Custom Conformal Coating Masking Boots
Reduce Costs and Improve Efficiency
At SCH Technologies, we specialise in designing and supplying custom, reusable conformal coating masking boots that replace traditional masking methods such as tape, dots and latex. Engineered for both liquid and Parylene conformal coating processes, our boots improve masking consistency, reduce labour time and generate significant cost savings.
We do not just supply them β we use these boots daily in our own coating services, proving their effectiveness in real-world production. Boot design, fit and expected reuse life will vary depending on whether the application is liquid conformal coating or Parylene masking, especially where gasket sealing is required.
For applications involving connector interfaces and protected contact areas, see our guide to protecting connector interfaces without conformal coating them.
Reusable masking boots help replace slower manual masking methods with a more repeatable, production-friendly process.
Why Choose Masking Boots?
Conventional masking techniques can be effective, but they are labour-intensive, error-prone and slow. SCHβs custom masking boots offer a smarter alternative β trusted not only by customers worldwide, but also used extensively in our own coating facilities:
- Faster application and removal β up to 5x quicker than tape
- Enhanced protection β helps reduce coating leaks and masking defects
- Durable and reusable β typically used 100+ times in liquid conformal coating applications
- Lower overall costs β reduce masking expenses by up to 80%
- Proven in practice β used every day in SCHβs coating services
Going deeper: reusable masking boots are not just faster to apply. They are used to improve sealing consistency, reduce operator variation and lower total masking cost in production.
Request a Quote
To provide a tailored quote, weβll need:
- Connector or component part code (to identify geometry)
- Estimated production volume
To speed things up, it also helps to include:
- A photo of the PCB (with masking areas marked if possible)
- Confirmation of coating type (e.g. acrylic, silicone, Parylene)
Reusable masking boots are designed for repeated use and can often exceed 100β200 cycles in liquid conformal coating applications when correctly specified, handled and cleaned. Service life will vary depending on coating type, geometry and process conditions.

Masking Boots are 4-5 times quicker than Tape
In a side-by-side trial, we compared traditional tape masking with SCH custom boots on a PCB with multiple masking points. The result was dramatically faster processing and major labour savings.

Case Study: Diamond MT (USA)
βWe initially tried SCHβs masking boots for the price savings, but quickly realised the boots lasted over 200% longer than expected. We switched immediately. Working with a supplier that truly understands coatings made all the difference.β β Sean Horn, Director, Diamond MT

Custom masking boots can reduce both masking labour and total cost when used in repeat production applications.
Conformal Coating Masking Training
Masking is one of the most labour-intensive and risk-prone stages of conformal coating. SCH Services delivers hands-on training covering masking boots, shapes, tapes and dots. Your operators learn best practices for speed, consistency and preventing leakage or defects.
This module can be delivered standalone or as part of a complete conformal coating training programme. Courses are tailored to your facility, aligned with IPC standards and focused on delivering practical, repeatable results.

FAQs β Custom Conformal Coating Masking Boots
What are conformal coating masking boots?
Conformal coating masking boots are precision-moulded, reusable silicone caps used to protect connectors and defined areas during coating. They replace tape, dots and liquid mask with a faster, cleaner and more repeatable masking method.
Can masking boots be used for both liquid and Parylene coatings?
Yes. Masking boots can be designed for both liquid conformal coating and Parylene processes. However, the way they are used differs. In liquid coating they act as masks, while in Parylene they often act as sealing gaskets, which places greater demands on fit and durability.
Learn more about masking boot applications and compatibility.
How many times can you reuse a masking boot?
Reusable masking boots are designed for repeated use and can often exceed 100β200 cycles in liquid conformal coating applications when correctly specified, handled and cleaned. Service life will vary depending on coating type, geometry and process conditions.
Do masking boots last as long in Parylene coating processes?
No. In Parylene applications, masking boots act as sealing gaskets rather than simple masks. This increases mechanical stress and sealing requirements, so reuse life is significantly lower and may be limited to a small number of cycles depending on the application.
How much time can you save compared to tape masking?
Masking boots are typically much faster to apply and remove than tape. In many applications, this can reduce masking time by several times and significantly lower labour input, especially in repeat production.
What do I need to request a quote?
At minimum, we require:
- Connector or component part code (to identify geometry)
- Estimated production volume
To improve speed and accuracy, it also helps to provide:
- A photo of the PCB with masking areas identified
- Confirmation of coating type (e.g. acrylic, silicone, Parylene)
Do masking boots prevent coating leaks and defects?
They significantly reduce the risk. A correctly specified boot provides a consistent mechanical seal, helping prevent coating ingress, edge bleed and contamination commonly seen with tape-based masking.
Can I request a sample?
Yes. Sample packs are available so you can evaluate masking performance, fit and handling in your own process before committing to production volumes.
Are masking boots proven in real production?
Yes. SCH masking boots are used globally and within our own conformal coating and Parylene coating services, ensuring they are tested and refined in real production environments.
