A vehicle surface treatment composition includes a colloidal inorganic oxide dispersion or a soluble silicate amenable to application to both porous and semi-porous vehicle hard surfaces to provide a multi-surface protective barrier that imparts water repellency and weathering protection properties to the vehicle finish. The composition provides a hard surface cleaning and forms a coating to the applied surface. The compositions provide treated surface properties that include keeping clean, scratch/mar defense, bug repellency, UV protection, and weathering defense. The compositions create treated surfaces that are highly smooth and lubricious which provide enhanced protection, while achieving a high luster finish with a streak free appearance. The composition is readily applied through resort to a conventional trigger spray application, propellant aerosol, or a sponge or cloth for wipe application onto the vehicle surface.

Disclosed embodiments concern a composition comprising a diatom frustule and two or more photocatalytic nanoparticles dispersed on the surface of the frustule. Also disclosed are embodiments of a method for making the composition. The nanoparticles are dispersed such that they are separate and not in physical contact with each other. An average distance between the nanoparticles may be from greater than 0 nm to 100 nm. The nanoparticles may comprise a dopant material. Paint compositions comprising the diatom frustule compositions are also contemplated. The diatom frustule composition may be useful for removing and/or degrading volatile organic compounds, such as those present in the atmosphere.

Described herein are coatings which impart oil, grease, and water resistance to various materials, such as paper, paperboard and polymeric materials. Such coatings may be applied as barrier coatings to the substrate materials in order to inhibit and prevent the transmission of oil, grease and water; that is, to prevent oil, water grease from passing into and/or through the substrate material. The coatings include an acrylic-based polymer latex, a styrene-butadiene rubber latex, a styrene-acrylic resin solution, a large particle size wax, and optionally, a small particle size wax. Also disclosed herein is a process of preparing the coatings. Also disclosed are products to which the coatings have been applied in order to impart oil, grease and/or water resistance, and processes for preparing such products.

The present invention relates to a coating composition and method of manufacturing said coating composition. The coating composition is a two-component coating composition for construction surfaces. The present coating composition is effectively bonded to the surface without an additional application of intermediate layer overcoming the existing problems associated with conventional concrete surface treatment methods.

This disclosure relates to a glucose-sensing electrode including a nanoporous metal layer and a maltose-blocking layer formed over the nanoporous metal layer. The nanoporous metal layer is capable of oxidizing both glucose and maltose without an enzyme specific to glucose or maltose in the glucose-sensing electrode. The maltose-blocking layer has porosity that permits glucose to pass therethrough and inhibits maltose from passing therethrough toward the nanoporous metal layer.

Hardcoat comprising a binder, and in a range from 15 to 95 volume % nanoparticles, wherein at least a portion of the nanoparticles are functionalized by free radical reactive silane and cyano group containing silane. Hardcoats described herein are useful, for example, on portable and non-portable information display articles (e.g., illuminated and non-illuminated display articles).

The invention provides a water- and oil-repelling member having a primer layer as a first layer on at least one surface of a base material and further having a water- and oil-repelling layer as a second layer on the outer surface of the primer layer. The primer layer comprises a layer containing nano-diamonds and having a film thickness of 0.5 to 500 nm, the main component being an organic silicon compound having a plurality of silanol groups within a molecule. The water- and oil-repelling layer comprises a layer having a film thickness of 0.5 to 30 nm, the main component being a cured product of a hydrolysable fluorine-containing compound. The water- and oil-repelling member can stably and simply impart a water- and oil-repelling coat having excellent abrasion resistance to various base materials. In addition, the primer layer and the water- and oil-repelling layer can be coated even in a room-temperature (25° C.) process.
