An article transparent to radiofrequency (RF) signals includes a substrate and a coating arrangement on the substrate. The coating arrangement includes a primer applied to and in physical contact with the substrate, a topcoat applied to and in physical contact with the primer layer, the topcoat including an organic polymer material, and nanoparticles dispersed throughout one of the primer and the topcoat. A content of the nanoparticles ranges from 0.1 wt % to 10 wt %.

This disclosure concerns formulations and processes for obtaining conductive patterns of copper onto a substrate.

A water-based coating makes it possible to provide a highly water-repellent coating film and has excellent film formability. The water-based coating contains (a) a graft copolymer (A) containing a specific amount of a non-crosslinked polyorganosiloxane and a graft part and (b) a polymer (B) having a specific feature. The specific feature of the polymer (B) is that (i) an amount of the polymer (B) is a specific amount, or (ii) a complex of the graft copolymer (A) and the polymer (B) has a weight-average molecular weight that is not more than a specific value.

A waterborne coating composition which includes a film-forming binder and composite particles comprising wax and a metal oxide, such as wax encapsulated zinc oxide, provides enhanced mildew resistance.

A method is disclosed of three-dimensional (3D) free-form printing for coating free-form objects, the method including: arranging a free-form object in a Langmuir-Blodgett (LB) trough filed with a liquid, the LB trough designed based on a shape of the free-form object; arranging an LB film comprising a plurality of colloidal nanospheres on a surface of the liquid within the LB trough; and draining the liquid from the LB trough to form a self-assemble film of the colloidal nanoparticles on a surface of the free-form object.

A method of making a silver-silicalite coating on a surface of a stainless-steel substrate is provided. The method includes mixing metakaolin with an aqueous solution of NaOH to form a first mixture. The method further includes mixing silica gel and silver nitrate with the first mixture to form a second mixture. Furthermore, the method includes mixing Zeolites Socony Mobil-5 (ZSM-5) with the second mixture to form a third mixture. The method further includes hydrothermally treating the stainless-steel substrate with the third mixture to form the silver-silicalite coating on the surface of the stainless-steel substrate. The hydrothermal treatment is carried out in the absence of an organic template. The stainless-steel substrate coated with the silver-silicalite coating, prepared by the method of the present disclosure, has lower corrosion in comparison to the same stainless-steel substrate without the silver-silicalite coating.

Described herein are heat resistant inks and coating compositions that, when coated on a substrate, impart the feel of paper. The inks and coating compositions do not degrade when exposed to temperatures of 120? C. or greater.

A coating film includes a water-repellent resin having a smooth surface and a contact angle of 70 degrees or more. The coating film has a plurality of protrusions formed by the water-repellent resin, and the plurality of protrusions are scattered in the coating film and each have an end portion with a convex surface formed by cutting out a continuous region accounting for 50% or more of a spherical surface. The spherical surfaces each have an average radius of curvature of 16 ?m or less. An average distance between each ones of the plurality of protrusions adjacent to each other is less than or equal to 30 times a radius of curvature.

The invention relates to aqueous dispersions comprising multistage-prepared polymers, and also to coating material compositions comprising them, preparable by multistage polymerization of olefinically unsaturated monomers, using an emulsifier and a water-soluble initiator, under conditions of starved feed polymerization, and using particular monomer mixtures in the individual stages.

The invention also relates to a pigmented aqueous basecoat material comprising the aqueous dispersion of the invention, to the use of the aqueous dispersion of the invention in aqueous basecoat materials for improving adhesion, to a process for producing a multicoat paint system on a substrate, and to a multicoat paint system produced in accordance with the stated process.

A pelletized thermoplastic road marking material is provided in which glass dust rather than calcium carbonate is used as the filler. Such glass dust can account for up to 55 weight % of the final formulation. Glass dust is a readily available and inexpensive byproduct of glass manufacturing which otherwise has little or no commercial value. Use of the glass dust is effective if the thermoplastic composition is prepared in pelletized form and performs comparably to a thermoplastic composition having calcium carbonate filler, while producing a higher yield.
