摘要： The present invention provides for a composition comprising a pigment, wherein the composition is suitable for coating a surface that is, or is expected to be, exposed to the sun. The pigment comprises particles that fluoresce in sunlight, thereby remaining cooler in the sun than coatings pigmented with non-fluorescent particles. The particles comprise solids that fluoresce or glow in the visible or near infrared (NIR) spectra, or that fluoresce when doped. Suitable dopants include, but are not limited to, ions of rare earths and transition metals. A coating composition includes: (i) a film-forming resin; (ii) an infrared reflective pigment; and (iii) an infrared fluorescent pigment different from the infrared reflective pigment. When the coating composition is cured to form a coating and exposed to radiation comprising fluorescence-exciting radiation, the coating has a greater effective solar reflectance (ESR) compared to the same coating exposed to the radiation comprising fluorescence-exciting radiation except without the infrared fluorescent 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 reducing temperature of an article includes applying the coating composition to at least a portion of the article.

摘要： This invention discloses a reticulated film composite and a method of fabricating a reticulated film composite suitable as a 3 dimensional porous and conductive matrix which contains up to 80% porosity and exhibits high recovery after compression. The reticulated film composite is produced by casting and drying of a slurry which exhibits a high yield stress (i.e. greater than 50 dyne/cm2) and comprised of a high MW resin dissolved in a solvent (i.e. having solution viscosity of higher than 100 cp at 5% in NMP at room temperature) and dispersed nanoparticles of carbon of high specific surface areas (i.e. greater than 1 m2/g preferably greater than 10 m2/g), examples include but not limited to conductive carbon, carbon nanotubes, graphene, activated carbon or mixture thereof. This reticulated film composite exhibits high electrical conductivity (i.e. volume resistivity of less than 10,000 Ω·cm) and superior dimensional stability even at elevated temperatures (i.e. at 140° C.). It will exhibit a recovery of height or porosity after being compressed to over 50% of its height. The composite of this invention is suitable as an electrically conductive composite, as a gas diffusion layer in a fuel cell, or as a high efficiency electrode in super capacitors

摘要： The present invention addresses the problem of providing a painted metal plate having rain-streak-stain resistance and a good appearance, and a method for producing the same. To solve this problem, the method for producing a painted metal plate includes a step for forming a coating by applying a paint containing a silicone resin and a fluorine-containing resin to the surface of a metal plate and curing the paint, and a step for performing flame treatment on the coating. The silicone resin contains 5 to 50 mol % of a silanol group with respect to the total molar mass of Si atoms.

摘要： Organopolysulfides such as organodisulfides, organotrisulfides and/or organotetrasulfides are useful stabilizers for polymer compositions, wherein the tendency of a polymer to degrade when exposed to environmental conditions such as heat, light and oxygen may be ameliorated by the incorporation of one or more of such organopolysulfides, optionally together with one or more additional stabilization additives such as a hindered phenol antioxidant, phosp(on)ite stabilizer or hindered amine light stabilizer.
