HumiSeal® UV40 Gel is a single component, high solids, UV curable gel. A secondary moisture cure mechanism will cure unexposed areas within 7 days at ambient conditions. The gel fluoresces under UV light to allow inspection. HumiSeal® UV40 Gel is in full compliance with the RoHS directive 2015/863/EU.
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” assembly materials. Users should perform adequate testing to confirm compatibility between the conformal coating and their particular assembly materials, process conditions and cleanliness level.
