Acrylic Conformal Coating is a professional acrylic-based protective coating designed for printed circuit boards (PCBs), electronic modules, power supplies, and control panels. It forms a thin, transparent film that protects against moisture, dust, corrosion, and electrical breakdowns, extending equipment service life and reducing the risk of failures.
Purpose and Functional Properties
- Protective and insulating coating for electronic components and printed circuit boards.
- Forms a transparent, flexible film that adheres tightly to the surface.
- Protects against moisture, condensation, dust, and corrosion.
- Reduces the risk of short circuits and dielectric breakdowns.
- The transparency of the coating allows visual inspection and soldering without removing the coating.

Limitations and Application Recommendations
- Clean and degrease the surface before application.
- Check compatibility with plastics and painted surfaces prior to use.
- Apply in a well-ventilated area.
- Extreme temperatures or constant moisture exposure may reduce coating effectiveness.
Choose This Product If…
- Reliable protection of electronics from moisture, dust, and corrosion is required.
- Transparency and visual inspection of components are important.
- Uniform coating of densely assembled components is needed.
- Reduction of repair and maintenance costs is a priority.
- Stable performance in demanding operating conditions is required.
Do Not Choose If…
- Materials are incompatible with acrylic coatings.
- Operating conditions involve extreme temperatures or continuous mechanical abrasion.
- Proper surface cleaning and degreasing are not possible.
- Complete coating removal is required during operation or repair.
- A specialized coating (silicone or polyurethane) is required for aggressive environments.
