Hans,
Thanks for the info.  When I read the quote your provided, it seems to me
that it only speaks to protecting 100% metal surfaces (like Phil's bicycle
chains).  I would NOT take this to mean component leads or contact with
non-metal items like component bodies and circuit boards.  Is this how you
all read it?
Bev

Hi ya Charlie!

Alox 2028D is covered under MIL-C-81309 Type 3 Class 1  .  It's an avionic
grade "soft film" used to temporarily prevent corrosion when shipping
components (up to 1 month) . The Navy uses this stuff.  A website:
http://www.ciaci.com/aloxcorporation.htm
<http://www.ciaci.com/aloxcorporation.htm>   (although some of it is in
Brazilian I think).

I can see why you'd be concerned.

Hans
MIL-C-81309E

MILITARY SPECIFICATION

CORROSION PREVENTIVE COMPOUNDS, WATER DISPLACING,

ULTRA-THIN FILM

6.1 Intended use. The ultra-thin film, corrosion preventive compounds
covered by this specification are intended for use on any metal surface. It
can be used both for initial protection during shipment and storage and for
in-service treatment. It should not be used around liquid oxygen fittings.
The ability of these materials to prevent corrosion and to displace water
and their ease of application when packaged as class 2 (pressurized spray
cans) make them particularly suited for service use. These materials are
intended for indoor protection and short term protection outdoors where
surfaces can be recoated when required. These materials are not intended as
a substitute for other corrosion preventatives specified for protection of
surfaces for periods of more than one month.

I fully agree with Phil.  Surely they jest!  Naphtha and trimethylbenzene
have reasonably high boiling points but they are still flammable solvents
and should be treated with respect.  The latter has reported mutation
effects in lab animals (not specifically chemists).  "Hydrocarbon" is very
broad, but usually means a cut or two above naphtha on the distillation
column.  I would be concerned about higher boiling residues creeping into
switches, connectors; their effects on some of the cheaper plastics and
their really good ability to "suck" airborne dusts onto the circuit pack.
As far as the wax, which I presume is what they actually want to put on
their product, they might as well get my grandmother to melt some jam wax in
a double boiler and just pour it on their boards - just kidding!

hi,

surely you jest.  they may be confused.  i use it on the chain of my touring
bike and it works great there.

 One of my customers has
selected the Alox 2028D for use as a protective coating on their CCAs.
Can anyone share any info on the benefits of this product (if any) in
electronic packaging?
It is mainly Naptha, Trimethylbenzen, hydrocarbon and parrafin wax.
Described as a metalworking fluid additive.

I can envision a lot of problems with wash chemistry incompatibility,
insolubility and rinse water treatment etc.

Any info will be appreciated.

Thanks
