HumiSeal UV-curable conformal coatings are high-performance acrylated polyurethane and urethane acrylate–based coatings designed for the fast and efficient protection of printed circuit boards. These coatings provide excellent protection against moisture, chemicals, corrosion, and mechanical stress, particularly in demanding environments such as automotive, aerospace, and defense industries.
Key Technical Features
- Dual-cure mechanism: The coating cures within seconds under UV light, enabling extremely fast production cycles. Shadowed areas under components, where UV light cannot reach, cure through a secondary moisture-cure mechanism within 2–3 days.
- Solvent-free: Most HumiSeal UV coatings do not contain volatile organic compounds (VOCs), making them more environmentally friendly and reducing ventilation requirements in manufacturing facilities.
- UV fluorescence: The coating contains a fluorescent tracer that glows under UV light, allowing automated optical inspection systems or manual quality control to easily verify coating coverage.
- High flexibility: The latest product generations are optimized to withstand severe thermal shock and temperature cycling without cracking.
