Coppa Slip

Featured Replies

I don't need any convincing on the benefits of coppa slip, however, should it be used on Rotax motors?

Will the motor act as a sacrificial anode ?

Don't know about Rotax motors specifically but generally copper based compounds are used as 'anti-seize'. I think it's also good for high heat applications also eg. brake calipers. Grease is for lubrication.

I think so when used in ally. Best to stick with grease in engine bolts, although the ali based anti sieze in a mix probably fine.

The problems come in the presence of electrolites(water).

B40RT, where were you planning on using the copaslip exactly? If you are just lubing bolt threads, use the same Aluminium based anti-seize that you use on your spark- plug.

I have used coppaslip on rotax engines for 15 years with no problems, works really well on the various engine/case bolts that you don't want to sieze in place.

Thanks for the reply's, I have been using it for years, but a friend (chemistry graduate)sowed the seed of doubt. The only place I never lubricate is the plug thread, always seems to be enough oil kicking about to do the job.

I've noticed that the steel ignition case saver never rusts, even with no paint, so some sacrificial process is going on.

It must be all that polishing Ross. :hyper:

Same as last time - the Hydro at end of the month. Might you be twinshocking there?

You've committed your self twice now, no going back.

Just a comment:

The Rotax engine is made by magnesium alloy. Magnesium reacts with water. So it has to be painted and i.e. stainless bolts needs grease not to seese in the threads.

I would also use ordinary grease or one of the newer ceramic based anti-seese greases.

And in public too. This one might get washed more than twice a year.
