WIRING
DIAGRAM MANUAL
5. Sealant Application
A. Before application
of sealant, check all
wires to make sure they
are properly attached
and in the correct
position.
B. After sealant
is applied,
joints should not
be flexed until sealant
is tack-free.
(1) At 77°F, sealant
will require 20 minutes
to be tack-free.
(2) Seventy-two
hours
is required
to cure sealant
thickness
of one-eighth
inch or
thicker.
C. Carefully
insert the nozzle into
the center of the wires.
Inject the sealant
keeping the nozzle slightly
below the surface of the sealant.
(1) The
injection shall be
done slowly to allow
the sealant to flow
between the wires as
it rises.
Entrapped air
may be released by
vibration or lightly
tapping the receptacle
on a firm surface.
(2) Do not damage connector contacts.
D.
When the nozzle cannot be inserted between
the wires because of spacing, insert the nozzle
to one
side of the
wires and as
near to the center
as possible
without forcing.
E. Application continues
until the mold
is filled.
(1) Backshells
should be filled
to a minimum height
of 0.25 inch above
the top of the longest
contact
or the highest shield termination.
(2)
Complete filling
of backshell is preferred.
F. Entrapment
of air within sealants must be avoided
in all cases. Air bubbles act as reservoirs
for
moisture buildup
which may lead
to short circuits.
