Issues Mixing Silicone and Acrylic Conformal Coatings
Issues Mixing Silicone and Acrylic Conformal Coatings
We do a lot of repair PWAs. These assemblies have a silicone based conformal coating. During repair some of the coating is removed. After repair our tech uses an acrylic conformal coat to touch up the area. Could there be a compatibility problem, particularly with adhesion, when we mix these two coatings?
