Author Topic: Recommendations for Zinc Anti-Seize (Read 3163 times)

SKOL · « **on:** July 13, 2016, 08:51:53 AM »

I've been doing my research for anti-seize products to prevent galvanic corrosion. Many people argue for copper based, many argue for zinc based. I have thoroughly gone through and have decided to use a zinc based anti-seize when using stainless steel on aluminum.

Question: Anyone have any recommendations for a zinc based anti-seize that they have had a positive experience with?

I've found some online, but majority of them are in huge quantities. I don't really need a gallon bucket of anti-seize.

Thanks!

Permatex is what I grew up on. I have a jar from about 15 years ago that is still going strong.

Do you know if that is Zinc based? or what?

Any US auto parts store should have the basic silver colored anti-seize in single serving packages, small tubes, and medium sized plastic jars with brushes built into the lid.

It doesn't go bad so I recommend the container with the brush.

I use the Loctite brand zinc antiseize. NAPA used to carry it but stopped recently. I found it on amazon.

So does general "silver" dictate that it is zinc based then? couldn't it be another metal based if not labeled zinc?

I got the same Permatex stuff as above, and was recently wondering the same thing regarding ingredients.

"A highly refined blend of aluminum, copper and graphite lubricants"

Huh, so even though it's silver in color, it's actual part copper based and no zinc at all. Very deceiving. I'd hate to have to buy a zinc antiseize online, but all automat stores around me have basically that permatex silver or equivalent with nothing dictating that it's zinc based.

+1 I got the same jar.

The standard Permatex silver is a pretty common and well tested product. I would wonder if there is any particular benefit for pure zinc vs the blended materials used in the Permatex.

Zinc acts as an annode protecting the base metal. Not sure if it is applicable here, but that is why bolts are zinc plated. It protects the bolt and aluminum.

Disimlar metals cause a bad reaction that destroys metal. Mixing more metals together can't be a good thing imo. If the standard silver is what is used for aluminum aircraft that is what I would go with.

Your chemistry is quite correct but, speaking from a lifetime of experience, I have never had any stainless to alloy fasteners seize due to galvanic corrosion while using the easier to obtain copper based anti-seize compounds.

Interestingly I do have a tube of lead based anti-seize which seems to defy all logic since lead is barely higher in the electrochemical series than copper and unlikely to act as a sacrificial anode and is also much more toxic.

A while back a forum member here from Chicago offered a few 8oz. containers of 'Pro Honda' brand "Anti seize Compound" to us here and I purchased one from him.I'm sure it will last me for quite a while and i know it must be great for our Honda's as it's sold by Honda.He gave all of us a good deal over retail on it.

You are right. I'd like to go with Zinc based anti-seize for this particular scenario as I will be threading stainless steel bolts into cast aluminum threads. Zinc is at the very top of the galvanic scale (great ability to act as anode between two dissimilar metals), right behind magnesium. Which is why you'll find some really old timers dipping their bolts in milk of magnesia before threading them in. Crazy I know. Since magnesium has a high burn off temp, everything in MOM will boil off leaving a fine white powder of magnesium that doesn't start to burn off until upwards of 700 degrees F. I learned that from my neighbor who was an airplane mechanic in the Air Force working on B52's. Said that the Navy used it as well. Pretty neat

That's pretty neat, I've never seen that. I wonder what it's base metals are. I think the majority, if not all bolts, that are threaded into the engine are zinc plated steel. Threading zinc into aluminum is far safer in terms of galvanic corrosion than stainless steel , so I wonder if that anti-seize made by Honda what zinc based, or if they thought that was over-kill and went with aluminum or copper.

I looked on the back for any idea of ingredients but didn't see any.. it does say "Distributed by American Honda Motor Co. Torrance,CA." and then says "Made in USA" and then a number below it: H/C 7607617
This product is all silver in color..

This is the one

That's the smallest size that shows up, so it would be great if another member takes up the task of making smaller sizes for the forum.

I can't exactly remember but think it was around $12 shipped from the member here as he had bought some extra from a local dealer and felt that he wouldn't even use one bottle up in many years.
