HumiSeal 1B31 is a fast drying, single component, acrylic conformal coating that provides excellent moisture and environmental protection for printed circuit assemblies. HumiSeal 1B31 is also produced as pre-blended products, at a range of viscosities, suitable for a variety of applications. HumiSeal 1B31, and its Pre-blends, demonstrate excellent flexibility, fluoresce under UV light for ease of inspection and are easily repairable. HumiSeal 1B31 coating is MIL-I-46058C qualified, IPC-CC-830 and RoHS Directive 2011/65/EU compliant. After complete cure, the properties of HumiSeal 1B31 Pre-Blends and HumiSeal 1B31 are comparable.
