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 ceramic heaters supplied, have no thermostat, so they need to be manually turned off when the solution reaches 185 deg F. In an ambient room temp (approx 70 deg F) a 1.5 gal setup will take approx 20 minutes to cool to the minimum operating temperature of 165 deg F., so no further heating should be required. Careful attention to temperature during the last 10 minutes may show the need for a short burst of heat from the heaters. 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.
