Conformal Coating Masking Solutions

Overview

SCH Technologies offers a comprehensive range of masking materials designed to be fully compatible with all liquid conformal coatings processes. Our purpose-built solutions ensure precise, clean, and efficient protection of critical PCB areas during conformal coating—without quality or time compromises.

SCH conformal coating masking materials are designed to be compatible with all conformal coatings and Parylene production processes.

Our Product Range

Custom Masking Boots

  • Reusable & cost-saving: Designed to replace masking tapes and dots during high-volume production, significantly reducing operator time and effort.
  • Tailored to your needs: Fully custom-made, matching your PCB components for an optimal seal and allowing repeat usage.

Masking Tapes

  • Clean performance: Our tapes are fully compatible with solvent-based acrylics, silicones, and polyurethane coatings. They peel off cleanly with no residue, and resist bleeding or de-wetting.
  • Options available:
  • Crepe Tape: Ideal for connectors and irregular shapes. Widths: 3–50 mm.
  • Silicone-Free Tape: Suited for flat areas like PCB edges or grounding planes. Widths: 3–12 mm.

Why SCH Masking Materials?

Works with All Common Coatings

Our masking materials are engineered to perform seamlessly with all major liquid conformal coating chemistries—including acrylics, polyurethanes, silicones, and UV-cure coatings. They apply and remove cleanly, with no residue left behind, ensuring reliable adhesion of coatings and primers.

Production Efficiency

Every masking solution is designed to reduce labour time and eliminate rework. Whether it’s reusable boots, clean-peel tapes, or pre-cut shapes, our products allow operators to mask and demask quickly and accurately. This efficiency translates into shorter cycle times, fewer defects, and consistent coverage across every batch.

Proven Reliability Through Testing

Unlike generic alternatives, SCH masking materials are validated daily in our own conformal coating service facilities. This real-world testing guarantees that each product can withstand coating, curing, and demasking without failure—while maintaining a clean surface free of contamination or residue.

Cost-Effective Performance

By combining durability, reusability, clean removal with no adhesive residue, and ease of use, our masking materials deliver long-term savings without sacrificing quality. Customers typically see reduced masking labour costs, lower scrap rates, and fewer material replacements—making SCH solutions a smart investment for both small-scale prototyping and high-volume production.
