Coating compositions are disclosed that include corrosion resisting particles such that the coating composition can exhibit corrosion resistance properties. Also disclosed are substrates at least partially coated with a coating deposited from such a composition and multi-component composite coatings, wherein at least one coating later is deposited from such a coating composition. Methods and apparatus for making ultrafine solid particles are also disclosed.

The present disclosure relates to the field of anticorrosive pigments. Anticorrosive pigments are used with organic coatings to reduce the corrosion rate of the substrate metal. An anticorrosive pigment is incorporated in the topcoat of an anticorrosion coating system which greatly reduces the corrosion rate of the substrate metal in the environments of aggressive ions.

Novel formulations of inorganic, chemically bonded, phosphate alumino silicate sprayable coatings are disclosed. The disclosed coatings retain all the positive attributes of similar coatings disclosed in recent patents on corrosion and fire protection, and in addition, provide, superior surface toughness and smoothness, better abrasion and acid resistance, less erosion and longer durability with zero flame-spread coatings on wood surfaces. Being pore-free, water cannot penetrate into these coatings. Unlike the previous inorganic oxide-based phosphate coatings, the glassy phase in these coatings provides a translucent and dense surface. The component pastes are smoother to pump, do not settle or harden during storage and transport, and in addition, do not exhibit pozzalinic properties.

A coating method for a clad steel in which stainless sheets are combined on adjacent surfaces of an aluminum sheet may include preparing the clad steel, preparing a coating solution in which an epoxy resin and titanium dioxide (TiO.sub.2) powder are combined in an acrylic resin, etching the clad steel to improve adhesion property between the coating solution and the clad steel, heating the clad steel, and performing electrodeposition by immersing the clad steel in the coating solution.

A method of forming a passivated pigment slurry includes combining a resin and a pigment to form a pigment-resin slurry, wherein the pigment includes a plurality of flakes each having a surface. After combining, the method includes firstly reacting an orthosilicate and the pigment in the presence of the resin to form a coated pigment-resin slurry. The coated pigment-resin slurry includes the resin and a coated pigment including the plurality of flakes each encapsulated by a first layer formed from the orthosilicate on the surface. The method further includes, concurrent to or after firstly reacting, secondly reacting the coated pigment-resin slurry and an organosilane compound having a hydrolysable group and an organic group to coat the first layer and form the passivated pigment slurry. The passivated pigment slurry includes the resin and a passivated pigment including the plurality of flakes each coated with a second layer disposed on the first.

The present disclosure provides compositions including a carbon fiber material comprising one or more of an acyclic olefin group or a thiol disposed thereon; and a thermosetting polymer or a thermoplastic polymer. The present disclosure further provides metal substrates including a composition of the present disclosure disposed thereon. The present disclosure further provides vehicle components including a metal substrate of the present disclosure. The present disclosure further provides methods for manufacturing a vehicle component, including contacting a carbon fiber material with a carbon-containing zinc-titanium or a thiol to form a coated carbon fiber material; and mixing the coated carbon fiber material with a thermosetting polymer or a thermoplastic polymer to form a composition. Methods can further include depositing a composition of the present disclosure onto a metal substrate.

The present invention provides a sealing treatment solution free from a nickel salt. The sealing treatment solution is capable of ensuring a sealing performance comparative to that in the method using a sealing treatment solution containing a nickel salt, and ensuring that the resulting sealing-treated anodic oxide film has excellent contamination resistance. The present invention provides a sealing treatment solution for anodic oxide film of aluminum alloy, the sealing treatment solution comprising a metal salt, a pH buffer, and a surfactant, the metal salt being at least one member selected from alkali metal salts and alkaline-earth metal salts.

A coating composition and coating products made therefrom, containing modified inorganic nanoplatelets that form mesomorphic structure in a resin phase. The coating products exhibit low permeation/penetration properties, and can be used as anti-corrosion or barrier coatings.

The present disclosure relates to corrosion resistant coating compositions, kits and methods of applying the same, for use as fireproofing materials. The corrosion resistant spray applied fire resistant material contains an organic corrosion inhibitors, such as an aldonic acid, benzoic acid, or combinations thereof, to reduce or eliminate corrosion of the underlying substrate.

Minimum Federal Safety Standards for corrosion control on buried oil and natural gas pipelines stipulate that metallic pipes should be properly coated and have impressed-current cathodic protection (ICCP) systems in place to control the electrical potential field around susceptible pipes. In certain examples described herein, electrically-conductive nanocomposites can be used and provide intrinsically-safe foam materials without the dielectric shielding issues of existing materials used to physically protect and stabilize buried pipelines. As cured or formed by customary spray applications, the nanocomposite foams described herein are directly compatible with ICCP functionality wherever foam contacts the metallic pipe. Various foam compositions and their use with underground pipelines are described.
