Here is a posting by P Kinner at Humiseal ... Typically, there are three main approaches to avoid coating wicking into press-fit connectors (and other keep out areas). Wicking is a phenomenon caused by a combination of low viscosity of conformal coa

There's some nice low-VOC uV coatings out there. We don�t use uV cured coatings, but try: * http://www.emersoncuming.com * http://www.dymax.com * http://www.mgchemicals.com * http://www.loctite.com * http://www.humiseal.com Be aware that uV co

We use one quite often. Our machine is a Uvitron Conveyor 40 as we are a large coating house and this allows us to process many boards. Dymax also maufactures and sells machines as well. Humiseal and Dymax both manufacture UV coatings. Emerson Cuming

Checked the archives with no luck. Anyone have a reliable test method of verifying acrylic conformal coat cure. Using Humiseal 1B31 mixed with approximately 30% solvent, spraying with a Nordson. Thanks in advance.

Humiseal says, "UV cure – These materials are also more difficult to repair as they are the most chemically resistant and mechanically tough of all conformal coatings. Removal is possible locally by using powder abrasion."

Once the HumiSeal conformal coating has been applied to the printed circuit board it is usually best to allow the material to reach a touch-dry stage, before heating the board to accelerate the cure schedule. This avoids potential problems such as bu

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.

Could someone point me in the direction of some good manufactures of batch style curing ovens? We have a new project requiring Humiseal 2A64 and we do not have an oven for the 3hrs @ 170F cure. Thanks in advance!

All URs require a long time to fully cure. And actually, most users do not reach full-cure before using the board. Even Humiseal 1A33 will be dry enough to handle after a very short time.
