A coating composition contains 25 to 35 parts by weight urethane synthetic resin solution, acrylic resin solution, or epoxy resin solution; 5 to 35 parts by weight urethane pigments, acrylic or epoxy pigments; 10 to 20 parts by weight PE-thermoplastic resin beads, phenol resin beads, melamine resin beads, epoxy resin beads, polystyrene resin beads or glass beads; 40 to 52 parts by weight organic solvents comprising urethane thinner and toluene; and 2 to 4 parts by weight curing agent, forms a coating sheet which can be attached to public or private installation, such as walls, poles, street lights, or traffic lights, to prevent adhesion of unlawful or unwanted materials on the installation, and can be provided with color tones same as those of the private or public installations in order not to defile the appearance of the street.

A coating composition includes: (i) a film-forming resin; (ii) an infrared reflective pigment; and (iii) an infrared fluorescent pigment or dye different from the infrared reflective pigment. A multi-layer coating including the coating composition, and a substrate at least partially coated with the coating composition is also disclosed. A method of detecting an article at least partially coated with the coating composition is also disclosed.

A hardcoat film has a support, a first cured layer, and a second cured layer in this order in which the first cured layer is formed of a curable composition for forming a first cured layer containing a polymerizable compound 1 having a radically polymerizable group and a polymerizable compound 2 having a cationically polymerizable group and a radically polymerizable group, the second cured layer is formed of a curable composition for forming a second cured layer containing a polymerizable compound 3 having at least two radically polymerizable groups, and a content of the polymerizable compound 2 with respect to a total content of the polymerizable compounds contained in the curable composition for forming a first cured layer is equal to or greater than 51% by mass.

A semiconductor package includes: a plurality of unit redistribution layers vertically stacked, each including: a first polymer layer having a first via hole pattern; a second polymer layer formed on the first polymer layer, and having a redistribution pattern on the first polymer layer and a second via hole pattern in the first via hole pattern; a seed layer covering sidewalls and bottom surfaces of the redistribution pattern and the second via hole pattern; a conductive via plug formed in the second via hole pattern; and a conductive redistribution line formed in the redistribution pattern; a connection terminal disposed on a bottom surface of a lowermost unit redistribution layer and electrically connected to the conductive via plug; a semiconductor device mounted on the unit redistribution layers with a conductive terminal interposed therebetween. Upper surfaces of the second polymer layer, the conductive redistribution line and the conductive via plug are substantially coplanar.

A composition and method for a microtexture hydrophobic or superhydrophobic coating. The microtexture coating includes a coating layer disposed on a substrate with hydrophobic or superhydrophobic particles dispersed on top of or partially embedded in the coating layer to form an outer layer. The outer layer exhibits water repellant properties. Use of the microtexture coating permits large scale, durable hydrophobic or superhydrophobic coating applications. The microtexture coating is a useful for application on wind turbines, airplanes, solar panels, windows, or cooling systems.

A silicone bond coat composition having a viscosity of less than 1,600 centistokes is applied to substantially all external surfaces of the article and then cured. A liquid silicone elastomer outer coat composition comprising a high viscosity first liquid silicone elastomer formulation and a low viscosity second liquid silicone elastomer formulation is then applied and cured to provide a protected article having a complex shape. Optimal coatings result from a careful balancing of component viscosities. In an embodiment, the first formulation has a viscosity greater than 300,000 centistokes, and the second formulation has a viscosity less than 6,000 centistokes, and the liquid silicone elastomer outer coat composition comprises from about 60 to about 40 percent by weight of the first formulation and from about 40 to about 60 percent by weight of the second liquid silicone elastomer formulation.

Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

A window for a display device includes: a base layer; a first hard coating layer on the base layer; and a second hard coating layer on the first hard coating layer and having a thickness less than a thickness of the first hard coating layer, where the first hard coating layer is between the base layer and the second hard coating layer.

A pipe lining having at least two material layers, a first elastomeric layer spray applied directly to the inside of a pipe which acts as a hydrophobic, ductile membrane, and a second rigid layer is spray applied to the first layer prior to complete curing of the first layer. One or more additional layers may be applied to the second layer to provide additional abrasion, erosion or chemical resistance to the second layer. An intermediate reinforcing layer may be disposed between the first and second layers. The first layer cures into a closed cell elastomeric foam, such that stress and other forces are not passed from the pipe to the rigid second layer.

Methods of preparing porous wood products for painting or finishing are described. The methods comprise applying to a porous wood product a UV-curable coating and curing by UV light the top UV curable coating to 70% to 95% cure, preferably 85% to 95% for spray-applied top UV curable coatings to produce a partially cured porous wood product. The methods typically further include the step of sanding the surface of the partially cured porous wood product and painting or staining, for example with a water-based or solvent-based stain or paint.
