Product Introduction
The HumiSeal® UV500 is a high-solids, dual-cure elastomeric acrylate coating designed for excellent flexibility, moisture resistance, and electrical insulation. This UV-curable coating cures tack-free under microwave or arc UV light with a secondary ambient cure mechanism, ensuring full curing in unexposed areas within 7 days. It offers enhanced thermal cycling performance and fluoresces under UV light for easy inspection.
HumiSeal® UV500 Features:
- Cures tack-free under microwave or arc UV light with secondary ambient curing.
- Provides high flexibility for improved thermal cycling performance.
- Superior moisture and chemical resistance.
- Fluoresces under UV light for easy inspection.
- IEC 60664-3, RoHS, REACH, UL, and China GB30981-2020 compliant.
- Compatible with all selective coating equipment.
HumiSeal® UV500 Applications:
- PCB & Electronics Protection: Moisture and insulation protection for PCBs.
- Selective Coating Processes: Suitable for spraying, brushing, and automated dispensing.
- Aerospace & Automotive Electronics: Performs well in high-temperature environments.
- Industrial Applications: Long-term resistance against chemicals and moisture.
- Touch-Up & Rework: Easy to apply for localized repairs.
