Loctite Nickel Anti-Seize 8 oz Can — Copper-Free High-Temp Anti-Seize, Corrosion Resistant

Loctite 77124 Nickel Anti-Seize is a heavy-duty, copper-free lubricant formulated to prevent seizing, galling and corrosion on metal parts exposed to extreme heat and harsh chemicals.

Designed for industrial and maintenance use, this anti-seize compound blends tenacious metals, oils and graphite to form a durable film that withstands temperatures from -54 °C to 1,315 °C. It’s engineered to stay in place on slow-moving surfaces and resist attack from acids, ammonia, acetylene and vinyl monomer, making it a versatile choice for everything from threaded pipe joints to die lubrication.

How does this product stop bolts and fittings from seizing in hot environments?

Loctite 77124 creates a high-temperature barrier between mating metal surfaces so thermal expansion and corrosive deposits don’t lock parts together. Its metal-filled formulation maintains separation even under extreme pressure and heat, allowing parts to be disassembled after long service life.

• Nickel-based metallic carrier resists high temperatures and chemical attack.
• Graphite and oils provide long-lasting lubricity under pressure.
• Maintains effectiveness at up to 1,315 °C for many industrial applications.

Where should I use Loctite 77124 in a plant or workshop?

This anti-seize is suitable for heavy-duty, high-temperature and corrosive applications such as bolted flanges, conveyor chains and press-fit assemblies. It is commonly applied to fasteners, die surfaces and gaskets where exposure to heat or aggressive chemicals is expected.

• Pipe threads and pump housings in chemical plants.
• Drop forge dies, hammers and catalyst bed supports.
• Conveyor chain pins and high-temperature gasket coatings.

What makes this Loctite anti-seize different from ordinary lubricants?

Unlike standard oils or greases, Loctite 77124 includes heavy-duty metallic additives that do not burn off or get displaced by slow-moving parts. It is copper-free, reducing the risk of galvanic corrosion in sensitive systems while providing a robust film that resists acids and other aggressive chemicals.

• Copper-free formula to minimize galvanic concerns.
• Resists acids, ammonia and other industrial chemicals.
• Clings to surfaces under slow movement and heavy pressure.

How should I apply and store this anti-seize for best performance?

Apply a thin, even coating to cleaned threads, flanges or contact surfaces; avoid over-application to prevent contamination of surrounding components. Store the can in a cool, dry place and keep the lid tight to preserve consistency and shelf life.

• Clean mating surfaces of rust, oil and debris before applying.
• Use sparingly—thin film delivers protection without mess.
• Store upright at moderate temperatures, away from open flames.

Who is this for? Maintenance technicians, plant engineers and metalworkers who need a resilient, high-temperature anti-seize for corrosive or severe-service environments will benefit from Loctite 77124. It’s especially useful where threaded or press-fit parts must be removable after prolonged exposure to heat or chemicals—ideal for heavy industry, forging shops, chemical processing and equipment maintenance teams seeking dependable protection and easier disassembly.
