For the last few dozen years, I thought the slick silver stuff was the only kind of anti-seize made; that comes from living in a fourth-world area, more than a hundred miles from the nearest metropolis.

Lately, I have been seeing reference to a copper-colored anti-seize.

How many variations of anti-seize are there; and, what are their recommended, and avoided, uses??

Thanks.

 

The silver , you do not want to use in a situation where any would go down stream to any sensors [ especialy O2 in exhaust ] .
The copper is good all around , but it is espeicaly for higher temps .
There are others but they are rare , areo space ect .
If your trying to have one that will do most you'll ever need , get the copper .

 

copper, copper, copper....

 

And if you find yourself in doing some weird aerospace engineering, because of the metal content, either product make a decent "Second-Choice" heat-sink compound (coupling temperature sensors, TXV cap tubes and such).

 

Most of the silver stuff Ive seen is actually Nickel and it withstands much higher temps than the copper and far surpasses the copper stuff in most areas. In fact, some of the Nickel stuff is nuclear rated.

 

I thought the silver stuff was zinc based?

 

We use the pure nickel at work. http://www.neverseezproducts.com/bostik.htm
It is very good stuff. At the end of the day you will be covered in it.

 

Hi evilman... I figured a powerplant guy could find some NeverSieze brand "Nickel Special" somewhere...

I find the pure nickel stuff a little "chunkier/grittier" than the ordinary silver or copper stuff.. For ordinary stuff, I don't really like using the 100% Nickel stuff. Too gritty and stiff and after time, doesn't seem to lubricate threaded stuff as well as the ordinary silver stuff. (Aside from the high price)
BUT, this is definitely the stuff that you'll want to put on things that GLOW BRIGHTLY from the heat and that you'll want to take apart some day!

If you want to see what's in all those different anti-sieze flavors, go pull up the Mfr's MSDS for each product.. WOW! Silica??? Graphite Carbon? Zinc Oxide? Aluminum? Copper?(Copper even in the silver stuff!)

At a former employer, I had a most unfortunate co-worker that had developed a bad Nickel Allergy... Poor guy,... That pure nickel stuff in particular would deal him extreme grief for weeks after he merely touched an object that someone else had touched with it on their hands...
He would locate used cans of the stuff and throw them away so other people wouldn't use it on everyday stuff.

Actually, I have never seen silver stuff that didnt have the nickel in it. Interesting...

 

This is the stuff I was referring to.. Found it on KELLY15's link. http://www.neverseezproducts.com/purenickel.htm
It's used on our very high temp INCONEL reactor piping and stuff. Not real smooth, slippery stuff like the regular stuff is. No sulphur and DEFINITELY no Zinc! A little different than Nuclear Grade(I thought they were the same)

I learned something new about some of their other products on that website... They've got stainless steel(?)neverseez and heavy metal free neverseeze... Even Teflon neverseez! and Blue & Black Moly neverseez.

Im mostly familiar with the Loctite Nickel Antisieze ( http://tds.loctite.com/tds5/docs/NICASL-EN.pdf ) . Its good to 2400F and works very well.

Theres also Swagelok "Silver Goop" which works pretty well in high temp applications - but is about $60 a tube:

Our I&E guys and QC guys use the high purity goop from Swagelok. It is good on stainless fittings and wont contaminate our system.

On a side note dry neverseez with a little wd40 is good as new.

 

That poor guy needed 'anti-SNEEZE' instead of 'anti-sieze'!! Sorry, I couldn't resist...I have seasonal allergies and lots of chemical allergies too, can only imagine what that must have been like...fortunately not the Nickel allergy apparently, as I have always used what everyone refers to as the regular silver cheaper stuff, from water jacket bolts to exhaust manifold studs(meaning all temp ranges), never had any problems, but it's most informative to hear of the other compounds to tailor down to a specific use. Thanks everyone! :-)
