and is needled and formed from two layers to resist shrinking upon cooling after the heated asphalt layers are applied to the polyester substrate sheet 102. In addition, additives may be included in the asphalt to lower the softening point temperature of the asphalt that further reduces shrinking of the polyester substrate 102 or allows other polymers that are more fire retardant to be used. Fire retardants can be placed in the polyester sheet fibers, placed in the bonding agent for the polyester fibers, or the polyester sheet can be coated with the fire retardant. Alternatively, or in addition to treating the polyester sheet 102 with fire retardant, fire retardant materials such as ammonium sulfate can be added to the liquid asphalt prior to application of the asphalt layers.

The invention relates to a process for the manufacturing of an optical article comprising forming a multilayered coating on at least one face of an uncoated or coated substrate,and forming on the outermost layer of said multilayered coating, a layer-by-layer (LbL) coating exposed to environment, said LbL coating comprising at least two bilayers, each bilayer being formed successively by: i) applying a first layer composition comprising at least one compound A having a first electrical charge; ii) applying, directly onto the first layer resulting from i), a second layer composition comprising at least one compound B having a second electrical charge, said second electrical charge being opposite to said first electrical charge; iii) repeating at least once steps i) and ii), with the provisos that: -each of compounds A and B is independently chosen from polysaccharide polymers and colloids of metal oxide such as TiO.sub.2 and ZrO.sub.2 or silicon oxide, with the proviso that at least one of the compounds A and B is a polysaccharide polymer, -each of said compounds A and B is positively or negatively charged respectively, and d) crosslinking the first and second layers of said bilayers of the LbL coating by treatment with an aqueous composition comprising at least tetrakis(2-hydroxyethyl) orthosilicate (THEOS) as crosslinking agent to induce chemical linkages between compounds A and B. The invention also relates to the optical substrate obtained according to this process.

A method of forming a digital embossing on a surface by bonding hard press particles to a carrier. A liquid binder pattern is applied on the carrier by a digital drop application head. Hard press particles are applied on the carrier and the binder pattern such that some hard press particles are bonded to the carrier by the liquid pattern and non-bonded press particles are removed. The carrier with the bonded hard press particles is pressed to the surface and an embossing is formed when the carrier with the hard press particles is removed.

A semiconductor structure is provided including an electrically-conducting substrate and a layer of a two-dimensional material. The structure further includes a solid organic spacer layer arranged between the electrically-conducting substrate and the layer of the two-dimensional material.

An overlay film-forming composition used to cause phase separation to a block copolymer-containing layer formed on a substrate, the composition including: (A) a copolymer that includes (a) a unit structure derived from maleimide structure and a unit structure derived from styrene structure; and (B) an ether compound having 8-16 carbon atoms as a solvent. The overlay film-forming composition exhibits good solubility with respect to a hydrophobic solvent, and is able to induce vertical alignment of a block copolymer without causing dissolution, swelling, and the like of the block copolymer-containing layer formed on the substrate.
