The present invention relates to a corrosion inhibitor and a corrosion inhibiting coating provided for coating a metal, particularly but not exclusively steel. The inhibitors pigment will also protect aluminium and magnesium alloys. The corrosion inhibitor particularly protects a sacrificial coating such as zinc or zinc alloy on galvanised steel, which in turn therefore provides improved corrosion resistance to the underlying steel. The present invention comprises an organic cation in a cation exchange resin.

The emulsion has a pH of 6.5 to 8.0. In the slurry, the total of the polymer component(s) and the component (a) is 20 to 30% by mass. Of the total of the polymer component(s) and the component (a) in the slurry, the polymer component(s) is 60 to 85% by mass, and the component (a) is 15 to 40% by mass. Component (a) is carbon black having a DBP absorption amount under uncompressed conditions of 150 to 300 mL/100 g and a BET specific surface area of 35 to 140 m.sup.2/g.

A coating-forming composition for an electrical steel sheet that maintains excellent insulating properties, corrosion resistance, adhesion, and the like required in a coating for an electrical steel sheet, and exhibits excellent viscosity stability, with an increase in viscosity over time being kept gradual. A coating-forming composition for an electrical steel sheet comprises colloidal silica, a phosphate, phenylphosphonic acid or a salt thereof, and an aqueous medium.

A multilayer coating film includes a lustrous layer containing a luster material and a colored layer containing a reddish coloring agent, and having translucency. Regarding a Y value of an XYZ colorimetric system calibrated with a standard white plate, when a light incident angle is 45, Y(5) represents a Y value of reflected light measured at a light receiving angle of 5, and Y(15) represents a Y value of reflected light measured at a light receiving angle of 15, the lustrous layer satisfies the following: Y(5) is 30 or more to 700 or less; Y(15)=kY(5) (where k is a coefficient); and k is 0.01 or more to 0.3 or less. The concentration of the reddish coloring agent in the colored layer is 1 mass % or more to 17 mass % or less.

A composite film may include a first transparent substrate and a first anti-reflective coating overlying a first surface of the first transparent substrate. The first anti-reflective coating may include a first binder component and a first particulate filler component. The first particulate filler component may include hollow silica nanoparticles. The composite film may further have a VLT of at least about 94.0% and a water contact angle of at least about 70.

A method and resins for use with three-dimensional printing systems and/or other energy-curing devices to create 3-D objects having electrical conductivity. The resins comprise an initiator, a photopolymerizable agent, and a nanocarbon, particularly, single-walled carbon nanotubes. The initiator, photopolymerizable agent, and nanocarbon are mixed and agitated without fully solubilizing the nanocarbon so as to maintain the electrically conductive property.

A solvent-free composite powder comprising at least one thermoplastic material and at least one submicron nanoparticle material.

The present disclosure provides an encapsulated particle for anti-UV radiation. The encapsulated particle includes a core comprising an anti-UV agent, and a shell at least partially enclosing the core and comprising a polymer. Due to the presence of the shell, the anti-UV agent can be released into surroundings at a controlled manner. The encapsulated particle can be incorporated into coatings or articles to extend their service life.

The present invention relates to a coating composition for a flexible plastic film, and more specifically to a coating composition for producing a flexible plastic film having excellent flexibility while exhibiting high hardness. According to the present invention, the coating composition exhibits flexibility, bending property, high hardness, scratch resistance and high transparency, and hardly has a risk of damaging the film even in repetitive, continuous bending or long-time folding state, and thereby can be usefully applied to flexible mobile devices, display devices, front face and display unit of various instrument panels, and the like.
