Maskant Materials

Maskant Powders

APV’s specialized maskant powders serve as barriers that prevent coatings from diffusing onto designated surfaces during high-temperature aluminizing processes. Whether the goal is to mask complex geometry, create clean transitions, or accommodate multi-step processes, APV’s maskant powders offer the flexibility and precision manufacturers rely on.

Benefits:

• Prevents coating intrusion on critical surfaces
• Works across high- and moderate-temperature processes
• Available in multiple powders for detailed or broad coverage
• Compatible with APV binders to form slurries
• Allows easy removal without residue
• Supports sustainable use with M-1 rejuvenation program
• Reduces scrap and rework

Maskant Binders

APV’s maskant binders bring structure and control to the masking process, combining with powders to form slurries that are easy to apply, dry uniformly, and perform reliably. Available in water-based and solvent-based options, these binders help manufacturers maintain process control, reduce variability, and ensure clean separation between coated and uncoated surfaces.

Benefits:

• Ensures uniform, reliable coverage
• Supports clean burn-off without residue
• Water- and solvent-based options for flexibility
• Enhances process control and repeatability
• Reduces variability and scrap

RTU Slurries

APV’s Ready-to-Use (RTU) slurries provide a pre-mixed, application-ready solution for masking complex parts, combining speed, consistency, and ease of use. Formulated with APV’s most widely used powders and binders, these slurries ensure uniform coverage, reliable adhesion, and predictable performance through high-temperature diffusion cycles. By eliminating on-site preparation, RTU slurries reduce operator variability, minimize waste, and support lean, efficient production.

Benefits:

• Pre-mixed for consistent performance
• Easy to apply with brushing or dipping
• Reliable coverage through high temperatures
• Reduces waste and rework
• Supports predictable, repeatable masking

Tapes, Preforms, and Putty

For challenging geometries such as those found on turbine platforms, airfoil roots, and manifold edges, APV offers flexible masking materials in the form of tapes, preformed sheets, and putty. Formulated with high-temperature powders and clean-burning binders, these materials protect critical surfaces during diffusion coating processes and remove cleanly without residue or ash.

Benefits:

• Conforms to complex shapes and surfaces
• Provides complete barrier protection
• Clean, residue-free removal
• Compatible with APV’s maskant products

Diffusion Coating Removal

APV’s ASC 2-N Stripper removes aluminide coatings from superalloy turbine blades after high-heat exposure.

Benefits:

• Complete coating removal
• Works at room temperature
• Precise, scalable application
• Preserves component integrity for reuse

Pack Diffusion Coating Powder

P-1 Powder is a pack aluminizing material used on nickel-based and cobalt superalloys. During thermal treatment, the powder diffuses aluminum and chromium into the part’s surface, forming a corrosion-resistant layer that protects the component in high-temperature environments.

Benefits:

• Consistent, high-quality pack coating
• Protects critical turbine components
• Aerospace-grade performance (PWA 252)
• Easy integration with custom slurry mixing and dispensing equipment

Specialized Application Equipment

APV offers industrial slurry mixing and dispensing equipment designed for precise application in automated systems or manual operations. This equipment reduces process variability and streamlines masking during high-volume production.

Benefits:

• Custom designed to your exact specifications
• Exceptional customer support before, during, and after installation
• Allows for more control during dispensing application
