HumiSeal UVA 300 conformal coating

Thursday, 18 July, 2019 | Supplied by: Onboard Solutions

HumiSeal’s UVA 300 LED cured conformal coating is designed to be cured through simple, single-wavelength LED UV light. The use of LED curing, versus traditional arc or microwave bulbs, is said to allow for simpler and more consistent curing, lower energy consumption, lower maintenance costs and no hazardous ozone or UVC exposure.

The product provides good protection and value for medium- and high-volume PCB manufacturing applications. Curing in seconds upon exposure to appropriate UV light, it allows for short cycle times and high production speeds. Its dual-cure chemistry eliminates the need for hazardous solvents and thinners, while the secondary moisture cure provides assurance of cure in hard-to-reach or shadow areas. It can be sprayed using traditional automated spray equipment and fluoresces under UV light to allow for easy inspection.

Properties include: an LED curing mechanism with secondary moisture cure; flexibility; thermal and mechanical shock resistance; 100% solids, with minimal environmental impact; ROHS 2011/65/EC compliance; adhesion to a wide range of commonly used solder resists; insulation resistance and moisture insulation resistance; and resistance to a wide range of solvents.
