HumiSeal UV40 is a single-component, acrylated polyurethane UV curable conformal coating. It is designed for rapid-cycle production environments where speed matters.
Key Features of HumiSeal UV40 UV Curable Conformal Coating
- Instant UV cure
- 2 to 3 day shadow cure
- Perfect for selective coating lines
Ready to Handle Immediately
This high-solids coating cures almost instantly under UV light. As a result, boards are tack-free and ready for handling straight away.
Complete Coverage, Even in Shadows
UV40 also has a secondary moisture-cure mechanism. This fully cures unexposed shadow areas under components within 2 to 3 days.
Hard, Flexible and Resistant
The coating is known for its excellent surface hardness, chemical resistance and flexibility. So it is ideal for protecting high-density assemblies from harsh conditions.
Easy Inspection
UV40 fluoresces under UV light for quick inspection. In addition, it is optimised for use with selective coating equipment.
Why Choose This UV Curable Conformal Coating?
With UL approval and robust physical properties, HumiSeal UV40 delivers both high throughput and high reliability. For example, it suits modern electronics lines where speed and performance are critical.
Because it cures in seconds, it can also free up space otherwise used for drying racks or ovens.
