Yes, Hewlett-Packard and now Agilent uses spray-on conductive coatings. We require our vendor to have there process UL approved. If you go to UL 746C it will describe the test method. Paul N. Gardner Company makes a testing set for checking coating adhesion.

The coating works great for EMC, but there seems to be a problem with adhesion and tiny flakes of conductive material getting in the electronics. I'm thinking that the spray-on type materials should not be used at all. Has anyone else experienced this problem?
