Tom: Once again - why are you using solvent based conformal coating. 1B31 is OK as a CC but it contains Toluene and MEK!! It is only 35% solids which means you are trying to get rid of 65% solvent. If you must use it due to customers requirement then

We're using the 1B73LOC conformal coating from Humiseal. We've seen some bubbling of the coating. Their tech handbook suggested reducing our oven ramp speed. Does anyone have a good profile for this? They've always pointed me to Nordson, and Nord

We have the same Asymtek machine, same Humiseal product, same bubbling issue on touch ups. Ive found that very light pressure and a thinner mixture usually yields good results for us. Generally I dip the brush in the mixture and let it drip near wher

UV40 for you info was developed in Humiseal EU and has been tested heavily against Dymax product. UV40 is a great product has many approvals from major auto and whitegoods makers.... I have seen comparisons UV40 to Dymax 984LV and Dymax comes out se

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

Just for the record folks, The customer I believe may be manufacturing stuff for refuelling rigs of various forms. This being the case, the coating would need to be resistant against fuels and oils. The UR material (at least ours!) is able to resi
