HumiSeal® Acrylic Gel is a fast drying, single component, thixotropic acrylic paste that provides excellent moisture and environmental protection for printed circuit assemblies. HumiSeal® Acrylic Gel has been designed for use with our acrylic conformal coatings. HumiSeal® Acrylic Gel can be used for sealing, damming and to provide an extra level of protection around component leads. HumiSeal® Acrylic Gel fluoresces under UV light for ease of inspection and is easily repaired. HumiSeal® Acrylic Gel is in full compliance with the RoHS Directive 2002/95/EC.

Application of HumiSeal® Acrylic Gel:
Cleanliness of the substrate is of extreme importance for the successful application of a Acrylic Gel. Surfaces must be free of moisture, dirt, wax, grease, and all other contaminants. Otherwise, ionic or organic residues on the substrate could be trapped under Acrylic Gel and cause problems with adhesion or electrical properties. The highest long term reliability for a coated printed circuit assembly will be when Acrylic Gel is applied over a clean, dry substrate.
The application of Acrylic Gel over no clean flux is a common practice. The user should perform adequate testing to confirm compatibility between Acrylic Gel and their particular assembly materials and process conditions.
