Stabilant 22 connection enhancer: how does it work?
D...@cardio.hosp.wisc.edu
enhancer, work? The product is suppossed to be applied to your electrical
connectors before making a connection, where a thin film of the liquid then
acts to lubricate and presumably enhance the electrical connection. What
physical phenomena are being utilized by the liquid to decrease the electrical
resistance between the contacts? Is the liquid actually breaking down oxides
that form on the surface of the metal contacts? What is the composition of the
Stabilant 22 liquid? Are there alternative liquid products on the market which
claim to perform the same function? Jerry Pournelle, the Byte columnist,
mentions this "miracle" liquid so often that I wonder whether he's getting some
kickbacks from the manufacturer.

The way I understand it, Stabilant is used to prevent oxidation by forming a
protective layer over the conductors after the two slide together. I've
been trying out "Deoxit" and "PreserveIT" which are I suspect the same
thing. Supposedly the Deoxit removes oxides and then applies the thin
protective layer. I don't know why I bought the PreserveIT unless it's
protection is somehow better. You can get this stuff from Caig
laboratories for a pretty reasonable price. I don't really know how much
improvement it makes. I just applied it last week to some ATE connections that
had been giving me trouble and so far so good but it's too early to tell.

What I'm using..."DeoxIT" and "PreserveIT" are made by Caig Laboratories
which also makes "Cramolin" and several other cleaners and protectors. I
ordered mine from MCM Electronics @ 1-800-543-4330

Nah...he just needs to be a windbag. You've got to talk about *something*.
Sometimes Pournelle sounds like a broken record. I used to see him
mention "WORM (write once read only memory) drives" at least once every issue
of Byte for some reason.

I don't know of anything it can do for gold contacts, but tin-tin contacts
can suffer from fretting corrosion, a buildup of tin oxide due to the energy
produced by microscopic movements between the connector surfaces, mostly
as a result of temperature changes. Lubricants can prevent fretting
corrosion, though I'm not sure I recall seeing any data on how they work,
seems to be partly excluding oxygen and reducing the frictional
energy between the contact surfaces. Can anyone shed any light on this?

As I understand it Stabilant 22a is much more than a lubricant,
and is a polymer that conducts under the influence of a magnetic field.
(i.e. does not short across contacts if used in over generous quantities).
I have found that it works where normal contact enhancers fail,
and is non-corrosive (some contact enhnacers have deoxidants that seem to
promote corrosion at a later date.).
It is expensive, but a small tube goes a long, long way; and I have had
very good experiances with it.

Does anyone know what the Trade Name in Japan for this stuff is?
I am sure that the Japanese screwed up the name of the product, they always
do.
Will....
