I believe Humiseal (and others) makes some water based coatings...www.humiseal.com Dymax has a no VOC UV cure if you have an adequate UV source.

You're correct, uV costs 1.7X solvent-based silicone. This high purchased material cost is counter balanced by uV requiring lower thickness due to higher solids and that 60 to 80% of a solvent coating is volitile and goes up the pipe between applicat

I have one brand new UV oven and 2 used ones. We used to cure Dymax conformal coating in this plant. We are selling those ovens.

Do a search in the archives on conformal coating and silicone conformal coat. A variety of companies make conformal coatings and the equipment to apply it. Coatings can be applied by dipping the board into the coating, brushing it on, or spraying i

Also coating costs depends on solids content vs final dry film thickness. Some newer UV coatings are 100% solids, so what you put down you get on the PCB after cure, use no solvents at all. So a cost to look at are qty of PCB per litre of material. T

If you are using a Humiseal. try UV-40 gel which is about 20Kcps. it will dam your material from capillary flow. It should be applied prior to coating of your low viscous material.

Humiseal has no-VOC coatings Acrylic and Urethane on offer, they too have non-VOC silicones and new UV curable also...!!!
