Abstract: A waterborne protective coating system is disclosed that comprises at least one binder, water, and a dispersion of 2D material/graphitic nanoplatelets.

Abstract: A method of forming a liquid dispersion of 2D material/graphitic nanoplatelets in an aqueous solution is disclosed. The method comprises the steps of (1) creating a dispersing medium; (2) mixing the 2D material/graphitic nanoplatelets into the dispersing medium; and (3) subjecting the 2D material/graphitic nanoplatelets to sufficient shear forces and or crushing forces to reduce the particle size of the 2D material/graphitic nanoplatelets using a mechanical means. The liquid dispersion comprises the 2D material/graphitic nanoplatelets, at least one grinding media, water, and at least one wetting agent, and that the at least one grinding media is water soluble or functionalised to be water soluble.

Abstract: A tiecoat coating composition for use in a coating system for a metallic substrate comprising at least three coating layers is disclosed. The system has a primer coating layer which overlies the metallic substrate, a tiecoat coating layer which overlies the primer coating layer, and a finish coating layer which overlies the tiecoat coating layer. The primer coating layer is formed from a primer composition, the tiecoat coating layer is formed from a tiecoat composition, and the finish coating layer is formed from a finish composition. The primer composition comprises a primer carrier medium and a primer corrosion inhibitor in which the primer inhibitor has a galvanic cathodic mechanism. The finish composition is formulated to give a predetermined surface texture and appearance. The tiecoat composition comprises a tiecoat carrier medium and a tiecoat corrosion inhibitor. The tiecoat corrosion inhibitor has a barrier mechanism.

Abstract: A composition comprising a carrier medium, a first corrosion inhibitor, and a second corrosion inhibitor having a barrier mechanism. The first corrosion inhibitor comprises at least one of an ion exchanged pigment, a silica, a calcium exchanged silica, an oxyaminophosphate salt of magnesium, and/or a mixture of an organic amine, a phosphoric acid and/or an inorganic phosphate and a metal oxide and/or a metal hydroxide, and the second corrosion inhibitor comprises one or more 2D material platelets in which the 2D material platelets comprise: nanoplates of one or more 2D materials and or nanoplates of one or more layered 2D materials and or graphite flakes in which the graphite flakes have one nanoscale dimension and 35 or less layers of atoms.
