Incure Ultra-Illumina 3511B is a premium-grade, black UV-curable conformal coating formulated specifically for printed circuit board assembly (PCBA). This low-viscosity, fast-curing resin delivers a resilient, glossy, and opaque protective layer that safeguards electronics from moisture, dust, and harsh environmental conditions.
Features
- Superior Environmental Protection: The black, opaque finish forms a tough and glossy moisture barrier, ideal for both indoor and outdoor electronics exposed to humidity and contaminants.
- Dual-Cure Capability: While the coating rapidly cures under UV light, shaded areas beneath components are fully cured via a secondary heat-curing process.
- Eco-Friendly Composition: 100% solids, solvent-free formulation with no volatile organic compounds (VOCs), supporting sustainable manufacturing practices.
- Outstanding Mechanical Performance: Delivers tensile strength of up to 5,700 psi, Shore hardness of D75–D85, and excellent resistance to thermal stress.
- International Compliance: Certified to UL 746C, 94V-0 flame rating, RoHS, and Halogen-Free (HF) standards.
