Does anyone know of a good gasketing material that will hold up over time in a select coat fixture?

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

We have PVA 354Bench top conformal coating machine. We are going to procure the Humiseal 1B31 material. Is this material is suitable for this model of machine? Is there any special pecautions to be taken while programming? What are the main problemsd

Update on 1B73 bubbles, Changed over to a mixture of Humiseal 73 thinner with coating (25 sec on Zahn 2) observed a reduction in bubble formation (approx. 20%) but still present.

If I assume you running a selective coating machine ? Maybe you have small leak and system is sucking in air creating bubbles in mixture, like a sort of venturi action, just idea, can be a faulty fitting , elbow etc. Have had this before....

I'll try to get some pictures using the Ersa scope this afternoon. Not sure how to post them,may try to send directly to you.I'll take some immediately after coating then of the same after a flash off period.

I haven't had to remove that specific coating before but we regularly remove dow 2577 and other SR with Humiseal 1090 stripper.

I disagree with the others about conformal coating before potting. Some of the softer urethane potting compounds can absorb water leading to caustic nastiness in the voids under the parts. Conformal coating can help fill/seal the voids and keep the n
