First, it appears that your solder mask and your coating material appear to be incompatible. Second, IPA leaves a residue that's probably not compatible with your coating material, either. IPC-HDBK-830 - Guidelines for Design, Selection and Applic

My guess would be that the adhesive used on the dots contains silicone. We use 1B73 which is also acrylic and it hates silicone. We use silicone RTV to permanently mask around some connectors and unless its fully cured before coating it will cause l

Your masking dots are a silicone adhesive. Contact the supplier and tell them you need an acrylic adhesive on the same dots. Normally same cost and lead time.

I would suggest trying an acrylic peelable mask. In most cases peelable temporary masks are latex materials. Since you use an acrylic conformal coating it makes sense to use a mask with the same make up to avoid incompatabilities. Link to acrylic mas

There are many liquid masking manufacturers. Some even use acrylic vice latex. Try Contronic Devices. They make their mask in multiple viscosities depending on how you will apply it and where.

We've had great success with acrylic based cut with xylene. Very accurate with little to no masking necessary for keepout areas, very rarely have to make adjustments on our Asymtek. On the other hand we have an Asymtek dedicated for silicone coatin
