HumiSeal® 1C49 Silicone Conformal Coating

 

HumiSeal® 1C49 is a moisture curing, high build, VOC-free silicone conformal coating which provides excellent
moisture and environmental protection for printed circuit assemblies. HumiSeal® 1C49 is solvent free. The coating
demonstrates outstanding flexibility, fluoresces under UV light for ease of inspection and can be repaired. HumiSeal®
1C49 can be cured at room or at elevated temperatures. HumiSeal® 1C49 is MIL-I-46058C qualified, IPC-CC-830 and
RoHS Directive 2011/65/EU compliant, and recognized under UL File Number E105698.
