Masking Is Critical for Thermal Spray Area Control
In thermal spray coating, not every surface of a component should be coated. Many parts require precise coating areas, clean coating edges and reliable protection of non-coated surfaces.
During HVOF, plasma spray, arc spray and D-Gun coating, unprotected areas may be exposed to heat, overspray, particle impact and coating contamination. Poor masking can lead to unwanted coating buildup, difficult cleaning, edge defects, dimensional problems and rework.
Thermal spray masking materials are used to protect non-coated areas from overspray, heat, particle impact and coating contamination during HVOF, plasma spray, arc spray and D-Gun coating.
For coating shops and industrial users, proper masking is part of process control, not just a preparation step.
Masking Problems APT Helps Solve
Different workpieces and coating processes require different masking methods. APT helps customers consider overspray protection, edge control, geometry, repeatability and cleaning requirements before choosing masking materials.
Overspray Contamination
Protect non-coated surfaces from unwanted coating buildup and overspray contamination.
Edge Defects

Difficult Cleaning
Reduce post-spray cleaning time caused by coating particles attached to protected areas.
Complex Geometry
Support masking for holes, grooves, shoulders, threads, sealing surfaces and irregular part shapes.
Repeat Production
Improve masking repeatability for batch parts, repair parts and recurring coating jobs.
Rework and Cost
Reduce rework risk, unnecessary coating removal and avoidable production cost caused by poor masking.

Thermal Spray Masking Materials We Supply
APT supplies four main types of thermal spray masking solutions: masking tapes, masking putty, custom masking materials and masking fixtures.
This page provides an overview of APT's masking material categories. Detailed product pages are available for masking tape, masking putty, custom masking materials and masking fixtures.

Thermal Spray Masking Tape
Thermal spray masking tape is used to protect flat areas, edges and defined non-coated surfaces during coating production. It is commonly used for HVOF, plasma spray, arc spray and other thermal spray processes where overspray protection and clean masking boundaries are required.
Typical tape selection may depend on temperature exposure, particle impact, coating process, exposure time, adhesive residue requirement and edge quality. For thermal spray high temperature tape, APT considers HVOF overspray protection, plasma spray masking material needs and thermal spray edge protection requirements.
- Flat surface protection
- Coating edge control
- Overspray protection
- Temporary masking
- HVOF masking
- Plasma spray masking

Thermal Spray Masking Putty
Masking putty is useful for irregular areas, holes, grooves, threaded sections, curved surfaces and complex part geometries where tape alone may not provide enough protection or sealing.
- Hole masking
- Groove protection
- Thread protection
- Irregular edge masking
- Complex geometry masking
- Temporary sealing

Custom Thermal Spray Masking Materials
Some coating jobs require special masking shapes, pre-cut masking materials or process-specific masking protection. APT supports custom masking material selection based on workpiece geometry, coating area and spray process.
- Custom-cut masking
- Special coating areas
- Repeated masking patterns
- High-temperature protection
- Process-specific masking
- Customer drawing-based masking

Thermal Spray Masking Fixtures & Tooling
Reusable masking fixtures and tooling can improve masking efficiency, repeatability and process control for batch coating, repair work and complex components.
- Reusable masking fixtures
- Batch coating support
- Workpiece holding
- Edge shielding
- Repeat part masking
- Custom tooling
Compared with one-time masking materials, fixtures can help reduce preparation time and improve consistency when the same component type is coated repeatedly.
For repeat coating jobs, masking fixtures can reduce manual masking time, improve repeatability and make coating area control easier to standardize. APT supports thermal spray masking fixture design, reusable masking fixture planning and custom masking tooling for repeat production.
How to Choose Thermal Spray Masking Materials
Masking material selection depends on the coating process, spray temperature, coating area, workpiece geometry, surface tolerance and whether the masking is used for one-time work or repeated production.
Spray Process
HVOF, plasma spray, arc spray and D-Gun coating may require different masking strength, temperature resistance and edge protection methods.
Workpiece Geometry
Flat surfaces, shafts, holes, grooves, threads, shoulders and irregular areas may require different masking forms.
Coating Boundary
If clean coating edges are required, masking method and edge protection design become especially important.
Production Quantity
Single repair jobs may use tape or putty, while repeat production may benefit from custom masking fixtures.
Cleaning Requirement
Good masking can reduce coating removal and post-spray cleaning effort on protected surfaces.
Which Masking Option Fits Your Coating Job?
Different masking options are suitable for different coating areas, geometries and production routines.
Masking Tape

Typical Applications for Thermal Spray Masking
APT masking materials support different coating applications where non-coated surfaces, sealing areas, holes, edges and precision surfaces must be protected during spraying.
Shaft and Roller Coating
Protect shaft ends, bearing seats, sealing areas and non-coated sections during HVOF or plasma spray coating. APT supports masking for coated shafts where coating boundaries and bearing surfaces must be controlled.
Pump and Valve Components
Mask sealing surfaces, holes, threads and areas that must remain free from coating buildup. Masking for pump and valve components may require tape, putty or a custom thermal spray masking solution depending on geometry.
Ceramic Coating Applications
Support edge control and surface protection during alumina, chromium oxide or zirconia plasma spray coating.
Batch Coating Production
Use repeatable masking methods or fixtures to improve efficiency and consistency for recurring coating jobs.
