The present disclosure relates to agents, compositions, and methods for inhibiting corrosion in various substrates, for example in metal substrates. The present disclosure also relates to compositions for inhibiting corrosion comprising at least one organic heterocyclic compound and at least one metal salt or mixed metal salt selected from rare earth, alkali earth and transition metals.

The present invention pertains to a coating composition based on a specific epoxy-functional siloxane oligomer and an amine-functional polyorganosiloxane. The coating composition is suitable for use on substrates subjected to outdoor conditions, in particular conditions where a high durability, a high UV resistance, and good anti-corrosive properties are required.

A powder composition including a resin and from 5% to 70%, by weight based on powder composition weight, of a corrosion-inhibiting pigment, optionally including from 0% to 65%, by weight based on powder composition weight, zinc, the composition being substantially free from pigment providing a metallic effect is provided. The corrosion-inhibiting pigment may be present in amounts of up to 50%, by weight based on powder composition weight, for example, up to 35%. A method for coating a substrate with the powder composition and the coated substrate so formed are also provided.

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.

A coated metal pipe for use as an automotive fluid transport tube, including a tubing formed into a circular cross sectional profile. An intermediate layer applied over said tubing. An outer paint topcoat incorporating a graphene-derivative applied over said intermediate layer providing superior corrosion resistance in addition to chemical and abrasion resistance.

A curable coating composition includes: (a) a binder having a film-forming resin with at least two functional groups, and (ii) a curing agent reactive with the functional groups of the film-forming resin; and (b) solid vulcanized rubber particles that are unreactive with the binder. The curable coating composition is a solid particulate powder coating composition. Multi-layer coating systems and methods of preparing the curable coating composition are also included.

The present invention is directed towards curable film-forming coating compositions comprising metal particles; an alkaline earth metal compound comprising an alkaline earth metal oxide, an alkaline earth metal carbonate, an alkaline earth metal hydroxide, an alkaline earth metal sulfate, an alkaline earth metal monocarboxylate, an alkaline earth metal phosphate, or combinations thereof; and an organic film-forming binder. Also disclosed are methods of making curable film-forming coating compositions, methods of coating substrates, and coated substrates resulting therefrom.

The composition described herein for the prevention of corrosion includes sacrificial metal particles more noble than a metal substrate to which the composition contacts, carbonaceous material that can form electrical contact between the sacrificial metal particles, and means for providing an anticorrosion coating material for the metal substrate. The composition can form a coating on a metal substrate surface.
