R391 / R392
BICON R391 compound is a non-hardening plastic weatherproof sealant which can be applied to protect electrical connections from moisture
and corrosive vapours. This compound has the consistency of a putty and also has good insulation properties, being rated at 1000V. It may
be moulded around terminals and connections or it can be used as a mechanical seal for any form of enclosure. The compound, whilst not
sticky, is soft enough to be readily moulded around intricate contours or pressed into fine cavities, and it has the ability both to resist the
dislodging effects of vibration and prevent moisture creepage along an interface. The compound does not harden on exposure to air or
sunlight, it does not shrink, crack or peel and although sunlight may cause a slight skin hardening, this does not affect the mass and can be
removed by working in the hand. Hence, it is ideal for use in maintenance purposes where cables may have to be removed or replaced at regular intervals.
The compound material does not liberate toxic fumes even if overheated and is harmless to the hands. It resists water permeation and is
unaffected by dilute acids and alkalis in liquid or vapour form, and many other chemicals. It has no deleterious effects on metals, plastic,
natural or synthetic rubber, PVC or other cable materials. However it is not resistant to oils, aromatics or aliphatic hydro carbons.

Applications
> The prevention of electrical leakage on circuits due to dampness and the protection of electrical contacts against corrosion.
> The sealing of irregular openings, cable entries, screw threads and covers of electrical equipment.
Make the right connection...
> It is useful as a filler for junction boxes and can also be used for many non electrical applications whenever a reliable non-hardening moisture
or water seal is required.
