Thanks for the info, I have 2 gallons of this do you think it would work I
use this for O rings and valve gasket installs very similar to what I am

HOW TO USE
DOW CORNING
4 Compound can be
applied
by hand, specially designed
automated
equipment, brushing or
wiping.
Certain designs of grease guns
may
seize up with silicone compounds;
test
prior to use.
A
thinner consistency can be achieved
by
dispersing in solvents such as
xylene,
mineral spirits and methyl
ethyl
ketone. DOW CORNING 4
Compound can then be applied by
brushing,
dipping or spraying.

DOW CORNING
4 Compound should
not
be applied to any surface which will
be
painted or finished. Such coatings
may
not adhere to the silicone-treated
surface.
If contaminated by a silicone
coating,
parts can be wiped or washed
with
solvent, washed with detergent, or
immersed
in an alcoholic potassium
hydroxide
solution and then rinsed in
clear
water before painting.
Dispensing
Separation
and compaction can occur
with
some high pressure dispensing
equipment.
This should be considered
when
designing dispensing systems for
use
with DOW CORNING 4
Compound.
For
information on appropriate
dispensing
equipment for your
application,
please contact
Dow Corning.
Solubility
DOW CORNING
4 Compound is
insoluble
in water, methanol, ethanol or
mineral
oil and is soluble in mineral
spirit
and methyl ethyl ketone. The
suitability
of a particular solvent should
be
based on testing prior to use.
Flammability
and toxicological
properties
should be important
considerations
in the choice of solvent.
Dimethyl
silicone compounds should
not
be applied to O rings or other
components
made of silicone rubber
because
they will destroy the silicone
rubber.
These
compounds will also slightly
swell
natural butyl rubbers.
Chemical
resistance
DOW CORNING
4 Compound is not
greatly
affected by mineral oils,
vegetable
oils or air. It is generally
resistant
to dilute acids and alkalines,
and
to most aqueous solutions. As each
application
may vary in chemical
composition,
pressure, flow velocity,
relubrication
requirements and
equipment
design, it is
recommended
that DOW CORNING 4
Compound be tested before adopting for
regular
use.
DOW CORNING
4 Compound is not
intended
to be used with liquid oxygen
and
should not be used in applications
requiring
LOX compatibility without
thorough
testing for the specific
application.

Subject: RE: [PSUBS-MAILIST] Hello Emile
I have visited this topic of compensating electric trolling
motors such as the minnkota motor many times on psubs over the past few
years. there is obviously a wealth of knowledge out there between you guys
but for a newby like myself drilling willy nilly into a motors outer shell with
little understanding of land marks and inner workings scares the hell out of
me, let alone fill a motor with a liquid and expect it to continue work .
i have been looking at the photos on the psub site taking great interest in the
motors and their "plumbing" but im sorry to say , i need idiot
proof assistance in his part of my construction. is there anyone of you guys
that has taken step by step photos and made written instructions on how to
pressure comp a motor? oil, air or other methods, what about loss of oil and
reservoir systems. what works best...etc. i have 5 minnkota motors to do,
all 30-45 HP
Many thanks in advance

Hello Emile,
I’ve been using WD-40 in the thrusters too. WD-40 is basically made up of a combination of baby oil, Vaseline, and a variety of “alkanes” (like nonane, decane, undecane and tridecane). The great thing about alkanes is that they cannot be ionized and therefore cannot bind with hydrogen, making them water repellant. One thing I like about WD is that it doesn’t produce as big of an “oil slick” on the water if some ever escapes. Oils slicks following your sub are not good!!! I think that the gas produced is cause by arcing of the brushes in compounds with slightly higher vapor pressure. The only real downside to WD-40 is that the Vaseline component can degrade the rubber seals over time (like any petroleum based lube) but it takes awhile.
Cheers!

Might be time to build a tank for testing. I like hydraulic oil better than silicone. It is actually slicker. We used it by the drum with the Pisces boats.

Subject: [PSUBS-MAILIST] compensatingHi, The compensation subject again…
We compensate the Eurosub engines with WD40. Work fine at depth but somehow the engines create gas so we have to pressure relief the compensation bottles every few dive hours. I try to get thin silicone oil to see if that works better.
For the time being I wonder how deep Minn kota’s etc. can operate NOT compensated (no oil and plugged).
Any thoughts/ expirience ??
