How do I use Contralube770?

Apply generously to the connector or contact surface you wish to protect.
In the case of multi pin connectors, squirt directly into the male and female
pins/holes of the connector you wish to safeguard. Administer to any spade,
bullet or any other type of push fit connector. Contralube is good for any
metal to metal contact – for instance an external antenna /RF connection. It
can be used to protect CCTV connections and is particularly useful for radio
controlled model enthusiasts.


How much Contralube770 should I Apply?

So long as your contact forces are sufficient (the amount of pressure that is
keeping the conductive contact areas together), you cannot over use
contralube770.


How does contralube770 work?

Contralube will weather proof/protect your connection and help stop rust,
vibration corrosion and the general build up of oxides. You can load up your
electrical and non-electrical connectors and connections safe in the knowledge
it will not interfere with the current flow or in the case of non-electrical connection,
it will not harm or weaken the signal that is going through the connection
eg radio waves or digital signals – amazing hey! A good description of how
contralube770 works is available in a downloadable PDF – Why contralube?


I am applying contralube770 to my multi-pin connector, will it cause ‘shorting’
between the pins?

Contralube can be termed ‘dielectric’ which translates to – A material which has
negligible electrical or thermal conductivity. Although contralube770 may be
physically bridging a gap between two separate pins/circuits it will not allow the
current to pass between the pins. Contralube770 has similar conductive
properties to air, so if you do not experience arcing/shorting between pins in
unlubricated connectors then the addition of contralube770 should not change
the performance/characteristics of the component.
Obviously, circuits utilising extreme currents/voltages are a different matter.  
We would recommend test/evaluation of contralube770 before using
operationally in all circumstances where extreme currents/voltages are present.


How should Contralube770 be stored?

Tubes of contralube770 should be stored indoors with the screw cap in place
and seated correctly. Storage should also be out of direct sunlight and not in
extremely hot and cold environments. Please try to keep the tube inside the
original carton along with the instruction/support information paper insert.


Where can I purchase contralube770?

Please take a look at our ‘Stockists’ page to find out where to purchase
contralube 770.


Contralube770 seems to turn blue, why is that?

The product contains a UV Tracer additive incorporated into it. Contralube770
will look clear in appearance although the UV tracer additive means that it
will turn a shade of blue when exposed to UV light/sunlight. Sometimes only a
small amount of contralube770 is used on small connectors. When dispensed
in small amounts it is hard to see and the UV Tracer makes the product visible
under UV light which assists with quality checks & inspections.


What about the functional life of contralube770?

Shelf life is the period following the lubricant’s manufacture during which it is
deemed suitable for use without re-testing its physical characteristics.
Functional life is determined by durability or accelerated life testing
of contralube770 in a component under expected operating conditions.
Contralube770 is designed for lifetime component lubrication, which often
exceeds 10 years in extreme operating conditions.


What is the shelf life of your contralube770?

The shelf life is four years from date of manufacture, provided that the oils and
greases are stored in their original, unopened container. The product should
be stored away from excessive heat.


How can I clean or remove contralube770 from my component?

Start by wiping off all the grease you can reach. Then wipe or brush all
surfaces with a solvent cleaner (isopropyl alcohol or similar).


Your product data sheet contains many lubricant properties. What are the
definitions for some of those properties?

Recommended Service Range (°C)
The operating temperatures at which the lubricant is expected to be fully
functional. Application and exposure duration my affect lubricant life.

Colour
The product is has a clear appearance although the UV tracer additive means
that it will turn a shade of blue when exposed to UV light/sunlight.

Thickener
The solid particulate that is dispersed within the base fluid to form the structure
of the grease, which is held together by surface tension and other physical forces.

Base Oil Type
The type of fluid used in the lubricant.

UV Tracer
A UV tracer additive is added so that a presence of the product can be viewed
when  used in small amounts. The application of a UV light will enable
contralube770 to be seen – it will show up as blue in colour. With the UV tracer
we use the best wavelength for the source of inspection light is 375nm.

Copper Deactivator
A copper deactivator is added to inhibit the catalytic effects of metal ions
especially copper, so they don’t form a gummy residue (or green slime) on the
surface. Since copper is often the under plating on connectors, the copper
deactivator is used for when the metal plating (eg gold) is scratched or worn
through; this then helps protect the under plating from being attacked.


Is contralube compatible with the materials in my component?

Compatibility issues are usually related to the base oil of the lubricant. The table
below gives a rough insight into the compatibility of contralube770 with some
of the more common plastics and elastomers. However, due to the variability
of plastics and elastomer, it is advisable to perform a compatibility test.
Submerge the material in the lubricant for more than two hours at 100°C.
A lubricant-free control sample of each material should also be subjected to the
same temperature at the same time. Material measurements – notably weight,
dimensions, shore hardness and tensile strength – should be made before and
after the test. Lubricant incompatibility can cause materials to swell, shrink,
harden, soften, become more or less brittle, change colour etc. Dimensional
changes of up to 5% are usually considered acceptable.

The compatibility table below gives a rough guide to the compatibility of
contralube770 with various plastics and elastomers. There are numerous
types & combinations hence that this is only a rough guide and a compatibility
test is recommended.
