Concoat develops unique water-based Humiseal coating

Keywords Concoat, Conformal coating

Concoat has engineered a revolutionary water-based conformal coating addition to its industry-leading Humiseal range that can protect electronics assemblies at temperature extremes far beyond the capabilities of existing resin-based alternatives. "1H20 is currently undergoing qualification testing between–65°C and +185°C," says Concoat's Technical Director, David Greenman. "Because the top end figure is at least 508C higher than conventional resin materials, this product will be especially relevant to the automotive industry where upper performance limits are ideally rated at 180°C for engine bay electronics".

"As water-based coatings, the 1 H20 series are also extremely environment-friendly products that are intended to meet with the drive in Europe to reduce VOCs."

The performance characteristics of Humiseal 1H20 stem from a totally new water-based chemical formulation that was engineered by Concoat and took over a year of dedicated R&D effort to produce.

"Not only are the performance attributes of 1H20 in temperature extremes superior to most other coatings, it also delivers a general performance level that far exceeds that of other water-based coating materials", continues Concoat's Research Chemist Phil Kinner, who joined the company after winning the top student project award in last year's Shell STEP programme for his work placement that contributed to the development of water based materials.

"1H20 is both safe and easy-to-use, it has a superior 8KV breakdown voltage that is higher than conventional resin, it is extremely flexible and offers excellent chemical and MAR-resistance, and is repairable. And by being non-hazardous and low odour, it greatly reduces the demands on fume extraction equipment."
