The HumiSeal 1C49LV Silicone Conformal Coating is a silicone coating that is ideal for circuit assemblies. It is low viscosity, VOC and solvent free, and cures with moisture. It provides flexibility and protection against moisture and environmental factors. Additionally, it fluoresces when exposed to UV light to assist with the inspection. The coating can be applied through spraying, brushing, or dipping methods.
