The latest generation of Axalta Coating Systems’ Nap-Gard thermosetting epoxy powder is formulated to withstand continuous operating temperatures as high as 311°F (155°C). Nap-Gard High Tg 7-2555 is designed for use as a corrosion barrier coating for underground and sub-sea pipelines that operate in high temperatures. It can be used as a corrosion coating in a stand-alone or dual-powder coating system, as well as under multi-layer insulation systems. When used in conjunction with Axalta’s Nap-Gard 7-2675 dual-layer system, the operating system increases to 356°F (180°C). The second layer ensures reduced water permeability and improved chemical resistance, the company says.
Because the coating is designed for higher-temperature operating systems, it enables oil to be extracted from greater depths and in more extreme conditions, resulting in higher performance and increased productivity. According to Axalta, it is presently being applied on a 50-km project in Mexico.
