Bostik Never Seez NSBT-8N, Pure Nickel Special, is a superior, high temperature anti-seize and extreme pressure lubricant recommended for use when applications prohibit the presence of copper, especially when resistance to corrosive acidic and caustic solutions is required. This high-quality grease contains flake particles of pure nickel, graphite and other additives in a special grease carrier found to enhance anti-seize performance. NSBT-8N contains no molybdenum disulfide, lead, or mercury except as trace elements and is recommended for use on stainless steel pipe fittings, flanges, steam generators, fasteners exposed to high temperatures, and fasteners in exhaust manifolds and boilers. The use of this high quality grease prevents seizure at high temperatures, as well as galling on stainless steel, titanium, magnesium and other hard metals. Never Seez Pure Nickel Special resists alkaline solutions, most chemical and acid vapors, road salt, steam, salt water and ionized water. NSBT-8N protects parts up to 2,400 degrees Fahrenheit and meets GE Aviation A50TF198 S2 Specification and GE EMPIS D6Y28C1 Specification.
