An abradable powder composition is includes a metal component, a lubricant component, and a polymer component. A portion of the metal component is wrapped in the lubricant component to achieve high lubricity and abradability. The abradable powder composition can be used to form an abradable seal coating provided for use in a turbo machinery having a housing and a wheel having multiple blades. The housing houses the wheel which rotates therein. The seal coating is formed on the inner walls of housing adjacent where the wheel blades pass during their rotation. When the wheel is rotated such that the blades contact the seal coating, it is abraded to form a close fit gap. The abradable seal coating preferably does not produce significant wear of the blade tips or transfer abradable material significantly to the blade tips upon being abraded.

A particulate coating composition, and preferably a powder coating composition, comprising: (i) at least one polyester polymer; (ii) at least one hardener; (iii) at least 0.1 wt % of at least one metallic pigment; and (iv) at least one polyorganosiloxane.

Disclosed is a method to produce composite materials, which contain customized mixes of nano- and/or micro-particles with tailored electromagnetic spectral properties, structural elements based thereon, in particular layers, but also bulk materials including inhomogeneous bulk materials. In some embodiments the IR-reflectivity is enhanced predominantly independently of reflectivity for visible wavelength. The enhanced IR-reflectivity is achieved by combining spectral properties from a plurality of nano- and/or micro-particles of distinct size distribution, shape distribution, chemical composition, crystal structure, and crystallinity distribution. This enables to approximate desired target spectra better than know solutions, which comprise only a single type of particles and/or an uncontrolled natural size distribution. Furthermore disclosed are methods of manufacturing such materials, including ceramics, clay, and concrete, as well as applications related to design and construction of buildings or other confined spaces.

A coating composition includes first composite particles including an effect pigment adhered to polymeric powder and second particles distinct from the first composite particles and not adhered to the first composite particles. The second particles include a colorant including a pigment. A method for imparting an anodized appearance to a substrate and a kit for applying a coating composition to a substrate to impart an anodized appearance to the substrate are also disclosed.

A dark powder dispersion liquid including a dark pigment, composite tungsten oxide particles and a solid medium, wherein a mass ratio of the dark pigment to the composite tungsten oxide particles (mass of dark-colored pigment/mass of composite tungsten oxide fine particles) is 0.01 or more and 5 or less.

The invention relates to coated effect pigments, wherein the coating comprises a binder which is suitable for powder paints. They comprise a crystalline and an amorphous fraction which is determined by C.sup.13 NMR MAS relaxation measurements, the relaxation of the .sup.13C cores being fitted as a biexponential relaxation according to the formula (II) and the degree of crystallinity c being in a range between 40 to 85%, and relaxation having a short average relaxation time T.sub.1.sup.s and a long average relaxation time T.sub.1.sup.l, and T.sub.1.sup.l being in a range of from 65 to 130 s. The effect pigments coated according to the invention have at least one endothermic peak with a maximum from a range of T.sub.max=100 to 150° C. and an enthalpy ΔH associated with said peak from a range of 15 J/g to 80 J/g in DSC at a feed speed of 5° C./min, the enthalpy being calculated relative to the amount of the binder. The binders are applied to the effect pigment by way of spontaneous precipitation.

The present invention relates to a retroreflective powder coating composition that includes: (a) a binder including a film-forming resin; and (b) a plurality of particles in which at least a portion of the particles include particles at least partially coated with a metallic material. The coating composition has a glass plate flow of 40 mm or less before addition of the plurality of particles, and/or at least portion of the particles are further coated with an additional material that lowers a surface energy of the particles. A method of forming a coating is also disclosed.

The present invention provides a temperature-sensitive material comprising a ceramic oxide host and a luminescent dopant, wherein the material exhibits one or more phase transformations, a powder comprising the material, a method of fabricating the powder, a coating comprising the material, a method of applying the coating, and a method of determining a thermal history of the material which has been subjected to a high temperature environment.

The present invention relates to a coating composition for covering golf balls. More particularly, the present invention relates to a matte coating composition mixed with a synthetic fatty acid resin derived from dehydrated castor oil. According to the present invention, a golf ball having a matte surface can realize a uniform and fine matte appearance and ensure a field of vision to enable high-precision hitting, faithfully express desired marks of various colors, characters and patterns applied thereto, and prevent surface yellowing caused by exposure to ultraviolet rays over a long period of time.
