Axalta Coating Systems has launched its latest generation Nap-Gard product, which can withstand continuous operating temperatures of 155°C (311°F). Nap-Gard High Tg 7-2555 is a thermosetting epoxy powder designed for use as a corrosion barrier coating for underground and sub-sea pipelines that operate in high temperature service. It can be used as a corrosion coating in a stand-alone or dual-powder coating system or as a corrosion coating under multi-layer insulation systems. When used in conjunction with Axalta's most recent dual layer system Nap-Gard 7-2675, the operating system increases to 180°C (356°F). The second layer ensures reduced water permeability and improved chemical resistance.
Nap-Gard 7-2555 is currently approved by operating companies in Mexico, Colombia and Venezuela. It is presently being applied on a 50km project in Mexico. Nap-Gard 7-2555 builds on the previous generation Nap-Gard 8-2535 which was designed for operating temperatures up to 135°C (275°F).
