1. Product Overview

HumiSeal® 1B73 is a fast-drying, single-component acrylic conformal coating designed for printed circuit assemblies (PCBs). It offers excellent flexibility, electrical insulation, and UV fluorescence for inspection. The product complies with MIL-I-46058C, IPC-CC-830, UL (File E105698), and RoHS Directive 2011/65/EU. It is easily repairable and can be applied through dipping, spraying, or brushing.


2. Applications

  • Protection of printed circuit boards (PCBs) from moisture, contaminants, and electrical failure
  • Used in automotive, aerospace, industrial electronics, and consumer electronics
  • Compatible with low-residue “no clean” flux materials
  • Suitable for manual and automated application processes
