BN EN is an extremely slick, abrasion resistant, low-friction,
high lubricity coating.
Ideal for all types of guns, engine pistons,
fry pans, in fact anywhere where dry lubrication and
non-stick is an issue. We see interesting potential
in lining parts of Paintball Guns to prevent wear of
the soft aluminum.
The coating can be applied in 20 minutes,
to aluminum, steel, nickel, copper, brass and bronze.
Other metals can be treated as long as a nickel plate
is previously applied.
Where corrosion may present a problem
(such as on steel) the part should be previously plated
with at least 0.0002” of Electroless Nickel plate.
Generally gun components can be plated directly without
a base primer of nickel.
The coating is applied at 0.0002”
in 20 minutes. The system runs exactly the same as Caswell
Electroless Nickel, except that it has a special filter
pump, which agitates the Boron Nitride powder, keeping
it in suspension. . The pump has a plastic tube, which
should be secured to the pump body aiming the jet towards
the bottom center of the tank. As the nickel is plated
onto the surface, the minute particles of Boron Nitride
are bonded all over the surface of the nickel, giving
the part unique properties.
The solution is placed in the glass lined tank, and heated on a hot plate or stove top to 185 deg F. A thermometer is included. Operating at above 185 deg F will
cause the bath to plate out too rapidly and it will
start to deteriorate.
The system requires constant agitation, so a pumping system is required. The pump must be able to withstand 185 deg F. If you do not have such a pump, we sell an optional unit. You will also need fittings and tubing to connect the pump to the plating tank - available in any hardware store.

After plating, the pump should be left
to run until the solution temperature has reached ambient
again. At this point the plating reaction ceases. Failure
to do this will result in the BN particles dropping
to the bottom of the tank, where they will be plated
into a solid mass. This will ruin both the particles
and the solution. The bath must be maintained at between
70-105% nickel content by replenishing with Part A &
Part C.
The BN Particles are slowly depleted
from the solution. However, there will always be about
50% of these left over after 5 nickel replenishments.
To recover the BN particles, the solution may left idle
for 3-5 days and they will settle on the bottom. The
spent solution may be carefully siphoned or decanted
off and the BN particles may be re-used if they are
free from nickel. For high output users, this may be
an economical saving, as BN particles are a major expense
of the kit. There is a special retrieval procedure involving
nitric acid, which will remove the nickel. This information
is available on request.
The BN EN finish has a satin look to
it.
