HumiSeal® 1B51NSLU is a fast-drying, single-component synthetic rubber conformal coating with extremely low moisture vapor permeability. It contains methylcyclohexane solvent, making it more environmentally friendly than traditional solvents. The coating is highly flexible, applies with low stress on components, fluoresces under UV for inspection, and is easily repairable. It is RoHS-compliant (Directive 2002/95/EC).
