One of the original creators and innovators in conformal coatings, HumiSeal® has led the way for over 50 years and today stands out as a uniquely experienced and dynamic company. HumiSeal is the only company in the market whose sole business is the development and supply of conformal coatings.
A conformal coating is a protective chemical coating or polymer film 25-75μm thick (50μm typical) that ‘conforms’ to the circuit board topology. Its purpose is to protect electronic circuits from harsh environments that may contain moisture and/or chemical contaminants. Some typical application examples include high-reliability defence, automotive and aerospace, where coatings are used to protect against various combinations of moisture, aggressive chemicals and vapours, salt sprays, large temperature variations, mechanical vibration, and even organic attack (e.g. fungus).
