Aluminium-based anti-seize


Molyslip ALUMSLIP is a high-temperature, anti-seize compound formulated to protect fasteners from seizure induced by extremes of temperature, pressure and corrosion. The mineral oil base-fluid contains micronized particles of metal and non-metal fillers to provide excellent lubrication and protection to threads and components.

Molyslip ALUMSLIP is resistant to temperatures up to 1100°C and it effectively protects against chemical corrosion and atmospheric oxidation. Free of copper, lead, sulphides, fluorides and chlorides, ALUMSLIP is suitable for use on all studs, nuts, bolts and other threaded connections, including turbine casing studs, burner nozzles, boiler inspection points and furnace bolts. ALUMSLIP is specifically designed for where copper needs to be avoided (for example where concerns of galvanic corrosion exist).


• High temperature capability – up to 1100°C
• Ensures consistent friction between threads
• Protects against galling and seizure
• Protects against rust and corrosion
• Eases assembly of tight tolerance components


Molyslip ALUMSLIP should be used as supplied. Ensure surfaces to be treated are clean and dry – free from oil, grease or dirt contamination. Apply a thin even coating by rubbing onto the surface with a lint free cloth.

When a compound is applied to a threaded fastener that will be tightened to a specific torque setting, the torque setting will require adjustment to allow for the lubricating effect of the compound. Failure to do so can result in incorrect tension in the fastener.

Correct torque settings can be calculated using the tables and charts below and the standard thread equation:


T = Torque (N.m), D = Diameter (m), P = Clamping force (N), K = Nut factor
