Overview
The document provides a comprehensive overview of APV Engineered Coatings' maskant materials, which are essential for protecting surfaces during high-temperature diffusion coating and chemical vapor deposition processes. With over 140 years of experience, APV offers a complete system of engineered solutions designed to ensure surface integrity in demanding industrial applications.
APV's maskant system includes a variety of products such as dry powders, binders, slurries, tapes, putties, and strippers, each tailored to meet specific process conditions and part geometries. The document emphasizes that masking is not a one-size-fits-all process; successful surface protection relies on the right combination of materials. The maskant powders serve as diffusion barriers, preventing coatings from intruding onto designated surfaces during high-temperature processes like aluminizing and chromizing.
The document details two categories of binders: water-based and solvent-based. Water-based binders, including B-100, B-200, and B-315, are favored for their low environmental impact and clean burn-off, making them suitable for various applications. B-100 is a general-purpose binder, while B-200 offers higher viscosity for thicker slurries, and B-315 is a low-VOC option for regulatory compliance. Solvent-based binders, such as B-4 and B-40, provide rapid drying and reliable adhesion, ideal for environments sensitive to water.
M-10 putty is highlighted as a versatile masking solution that can be easily applied to create physical barriers in complex geometries. It burns off cleanly during processing, leaving no residue, which simplifies post-process cleanup. Additionally, the ASC 2-N Stripper is introduced as an effective solution for removing aluminide coatings from superalloy turbine blades, working at room temperature to enhance safety and simplify processing.
The document concludes by positioning APV Engineered Coatings as a trusted partner for businesses seeking reliable and efficient masking solutions. The maskant materials are designed for user-friendliness and optimal performance, ensuring protection against damage or corrosion during processing. By choosing APV, manufacturers can benefit from a dedicated team committed to quality, efficiency, and success in their operations.
