Recommendation: Boron Nitride Lubricoat®, Boron Nitride Lubricoat-Blue®
Boron Nitride LUBRICOAT® offers the very best release / non-stick properties with good adherence and erosion/wear resistance when applied to most ceramic bodies. 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.
For first-time application instructions, please refer to product label and the PAINTING INSTRUCTION GUIDE. Note: do not apply over other types of coatings- bone ash, red mud, ...etc. In cases where bone ash or red-mud have been used, then our special Z-PRIMERCOAT should be applied before topcoating with BN LUBRICOAT®.
Coating Maintenance Guide
Need for coating maintenance is indicated by the sticking of the skin or skull. With LUBRICOAT Blue®, the need for coating maintenance is more easily indicated by the diminishing of the blue color. Also, LUBRICOAT Blue® makes spot touch-ups
much easier to observe and virtually eliminates over-application of the coating that can cause flaking defects and inclusions.
The lifetime achieved prior to the need for coating maintenance is dependent mainly upon the degree of wear or erosion. Occasional touch-up is performed as needed where needed as indicated by sticking of the skin or skull. Brush application is
permitted, but the surface must be below about 170 F to avoid defects.
Most commonly reported coating defect is flaking due to:
a. Inadequate surface cleaning prior to coating
b. Too thick of a coating
c. Heating to use temperature prior to thoroughly drying
d. Coating over another type of coating such as bone ash.
or blistering due to
a. Heating prior to thoroughly drying
b. Brushing onto a hot surface above about 170 F.
See Troubleshooting for specifics on what to do if these occur.
