Hello,

Does anyone have any experience with the urethane conformal coating from MG Chemicals (4223F)? It has notably faster cure times than our current product from Humiseal which made it interesting. Of course if there are other suggestions that have similar cure times to the 4223F (2hrs 100C) I would be happy to hear them!

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.

Not necessary wait long time coating fully cured, just cure enough for handling is ok.

The HumiSeal 1B31 is actually pretty fast drying e.g. 24h @ room temperature or 30min @ 76 °C Link
