HumiSeal® 1B15 is a single component, fast drying, easily repaired, acrylic conformal coating intended for use on printed circuit assemblies. HumiSeal® 1B15 coating is RoHS Directive 2002/95/EC compliant. Cleanliness of the substrate is of extreme importance for the successful application of a conformal coating. Surfaces must be free of moisture, dirt, wax, grease, flux residues and all other contaminants. Contamination under the coating could cause problems that may lead to assembly failures.
