HumiSeal 1B73 is a single component, fast drying, acrylic conformal coating intended for use on printed circuit assemblies. HumiSeal 1B73 is also produced as pre-blended products, at a range of viscosities, suitable for a variety of applications. HumiSeal 1B73, and its Pre-blends, demonstrate excellent flexibility and electrical properties, fluoresce under UV light for ease of inspection and are easily repairable. HumiSeal 1B73 coating is MIL-I-46058C qualified, IPC-CC-830 and RoHS Directive 2011/65/EU compliant, and recognized under UL File Number E105698. After complete cure, the properties of HumiSeal 1B73 Pre-blends and HumiSeal 1B73 are comparable.
