NDB Stop-Off
Description

NDB Stop-Off coating is a “Do All” water-based coating for heat treating, being effective for all nitriding, carburizing, and carbonitriding atmospheres.  NDB provides a hard abrasion resistant barrier layer on all metals — proven effective for fluidized-bed processing, where abrasion resistance is mandatory.  NDB has no environmental/flammability problems like solvent-based stop-off coatings.

Key Attributes
  • 100% Effective for All Processes & Metals & Most All Case Thicknesses
  • Abrasion-Resistant, Hard Coating
  • Usable Even for Alloy Steels (8000 series, such as 8160)
  • Applied Like Housepaint by Brushing, Dipping, or Spraying
Ideal Use
  • Fluidized Bed Nitriding
  • Vacuum, Gas, & Pack Carburizing
  • Carbonitriding
  • Salt Bath Treatment
  • Scale & Decarburization Control

Zircwash
Description

Zircwash is a water-based paint that yields a low-to-medium-hardness coating that is 97% Zirconium Oxide [Unstabilized] and 3% Aluminum Oxide after heating to >600 C (>1112 F).   Easy-to-use coating that can be used to 2000 C (3632 F). Since the coatings CONTAINS NO SILICA, Zircwash is far superior to Zircon (Zirconium Silicate) coatings for melting/casting operations.

Key Attributes
  • Resistant to Many Molten Metals
  • Silica-Free
  • Very Low Thermal Conductivity
  • Applied Like House Paint
  • Safe, Water-Based, No VOC’s
Ideal Use
  • Crucible/Mold Coatings for High-Purity Molten Ferrous and Non-Ferrous Metals
  • Low-Thermal-Conductivity Layer
  • Anti-stick/Reaction-Barrier Layer

  • High Emissivity due to SiC
  • Usable on all Graphites / Carbons
  • Withstands Cyclic Use
  • Forms Sealed-Porosity-Coating That Stops Oxidation: Performs Best if Used > 700 C  (>1292 F) due to Pore-Sealing
  • Water-based, Ready-to-use, Like House Paint
Ideal Use
  • Oxidation Reduction and Prevention with Graphite and Carbons
  • Abrasion-Resistant Surface Sealant Layer for Graphite

MW-50 Paste
Description

MW-50 Paste is a water-based, fiber-strengthened paste based on Alpha Silicon Carbide (SiC). MW-50 can be brushed or troweled to form thick-stucco-like, abrasion-resistant shell that protects graphite and is also non-reactive to molten nonferrous metals.   MW-50 is also ideal for soft ceramic bodies and for repairing heavily-eroded graphite parts.

Key Attributes
  • Extends Lifetime & Reduces Maintenance
  • Provides a Hard, Abrasion-Resistant Layer
  • Repairs Graphite Parts to “Original”
  • Stops Further Oxidation, Wear, and Erosionof Graphite
  • Provides Tough “Shell” for Soft Ceramic Bodies such as Pulp-Molded Pieces
