Teflon Grease vs Anti seize compound

There's a world of difference between lubrication greast (such as those used in bearings) and anti-seize compound.Say... That's a nice bike..

there is a subtle difference.
grease reduces the friction between two surfaces and allows them to pass over each other with less effort.
anti-seize stops two surfaces bonding together.0 -
You can use grease quite effectively as an anti-seize compound. It's not as good in high temperature applications, but there aren't any of those on a bike.
However, NEVER use anti-seize compound as a lubricant.- - - - - - - - - -

Don't try to get away with using grease as anti-seize where either Ti or carbon is involved; it's fine for steel or alu though.0

If you are putting Ti and a dissimilar metal such as Aluminium in contact, it is prone to galvanic corrosion, so an anti-seize compound is a good idea.Complicating matters since 19650

Grease is, always, a type of oil in a chemical or physical carrier that can be likened to acting like a sponge. Over time, the oil bleeds from the sponge and therefore lubricates the parts it seperates. It can contain solid lubricant particles dispersed in it, but doesn't always.
Anti-seize pastes is like grease, but contains much less oil, always has solid lubricating particles and has a much lower bleed rate and so isn't as good a lubricant.
So, if you tighten parts, use an anti-seize paste - eg nuts & bolts - if you want to remove them more easily when it comes to undoing them. Use grease if the part needs to be moved regularly and the fit isn't as tight - eg seat posts.
BOTH grease and anti-seize pastes can / do dry out over time. However, the anti-seize is designed to work when it dries which is why it contains solid lubricants. Greases generally cease to work when they dry out - there are of course, exceptions to this, but it's unlikely you'll use them on your bike.
There are specific examples where this differs, especially with carbon seatposts, but in general the above rule applies. Threaded part is subject to vibration, then using a light locking compound can be the ideal. Plenty exist that don't fully set dry and are vibration resistant - I tend to find this the best as it allows parts to be more easily removed than one that fully sets, but stops the part coming loose itself.0
