HumiSeal - Transparent Coating, Conformal, Liter Can | 1B15

HumiSeal - Transparent Coating, Conformal, Liter Can | 1B15

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