Abstract: The invention provides method for preparing an epoxy-carbon nanomaterial coating which includes a base of a two-pack epoxy coating material, a hardener of the two-pack epoxy coating material and about 0.0125 wt % to about 0.2 wt % of carbon nanomaterial. The invention also provides a method for preparing the epoxy-carbon nanomaterial coating. More specifically, the invention provides a method for preparing epoxy based coating materials as anti-corrosive coating composition.

Abstract: The invention provides a method for preparing an epoxy based coating composition. The method includes preparing a first dispersion including one or more colorants, one or more fillers and an epoxy based paint work material dispersed in a first portion of one or more solvents. The first dispersion is prepared by dispersing the one or more colorants and the one or more fillers in the epoxy based paint work material dispersed in the first portion of the one or more solvents. The method further includes preparing a second dispersion including one or more types of carbon nanotubes, a second portion of the one or more solvents and a hardener. The second dispersion is prepared by dispersing the one or more types of carbon nanotubes and the second portion of the one or more solvents in the hardener. Additionally, the method includes mechanically mixing the first dispersion and the second dispersion.

Abstract: The invention provides a method for preparing a Polyurethane-Carbon Nanotube (PU-CNT) based coating composition. More specifically, the invention provides a method for preparing a PU-CNT based anti-corrosive coating composition. The method comprises preparing a dispersion comprising one or more types of Carbon Nanotubes (CNTs). The dispersion is prepared by dispersing the one or more types of CNTs in a dispersant comprising at least one polar solvent and at least one surfactant. The method further comprises mechanically mixing a hardener with the dispersion comprising the one or more types of CNTs. In addition, the method comprises mechanically mixing polyurethane with the dispersion prepared by mechanically mixing the hardener with the dispersion comprising the one or more types of CNTs.

Abstract: A radiant gas burner is provided having a casing adapted for connection with an air-gas mixing and supply system including a flux dissector and a mixer. The burner further includes a metallic mesh emitter inside the casing having lower and upper meshes. The lower mesh and the upper mesh each have porous openings. Each of the lower and upper meshes having a radius of curvature wherein the lower mesh is spaced apart from the upper mesh.
