Plane engine assembly

When it comes to high-diffusion coating and processing, protecting specific areas of alloy and superalloy parts is crucial. This is where maskant materials come in.

Maskant materials are commonly used in the aerospace, automotive, and electronics manufacturing industries to act as a barrier and protect surfaces from paint, plating or etching during processing.

APV Engineered Coatings offers superior maskant materials that are formulated to meet the specific requirements of various industries. Our innovative solutions ensure optimal performance and protection against damage and corrosion during processing.

Maskant Materials We Manufacture

At APV, we offer a diverse range of maskant materials, each designed to ensure optimal performance and protection. Whether its a high-temperature coating, low-temperature powder, moldable putty, flexible tape, or user-friendly slurry, APV can develop a masking system to meet your needs.


Preforms are custom-shaped maskants that fit precisely over the parts needing protection. They are particularly useful for complex geometries, ensuring that even the most intricate sections are adequately shielded.

Our preforms are crafted from materials that withstand high temperatures and aggressive chemical environments, providing reliable protection throughout the coating process.


Binders are essential in forming durable and resilient maskant layers. They help in adhering maskants to the substrate, ensuring they stay in place during processing.

Our binders boast impeccable formulation to resist breakdown under extreme conditions, maintaining their integrity and effectiveness throughout the coating cycle.

Maskant Strippers

After the coating process is complete, removing the maskant without damaging the underlying material is crucial.

APV designs strippers for the efficient and clean removal of maskants. They dissolve or peel off the maskant layer, leaving the protected areas intact and free from residue.

This ease of removal ensures that parts are ready for their next stage of production with minimal downtime.

Common Applications

Our maskant materials are designed for a wide range of applications. With our R&D-backed formulations, we ensure precise protection across various coating processes, including:

  • High-Temperature Diffusion Coatings: Our maskants withstand temperatures above 1500°F (815°C), providing reliable protection for parts exposed to extreme heat during diffusion coating.
  • Low-Temperature Diffusion Coatings: For processes below 1500°F (815°C), our maskants offer excellent shielding, ensuring that only the targeted areas are coated.
  • Pure CVD Coatings: Our maskant materials are ideal for chemical vapor deposition (CVD) processes, protecting critical surfaces while allowing precise coating application.
  • Aluminum Alloy Diffusion Coatings: Specifically formulated for aluminum alloys, our maskants ensure that only the necessary areas are treated, maintaining the integrity of the rest of the part.
  • Maskant Slurry Making: We provide high-quality materials for creating maskant slurries, ensuring consistency and performance in your masking applications.
  • Maskant Slurry Dilution: Our products include solutions for diluting maskant slurries to achieve the desired viscosity and application properties.
  • Maskant Stripping: After the coating process, our strippers efficiently remove the maskants, leaving the protected areas clean and intact, ready for further processing.

These applications demonstrate the versatility and reliability of our maskant materials in maintaining the precision and quality of high-value components across various industries.
