Anti-seize Compounds
An anti-seize compound and a lubricant perform entirely different functions although many anti-seize products have lubricating properties, especially at higher temperatures. In environmentally adverse conditions such as high humidity and salinity, extreme pressure, acidic atmospheres or excessive temperatures, metals can fuse or weld together. The chief culprit is corrosion, particularly in marine surroundings. Molyslip anti-seize products are designed to provide an insulating layer between metals so that dismantling and routine maintenance are free from breakage of fused parts. This problem is especially onerous on threads and shackles. A single application of Copaslip (often misspelled as copperslip or coppaslip) or Alumslip will stop metal fusion for many years.

Theory of Molyslip Lubrication
In use, Molyslip products form a lubricating layer of Molybdenum Disulphide on metal surfaces in the following manner.
The Molybdenum Disulphide molecules arrange themselves into plates with a laminar structure in which each molybdenum atom is sandwiched between two sulphur atoms. The sulphur atoms are attracted to metal and therefore become plated or bonded on to each of the adjacent bearing surfaces. In between these two platings further layers of molecules form. The sulphur-to-metal bonding is very strong, but the sulphur-to-sulphur bonding between adjacent molecules is very weak.
Thus, there are two bearing surfaces, each protectively plated by a layer of Molybdenum Disulphide molecules with sliding or lubricating layers of molecules in between. In this way direct contact of metal-to-metal surfaces is prevented, friction is considerably reduced, with the consequent elimination of local heating, wear is inhibited and protection achieved even under extreme conditions of pressure and temperature.
The molecular thickness of Molybdenum Disulphide is such that there are approximately 40,000 lubricating or cleavage planes in an MoS2 film one thousandth of an inch thick!
The Molybdenum Disulphide plating is, in effect, a separating layer of immense strength, greater than the yield stress of most metals...and in addition it possesses the low coefficient of friction of ·03 to ·06 which gives more efficient lubrication combined with this greater protection.
