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."

Try Humiseal 2A53. This is a very old 2-part epoxy coating that is still used by a number of companies as well as the military. Very hard to rework, transparent and may be what you are looking for

Not entirely clear on your question. We don't coat any of our hardware (assemblies are coated prior to hardware installation), so if coating needs to be reworked after this, then hardware removal is needed.

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.

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

Terry The SCC3 product is a vinyl modified silicone. It is less able to perform at low temps as it becomes brittle. It is not easy to repair because it is essentially silicone. It is not a qualified material to the MIL-I-46058 Spec. Are you sure yo

Hi Cecil, We using conformal coating in our manufacturing area, we did use to use Humiseal, others have been Bectron and Peters. We recentalt switched all lacquering to Peters, since it is lead free and it is a lot friendly than Humiseal. To answer

From various research I also found the HT500 series was/is being manufactured by Saint Gobain (part number M797). The product is still available through various distributors, though I imagine the quality issues will still be present. The quality issu
