WAGSTAFF CASTING TABLES |
Boron Nitride Lubricoat® and BN Lubricoat-Blue®
are excellent for casting tables used in Wagstaff Billet Casters.
BN Lubricoat-Blue® is an easy-to-see blue color that
provides Teflon®-like release that is so good that even mispours
can easily be lifted out. They extend refractory life, stops
refractory deterioration due to corundum growth and avoids
inclusions that are a problem with other coatings such as bone
ash.

Z-Primercoat
This water-based, clear light-syrup-appearing liquid is designed for sealing the surfaces of porous ceramics and boards. It is desirable to clean off as much residual dust and contamination as possible. Still, Z-PRIMERCOAT can be coated over these materials to some extent. By merely painting or swabbing this material onto the ceramic, the surfaces become much more amenable to topcoating with boron nitride coatings such as Boron Nitride Lubricoat® and Boron Nitride Lubricoat-Blue® which react with materials like Bone Ash and red mud as well as some binders used in ceramic boards and the like . Without Z-PRIMERCOAT, the acidic Boron Nitride coatings can lead to some degree of spallation and/or mud-cracking that occurs either on drying or during high-temperature use. By using the Z-PRIMERCOAT, these problems can be prevented or reduced considerably.

CASTER TIPS |
Changes in insulation characteristics of the caster tip can
be caused by reactions between the binders of the ceramics tips and the molten
metal. This reaction will form a black layer inside the tip. This layer
decreases the thermal conductivity of the tip which adversely affects the
properties of the sheet so that the properties of the sheet are not constant for
the duration of the cast.
Boron Nitride Lubricoat® creates a protective non-reactive
barrier inside the caster tip. This barrier will eliminate these reactions
between the binders of the caster tip and molten metal so that the build up of
black layer inside the tip is eliminated. This will ensure that the
insulation characteristics of the tip are kept constant and the properties of
the cast sheet do not change.

DEGASSERS / GRAPHITE - ROTORS & STATORS |
Typically, Coverguard is applied over the entire graphite
surface for both the rotor and stator.

At the air-metal interface, MW-50 Paste (a fiber reinforced
paste) is built-up as a thick (about 1/4 inch) layer so as to
provide longer-life protection. MW-50 Paste can also be used to repair
worn shafts and to repair cracks and breaks. In one field
test, a shaft that was reduced in diameter by over 50% was
repaired to original dimensions and placed back into service.
The life of the repaired shaft was 2 1/2 times longer than that
normally observed for a new shaft.

DROSS PRESSES |
Boron Nitride Lubricoat® is an
excellent choice to prevent dross/skull from welding to the press
head. BN Lubricoat® provides protection and release for
40 to 50 cycles before re-coating is needed. In field trials,
BN Lubricoat® provided longer lifetime than any other coating
available

FILTER BOXES |
Boron Nitride Lubricoat® provides extremely easy
removal of a filter. This is due to the Teflon®-like release
properties of the coating. Instead of jerking and prying a filter out
of the box, the filter simply lifts out with little or no effort. Removal of the filter is this easy because the Boron Nitride Lubricoat® creates a layer of protection on the ceramic on which the aluminum and
filtered impurities simply won't stick.

HAND LADLES & SKIMMERS |
Boron Nitride Hardcoat® is the
product of first choice because of the high wear and abuse experienced
with this use. In addition to providing Teflon®-like release,
BN HARDCOAT®saves money since the coating
lasts about 7 times longer than the traditional coatings. Also, BN
HARDCOAT®is less expensive to use since coverage is much better.
About 1 gallon of BN HARDCOAT®replaces 20 gallons of
traditional paints. Also, because of the Teflon®-like release, dross
build-up is eliminated allowing for cleaner pours and the elimination
of mis-pours.

AUTO-POUR LADLES |
BN Lubricoat® or BN Lubricoat-Blue®
is recommended for this use because of its
superior Teflon®-like release properties. For auto-pour ladles,
this is the property of most importance. If aluminum skin builds
up as it does with traditional coatings, mis-pours can occur
because the shot size is reduced and/or the lip area is
obstructed.

PERMANENT MOLDS |
BN RELEASECOAT® or
easy-to-use BN RELEASECOAT-BLUE® provides unsurpassed Teflon7-like
mold release and mirror-like surface finish for permanent mold/low

BN RELEASECOAT® is applied over the
usual insulating mold coating and touched-up as needed in
service. BN RELEASECOAT® is ideal for low draft / high drag
regions of molds.

BN LUBRICOAT BLUE® (for Brushing)
BN LUBRICOAT®-ZS (for Dipping)
BN LUBRICOAT®-ZV (for Dipping)
For application using full strength (non-diluted) product applied
by brush or spray, the BN LUBRICOAT BLUE® is the best product.
Users especially like the blue color for ease in maintenance and
application.
For dipping application, use the BN LUBRICOAT®-ZS or BN LUBRICOAT®-ZV
diluted 4 or 5 parts water to 1 part paint. Agitate the mix in the
dipping tank to keep suspended.
For denser ceramics, both the ZS and ZV formulations work the
same. For porous ceramics the ZV formulation provides a harder,
more durable coating.

STAULK TUBES |
METAL STAULK
TUBES
BN Hardcoat®
offers superior wear/erosion resistance and adherence and easy
brush application to metal surfaces. BN Hardcoat®
protects the metal from burn-through due to metal attack and
allows easy removal of any adhering dross or skin. BN
Hardcoat for this use is very similar to its use with metal
troughs. Staulk
tube life is typically doubled leading to improved cost savings.
One firm saves over $400,000.00 per year by using BN
Hardcoat® to protect their staulk tubes.
CERAMIC STAULK TUBES
The primary problem to be solved by a
coating is to seal porosity that exists in ceramic staulk tubes.
Both of the products below have been demonstrated to work and the
coating selection is primarily driven by shop practices.
BN Hardcoat® is applied to both
the inside and outside of staulk tubes using either standard
brushing or dipping methods. If brushed, a roller or sponge
attached to a pole facilitates coating the inside surfaces. For
dipping, a PVC pipe capped at one end and filled with BN
Hardcoat® is one method used. Alternately, for
coating the inside of a tube, the tube itself can be taped off on
one end, and the coating poured into it and then poured out. If dipped, as much of the
excess paint needs to be removed since thick coatings are much
more likely to flake in service.
MW-50 Paste should only be
applied by brushing to the outside of the staulk tubes. Unlike
BN Hardcoat®, a thick (about 10 mils or more) is recommended
(fiber reinforcement used in MW-50 Paste permits thick
coatings). Of course, these thick coatings require longer time to
thoroughly dry; and if not thoroughly dry before use, the coating
will flake during use. Many users employ a drying oven.
Performance data suggests that the MW-50
Paste is best at sealing the porosity but, of course, skin and
dross will adhere -- unlike what would be observed with the BN
Hardcoat®.
Some users will top the MW-50 with BN
Lubricoat® . Why BN Lubricoat® and not BN
Hardcoat®? MW-50 uses an acidic binder -- same as BN
Lubricoat®. BN Hardcoat® uses a basic binder. If these
two binders are not the same, an acid-base reaction can occur
causing coating flaking.

Boron
Nitride LUBRICOAT® offers the very best release / non-stick
properties with good adherence and erosion/wear resistance when
applied to most ceramic bodies. BN LUBRICOAT® (standard white
or easy-to-use blue) extends refractory life 2 to 5 times thereby reducing the number of costly
rebuilds and downtime, stops damaging corundum growth, improves
metal flow, virtually eliminates use of lime, bone ash,
red clay mud, ...etc. therefore
reducing the risk of inclusions and of course, makes the
removal of the skin or skull very
easy without damaging the ceramic. BN LUBRICOAT® eliminates the
need for trough maintenance after every drop thereby saving time
and money.
