A layered tetravalent metal phosphate composition (e.g., a layered zirconium phosphate composition) and a first corrosion inhibitor (e.g., cerium (III), a vanadate, a molybdate, a tungstate, a manganous, a manganate, a permanganate, an aluminate, a phosphonate, a thiazole, a triazole, and/or an imidazole) is dispersed in an aqueous solution and stirred to form a first solution. A precipitate of the first solution is collected and washed to form a first corrosion inhibiting material (CIM), which includes the first corrosion inhibitor intercalated in the layered tetravalent metal phosphate composition. The first CIM is added to a first sol-gel composition to form a first CIM-containing sol-gel composition. The first CIM-containing sol-gel composition is applied on a substrate to form a CIM-containing sol-gel layer, cured by UV radiation, and thermally cured to form a corrosion-resistant coating. One or more additional sol-gel composition may be applied on the substrate.

The present invention relates to an anti-bacterial and anti-dust coating for air ducting. In one embodiment, the anti-bacterial and anti-dust coating comprises: a polymer emulsion; a cross linking agent; a film forming agent; a filler and anti-dust agent; an anti-bacterial agent; hardener nanoparticles; a defoamer; and water. The anti-bacterial agent can be in powder or in liquid form. The coating can be applied on the inner surface of metal air ducting to reduce dust aggregation and prevent growth of bacteria, mold and mildew that causes stains and odors inside air ducting. With the aids of nanotechnology, various specific nanoparticles are added in the waterborne polymer emulsion to provide the anti-bacterial, anti-dust, anti-acid, anti-alkali, good flexibility and hardness for the coating. The product is also tested to be flame retardant and water resistance for increased safety in air ducts.

A polyimide precursor solution is provided. The polyimide precursor solution includes 100 parts by weight of a fully aromatic polyamic acid, from 5 to 20 parts by weight of silica particles, from 5 to 80 parts by weight of an alkoxysilane, and from 40 to 80 parts by weight of a solvent.

Provided is an anti-fogging coated transparent article including an anti-fog film, the anti-fog film being a single-layer film containing a water-absorbent resin, a hydrophobic group, and a metal oxide component. The hydrophobic group is a chain or cyclic alkyl group having 1 to 30 carbon atoms, preferably a linear alkyl group having 6 to 14 carbon atoms, in which at least one hydrogen atom is optionally substituted by a fluorine atom. The hydrophobic group is bonded directly to a metal atom of the metal oxide component. The anti-fog film contains, for example, the metal oxide component in an amount of 0.01 to 60 parts by mass and the hydrophobic group in an amount of 0.05 to 10 parts by mass per 100 parts by mass of the water-absorbent resin. The water-absorbent resin is, for example, polyvinyl acetal.
