Product Description
The HumiSeal® UV500 UV Curable Conformal Coating is a high-solids, dual-cure elastomeric acrylate coating designed for flexibility, moisture resistance, and electrical insulation. This UV-curable coating cures tack-free under microwave or arc UV light, with a secondary cure mechanism ensuring full curing in unexposed areas within 7 days. It offers enhanced thermal cycling performance, excellent chemical resistance, and fluoresces under UV light for inspection, making it ideal for electronics and industrial applications.
Features of HumiSeal® UV500 UV Curable Conformal Coating:
- Curing tack-free with microwave or arc UV light.
- Providing secondary ambient curing for unexposed areas within 7 days.
- Offering high flexibility for improved thermal cycling performance.
- Ensuring strong moisture and chemical resistance for durability.
- Fluorescing under UV light for easy inspection and quality control.
- Being compatible with all selective coating equipment for precise application.
- Meeting IEC 60664-3, RoHS, REACH, UL, and China GB30981-2020 compliance standards.
Applications of HumiSeal® UV500 UV Curable Conformal Coating:
