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 am using Humiseal 1B31 conformal coating and xylene mix on a PVA coating machine. Bubbles are appearing between the pins of LCCs mainly and bubbling is worse when put through the IR oven. Does anyone have any suggestions or tips to elliminate this

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

thanks for your reply sir, for conformal coating Humiseal 1B31, what are the preferable staking materials? please suggest us..

I would suggest Zymet CN-1703 for staking of the components using this coating material we use it very extensively with Humiseal 1B31, if you would like; I would be happy to coat a couple of your samples for your evaluation.

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.

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

I had send my coating board to the test lab for adhesion coating test. 3 times send, the result 3times fail. The coating chemical use is Humiseal 1B31. The process is clean the boards at washing process use the Vigon A200 saponifier mix with DI wate

We have 2 PVA2400 4 axis selective spray machines that we use to spray Humiseal 1B31 and 1A33. They take a bit of programming to get right, though this is easy to do, but do the job OK. Another to consider if you need the 4 axis of movement would b
