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.
Conformal coatings can be successfully applied to substrates that have been cleaned prior to coating and also to substrates assembled with low residue “no clean” materials. Users should perform adequate testing to confirm compatibility between the conformal coating and their particular assembly materials, process conditions and cleanliness level. Please contact a HumiSeal representative for additional information.
