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. |
