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.

I would suggest lowering the viscosity even more. Humiseal even sells 1B31 pre-mixed specifically for spray machines and the highest they go is 65cps.

My company recently aquired an asymtek coating machine and I have been using Humiseal 1B31, an acrylic coating, in it to coat all the boards given to me. They have now come to me and asked if it is possible to run Humiseal 1A33, a urethane coating, t

I am looking into replacing another business division's Acrylic coating process with our Urethane coating process. Unfortunately, MIL-I-46068 doesn't differentiate AR/UR's performance, and the MFR data sheets don't match up at all (they each spec di

I'm currently working on bringing a manual coating process/workcenter online and my QA team is giving me some grief. For background, we're using Humiseal 1B31 thinned with thinner 521, mixed at 1:1 by volume. Spraying through a Binks HVLP with 10 P

We are in the process of revamping our conformal coating room. Presently, we have a C-740 Nordson Asymtek coating machine that sprays most of our boards with Dow Corning 2577. We are spending a lot of time masking boards and are thinking of upgrading
