HumiSeal 1C53 is a silicone conformal coating that cures quickly with thermal heat. It is a single component and does not contain any VOCs. The coating has a low viscosity and long pot life, which makes it ideal for both dipping and spraying. HumiSeal 1C53 is flexible and contains an optical brightener, which allows for easy inspection under black light. This coating is MIL-I-46058C qualified, IPC-CC-830 compliant, RoHS Directive 2011 65 EU compliant, and recognized under UL File Number E105698.
