Coatings for Aluminum and Nonferrous Metal Melting
ZYP Coatings pioneered the use of Boron Nitride coatings for this area-of-use. Here are some special areas and the most-often-used “candidate” coating.
Wagstaff Casting Tables
Use BN Lubricoat or BN Lubricoat-Blue.
If on a used table with Bone Ash residue, use Z-Primercoat as a sealant before applying Lubricoat
Wagstaff Transition Plates
Use BN TPC for a pink-colored smooth coating.
Degassers: Graphite Rotors & Stators
Use Coverguard for most areas, with MW-50 Paste at air-metal interface.
Filter Boxes/Bowls
Hand Ladles & Skimmers
Use BN Hardcoat.
Auto-Pour Ladles
Pins & Spouts
Use BN Lubricoat-Blue if brushing.
Use BN Lubricoat-ZS or BN Lubricoat-ZV (diluted 2-3 water: 1 coating) for dipping. The “ZV” is somewhat harder/more-durable.
Staulk Tubes
Metal: Use BN Hardcoat.
Ceramic: BN Hardcoat or MW-50 Paste.
Troughs, Launders, & Runners
Dross Presses
Use BN Lubricoat.
Permanent Molds
Use BN Releasecoat or BN Releasecoat-Blue applied as a topcoat over the typical thermal-insulating mold-coating. Ideal for low-draft/high-drag regions and to achieve “cosmetic” finishes for castings.
