To provide a production method for obtaining a coated article provided with a coating film having excellent weather resistance by using a powder coating material. A method for producing a coated article, which comprises applying a powder coating material comprising a fluororesin (A), a non-fluororesin (B) and a metallic pigment (C) to the surface of a substrate, and heating the substrate having the powder coating material applied, to a temperature of at least the glass transition temperature of the fluororesin (A) and the non-fluororesin (B), followed by cooling, to form a coating film on the substrate surface, and which is characterized in that the content of the metallic pigment (C) is from 0.7 to 23 mass % to the total amount of the powder coating material, the PCI value of the coating film is at least 6, and the flip-flop value is at least 1.2.

A high gloss acrylonitrile butadiene styrene (ABS) sheet includes an ABS substrate, an intermediate film of poly(3,4-ethylenedioxythiophen)-polystyrene sulfonate formed on top of the ABS substrate, and a fluorinated resin film of poly(vinylidene fluoride-trifluoroethylene) formed on top of the intermediate film. A method of preparing the high gloss ABS sheet is also disclosed.

A fluororubber molded product according to the present invention is obtained by the steps of molding and crosslinking a fluororubber composition and thereafter immersing the composition in a fluorocarbon or an aqueous solution containing a fluorocarbon at a concentration of not less than 10% by volume.

Provided is a coating composition containing: water; a water-soluble organic solvent that has a flash pint of at least 80 C. and not more than 200 C. and dissolves a fluorine resin; a fluorine resin; hydrophilic silica particles; and hydrophobic silica particles. The hydrophilic silica particles are preferably contained in the coating composition in an amount of at least 0.001 mass % and not more than 1 mass %. The average particle diameter of the hydrophilic silica particles is preferably at least 5 nm and not more than 30 nm.

This application relates to omniphobic materials which are physically and chemically modified at their surface to create hierarchically structured materials with both nanoscale and microscale structures that provide the omniphobic properties. Methods of making such omniphobic surfaces with hierarchical structures and uses thereof, including as flexible films that repel contaminants are also disclosed in the application.

A method for shaping a coating on a razor blade, and a razor blade produced using the aforesaid method, are provided. The method includes the steps of a) providing a razor blade having a tip end defined by at least one tip surface and a cutting edge; b) applying a surface coating having a first thickness on at least one tip surface; and c) shaping the surface coating on the at least one tip surface to have a second thickness using a fluid stream, which second thickness is less than the first thickness.

A high gloss acrylonitrile butadiene styrene (ABS) sheet includes an ABS substrate, an intermediate film of poly(3,4-ethylenedioxythiophen)-polystyrene sulfonate formed on top of the ABS substrate, and a fluorinated resin film of poly(vinylidene fluoride-trifluoroethylene) formed on top of the intermediate film. A method of preparing the high gloss ABS sheet is also disclosed.

Anti-reflective (AR) coatings and methods for applying AR coatings to substrates, such as optical lenses. The coating may include a polyurethane base layer and a fluoropolymer top layer. The base layer may protect the underlying substrate, promote adhesion between the top layer and the underlying substrate, and achieve index-matching with the underlying substrate. The method may involve an inexpensive and efficient solution coating process.
