THE MIRACLE OF BORON NITRIDE LUBRICOAT®


For Molten Aluminum & Magnesium (as well as other nonferrous metals), Their Alloys and Drosses

ACTS LIKE A TEFLON® COATING WITH MOLTEN ALUMINUM AND MAGNESIUM 

         Totally Non-Wetting to Molten Metals
Boron Nitride Lubricoat® is a paint that, when applied to metal, ceramic or graphite as a thin economical layer, will produce a surface to which molten aluminum, magnesium and their alloys and drosses will neither stick nor adhere.
        
FAMILY OF MAIN-USE, WATER-BASED BORON NITRIDE COATINGS
  From ZYP Coatings, Inc. – “World Leader in Boron Nitride Coatings”
[LISTED IN ORDER OF INCREASING TOUGHNESS/EROSION-RESISTANCE]

* BN Releasecoat®
            When exceptionally good release and good economy are required (such as for low-draft, high-drag areas of permanent molds), BN Releasecoat® is the solution.  Simply air-spray onto the problem areas of either a hot or cold mold that has been previously coated with a good quality mold coating – for excellent release and cosmetic surface finishes.  pH = Neutral, like tap-water.  Note that this coating is the SOFTEST boron nitride coating offered by ZYP Coatings
* BN Lubricoat®
            The best general-use paint that yields the maximum Teflon®-like non-stick, non-wetting behavior to molten metals.  Use this coating for most all applications.  Our standard/original Boron Nitride Lubricoat® yields a relatively soft, as-dried coating. pH = Acidic, like lemon juice.
* BN Lubricoat® Paste
            The PASTE version of our BN Lubricoat® is offered for when thick layers are
Desired … so that it can be applied by trowel, brush, or other tool as desired, still yielding a relatively soft, thick, as-dried coating. pH = Acidic, like lemon juice.
* BN Lubricoat® ZS
            When a coating is desired to be very-dilutable and still have good adherence and
Form a soft, as-dried coating, the BN Lubricoat® ZS is an alternative to our standard/original BN Lubricoat®. pH = Acidic, like lemon juice.
* BN Lubricoat® ZV
            This relatively-hard, highly-dilutable coating provides non-wetting with molten non-ferrous metals.  Additionally, unlike the prior LUBRICOAT® paints, pH = Basic/alkalin, like most housepaints … thus is ideal for use of plain-carbon steel or cast iron.
* BN Hardcoat®
            The most unique of our BN coatings, BN Hardcoat® is the only truly abrasion-resistant boron nitride coating available.  The BN Hardcoat® offers excellent wear and erosion resistance to molten metals as well as improved paintability by brush application, especially to metal surfaces.  BN Hardcoat®, however, yields somewhat reduced non-wetting, non-sticking behavior so its use should be reserved for high wear and erosive applications.

In the order listed from BN-Releasecoat to BN-Hardcoat, the characteristics of Non-Wetting and Lubricity are much higher for the Releasecoat and Lubricoat paints and decrease with the Hardcoat … whereas the Wear and Erosion-Resistance/Hardness/Toughness of the dried coating is much higher for the Hardcoat than for the other coatings.  Essentially, there is a tradeoff of increased hardness/toughness for decreased nonwetting performance.  Nonetheless, the BN Hardcoat performs quite well with molten nonferrous metals.
