HumiSeal 1B58LU is a synthetic rubber conformal coating that air dries and consists of a single component. Its unique chemistry provides it with an exceptional ability to resist moisture vapor permeability and improve thermal stability. The coating is highly flexible, puts low stress on components, can be easily inspected under UV light, and has effortless repairability. Additionally, HumiSeal 1B58LU contains methylcyclohexane, which makes it more environmentally friendly than traditional solvents. It is fully compliant with the RoHS Directive 2002 95 EC and IPC-CC-830.
