Davef, thanks for inputs. I think your correct, we have since obtained some ionic analysis and sure enough there is relatively high chlorides on the bare pcbs. The toluene is controlled within dip tank / drying system, almost no exposure to workers.

Anyone aware of an acrylic conformal coating that is UV curable?

how does polyurethane used for wood floor coating differ from urethane conformal coatings sold for circuit boards? where can i get uv tracer to put in oil based urethane?

Alternatives are: * DSCC Columbus continues to maintain the QPL for MIL-I-46058C. [Engineering is unlikely to change.] * Use International Electrotechnical Commission Standard, IEC 61086 - Coatings for loaded printed wire boards (conformal coatings)

Many companies use IPC-CC-830B as a replacement for the deactivated MIL-I-46058 conformal coating standard.

We have PVA 350 benchtop dispensing equipement with humiseal 1A33 CC material. is there any moisture measurement process in conformal coating material?

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."

The good old days weren't all that bad. When I needed to have a specification callout for a conformal coating on an engineering drawing, I just used MIL-I-46058, type UR (for example), and the drawing checkers were quite happy. Since MIL-I-46058 ha
