About HumiSeal
About HumiSealConformal Coatings
HumiSeal has led conformal coating technology for more than 60 years, standing among the original creators and innovators in a category built specifically to protect electronic devices from humidity, moisture, and environmental stress. The HumiSeal brand is manufactured by Chase Electronic Coatings, an operating division of Chase Corporation, which has continued to expand the product line's global reach.
A significant chapter in HumiSeal's international growth came with the 1980 formation of Concoat Ltd as a HumiSeal distributor, which later became a licensed manufacturer and developer of conformal coatings in its own right before being sold to Chase Corporation in 2005. The HumiSeal team specializes in the research, development, and manufacture of conformal coatings, thermal management materials, potting and encapsulating compounds, and specialty adhesives used to protect electronic and industrial devices against moisture, surface contaminants, mechanical and thermal stress, and UV and chemical exposure.
HumiSeal's conformal coating range includes acrylic, urethane, and silicone chemistries available in solvent-based, water-based, and UV-curable formats, each rigorously tested to recognized industry standards including MIL-I-46058C and UL 746E. ChatMRO helps electronics manufacturers source HumiSeal coatings by matching exact chemistry, cure method, and dielectric requirement against verified stock for aerospace, defense, and high-reliability electronics applications.
