HumiSeal 1C49LVF is a silicone conformal coating that offers exceptional moisture and environmental protection for printed circuit assemblies. It is a low viscosity, VOC solvent-free coating that cures through moisture, and it boasts remarkable flexibility. For ease of inspection, the coating fluoresces under UV light and can be repaired. HumiSeal 1C49LVF can be cured either at room or elevated temperatures. Additionally, it is RoHS Directive 2011 65 EU compliant and recognized under UL File Number E105698.
