Products that work once, but decisively

An anti-seize compound does not lubricate continuous motion — it separates two surfaces clamped together for months or years so they can be parted at the end. The mechanism is a suspension of solid particles in a carrier that evaporates or degrades: the oil disappears with heat, but the particles stay between the threads and prevent cold welding and seizure through corrosion. Two practical consequences follow that many people miss. First: the paste changes thread friction, and so the relation between tightening torque and preload — a bolt torqued to a figure calculated for dry threads ends up overloaded if it was assembled with paste. Second: an assembly paste for fitting (with MoS₂) and an anti-seize for later removal are not the same product, though they look alike.

Types and where each is used

Copper pastes are the classics, cheap and good to high temperature, but they are not used on stainless steel or light alloys, where copper promotes galvanic corrosion, nor near oxygen sensors. Aluminium pastes cover the same temperatures with less galvanic risk on steels. Metal-free ceramic pastes are the answer for stainless steel, non-ferrous alloys and electrochemically sensitive environments — brakes and exhausts included — and typically go to around 1,400 °C. Molybdenum disulphide pastes are for assembly and running-in, where they cut friction at first loading, not for later disassembly. Separately there are temporary protective coatings for transport and storage, which leave a waxy or dry film and are removed with solvent at commissioning.

Rules for application

A little in the right place beats a lot everywhere:

Correct the tightening torque. A pasted thread has lower friction, so the same torque produces significantly more preload than a dry one.
Do not use copper paste on stainless steel or aluminium — galvanic corrosion does exactly the opposite of what you wanted.
Apply to a clean thread. Over rust or degraded old paste, the new film has nothing to sit on.
Do not confuse an MoS₂ assembly paste with an anti-seize: the first is for first loading, the second for a disassembly two years out.
Check the product's real temperature limit, not the particles'. The carrier is gone long before the suspended solid is.
