The popular Humiseal UV40 conformal coating is now available as a gel. The Uv40 gel by Humiseal was formulated specifically for some large scale LED (light emitting diode) applications including the huge LED displays that are seen in sporting stadiums where a light weight coating was needed. Humiseal UV40 gel is ideal when a light weight hermetically sealed housing is needed for electronic circuitry that will withstand extreme UV exposure, moisture ingress from rain and lightning strikes. The material has been used in the manufacturing of LED Displays carried on blimps and hot air balloons. The standard Humiseal UV40 conformal coating is applied with the UV40 gel around sensitive areas of the circuit board to increase the thickness of covering. Offering an application thickness up to 1mm, nearly 10 times the normal thickness of conformal coating.
The gel conformal coating materials by HumiSeal including the UV40 gel, provide more control and flexibility allowing materials to be deposited only where required and avoiding more sensitive area’s. As technology becomes increasingly more difficult with requirements to design smaller and more densely populated assemblies, the gel coatings offered by HumiSeal including UV40, the acrylic based 1B31 and the urethane based 1A33 are helping manufacturers meet reliability and performance targets for the life of the products. These products also allow customers to deploy damn and fill coating techniques around selected components by building a damn of gel product around a device and then filling with a standard conformal coating.
HumiSeal UV40 clear gel is a one part anti-sagging 100 percent solids dual cure acrylated polyurethane conformal coating possessing excellent chemical resistance, surface hardness, flexability and moisture resistance. The material is tack free after exposure to UV light and the secondary moisture cure mechanism will fully cure any exposed area’s of the coating within two to three days at ambient conditions, the secondary cure can be accelerated by baking.

Manufactured and available globally, HumiSeal’s range of gel products are the result of it’s ongoing work to continuously improve and develop sector-specific products that reflect it’s client’ needs in a real and competitive world.
