8462
Description
The 8462
Silicone Grease
is a translucent, water repelling (hydrophobic), non-melting, and lubricating
dielectric grease that provides superior corrosion and arcing resistance for connectors. It is widely
applicable because it is safe for most metals, rubbers, plastics, and elastomers. As well, it is usable in
many environments due to its high resistance and stability with respect to extreme cold, heat, humidity,
and other extreme exposure conditions like high voltages. Voltage arcing can be prevented due to its
excellent dielectric properties. Further, because it repels water, it provides excellent oxidation resistance
for contacts and relays.

Application Instructions
The performance of the 8462 Silicone Grease depends on surface preparation. Improperly prepared
contact surfaces can degrade the oxidation protection, dielectric properties, and lubrication characteristics
by trapping contaminants between the surface and the grease. The thickness and coverage should be
adjusted to meet your needs.
Prerequisites
•
•
Clean and dry the surface of the substrate to remove other oils and greases, as well as dust, water,
solvents, or any other contaminants.
(Optional) Wear gloves to avoid contaminating the surface and to avoid possible skin irritation.
Equipment
•
•
•
Lint free cloth (for cleaning contact and for wiping excess residue)
Spatula or stick application tools (sized appropriately for your application)
Isopropyl alcohol or other residue-free organic solvents (for cleaning)
N
OTE
:
Thoroughly clean oil-based cleaners (like WD-40) that are designed to leave a film on the metal
surface.
To apply the paste
1. Wipe the contact with a lint-free cloth.
2. Clean the contacts with isopropyl alcohol or other non-oil based cleaner.
3. Once dry, apply the paste with the application tool to the contact, ensuring adequate coverage and
desired thickness.
