Humiseal UV40 UV Curable Conformal Coating

Humiseal UV40 is a single-component, high-solids, UV curable, acrylated polyurethane conformal coating designed to safeguard sensitive circuitry from moisture and chemicals. Formulated to deliver excellent surface hardness while maintaining flexibility, this Humiseal conformal coating provides long-term protection without compromising component integrity, ensuring reliable performance even under sustained environmental stress.

Curing efficiency is a key advantage of Humiseal UV40. The coating cures tack-free when exposed to microwave or arc UV light, enabling fast production throughput. In addition, this Humiseal conformal coating features a secondary ambient cure mechanism, ensuring that unexposed areas of the coating fully cure within two to three days.

Compatible with all selective coating equipment, Humiseal UV40 ensures seamless integration into automated manufacturing environments. For quality control and process assurance, the coating fluoresces under UV light, allowing easy inspection and verification of coating coverage.

Humiseal UV40 meets key international standards, including MIL-I-46058C, ISO 10993-5, IPC-CC-830 and Reach and RoHS Directive EU 2015/863, reinforcing its suitability for heavily regulated industries. As a trusted Humiseal conformal coating, it delivers outstanding protection against environmental stress while supporting efficient, high-quality production processes.
